PDF3D-SDK General Changes
1. New PDF3DFontTessellator Class, creates geometric vector representation of a text string and specified font.
  The PMI generation system now makes use of the new PDF3DFontTessellator system. To add a text to PMI one should use the result of the new tessellation, received from PDF3DFontTessellator.
  The PDF3DFontTessellator Class can import and use an external font file and includes the following methods:
```
  GetAscent,
  GetDescent,
  GetSpaceWidth,
  GetSymbolAdvance,
  GetSymbolHeight,
  GetSymbolWidth,
  GetSymbolSize,
  GetLineHeight,
  GetTextAdvance,
  GetTextHeight,
  GetTextWidth,
  GetTextSize,
  GetTextAdvance,
  GetTextHeight,
  GetTextWidth,
  GetTextSize,
  TessellateSymbol,
  TessellateText,
  GetPoints,
  GetTessellation
```
  Any external True-Type font file can be used for symbol and text styles in PMI, such as the the widely adopted GD&T set:
```
     PDF3DFontTessellator fontTess("Y14_5M-2009.ttf", true);
```
2. Advances to low level PMI and PRC processing. Previously only line drawing and text was supported, with API unable to create polygons and triangles. Now the ability to add triangles and polygons within PMI is added.
3. The support of the Face View, Frame Draw, Fixed Size modes has been significantly revised and optimized. Frame Draw creates the group, which consists of the fixed size geometry without billboarding, so it can't be turned from the specified orientation.
  For the Face View, Frame Draw and Fixed Size modes, functions for supporting triangles and polygons to PMI annotations were also added.
4. Developers can use the PMI XML metasystem, or the PMIAccessInterface and the PDF3DPMIMarkup classes.
  Both PMIAccessInterface and PDF3DPMIMarkup were upgraded.
  Various high-level classes for drawing have been added.
  The XML metasystem contains the following new types (with corresponding class API methods):
```
  PMIBeginTriangle, PMIEndTriangle - add one triangle
  PMIBeginTriangles, PMIEndTriangles - add a set of triangles in one operation
  PMIBeginPolygon, PMIEndPolygon - add a polygon
  PMIOpenFixedSize, PMICloseFixedSize - add a scalable (not a billboard) group
  PMIOpenLineStyle, PMICloseLineStyle - set line style (only color takes effect)
```
5. Dimension and lead-line Arrowheads are now drawn with triangle filling instead of using two line segments.
6. Oriented views can be captured and turned into illustrated buttons for user selection. To create the thumbnail buttons with images of actual 3D objects, developers should use the PDF2DSceneDrawer class, which allows to draw the scene on the XObject type on a PDF page. An XObject should be created inside the PDF user-defined style, which is applied to the button. The example can be found in the PMI_IS source. To make use of this class start with the MCRConvert2D.h header file (line 34). The example of the "user style" - lines 94 -172, the example of the "thumbnail with the line style usage" lines 349 -372.
7. Added FontTessellation example, showing how tessellated text can be generated using Intermediate Storage classes API

10. Revised unit processing logic. The input units of all assemblies are processed by the following algorithm:
  1. If ModelUnitType parameter is specified exactly (i.e. it is not equal to ModelUnit_is_NotDefined value)
    then all models will be converted from input units to the exactly specified ModelUnitType.
  2. If ModelUnitType parameter is not specified exactly (i.e. it is equal ModelUnit_is_NotDefined value)
    then program iterates through input assemblies (in original order).
    For each assembly it performs the following:
    1. If xyUnits of the current assembly is not equal zUnits of the current assembly and
      zUnits can be assigned to ModelUnitType parameter.
      In such a case XY coordinates are converted to zUnits.
      Also ModelUnitType parameter is forced to zUnits parameter value.
      Program converts all the rest assemblies to ModelUnitType parameter.
    2. If xyUnits of the current assembly are not equal to zUnits of the current assembly and
      zUnits can not be assigned to ModelUnitType, but xyUnits can be assigned to ModelUnitType.
      In such a case Z coordinates are converted to xyUnits.
      The ModelUnitType parameter is forces to xyUnits parameter value.
      Program converts all the rest assemblies to ModelUnitType parameter.
    3. If both xyUnits and zUnits of the current assembly can not be assigned to ModelUnitType then the
      program processes the rest assemblies (checks for conditions a, b and c).
  As a result of such processing target units should be selected.
  If ModelUnitType is still ModelUnit_is_NotDefined and
  output coordinate system is some type of geospatial coordinate system
  (either exactly specified geodetic or projected coordinate system, or automatically detected geospatial coordinate system)
  then ModelUnitType is forced to meters.
  If the output coordinate system is geospatial coordinate system
  then degreesPerMeter parameter is not used, and used geospatially correct transformations.
  Note that xyUnits and zUnits can be applied to any input assembly, but not for GRD_Interface only.
  The deprecated parameter degreesPerMeter is used only when the output coordinate system is generic cartesian.

  1. If ModelUnitType parameter is specified exactly (i.e. it is not equal to ModelUnit_is_NotDefined value)
    then all models will be converted from input units to the exactly specified ModelUnitType.
  2. If ModelUnitType parameter is not specified exactly (i.e. it is equal ModelUnit_is_NotDefined value)
    then program iterates through input assemblies (in original order).
    For each assembly it performs the following:
    1. If xyUnits of the current assembly are not to equal zUnits of the current assembly and
      zUnits can be assigned to ModelUnitType parameter.
      In such a case XY coordinates are converted to zUnits.
      Also ModelUnitType parameter is forced to zUnits parameter value.
      Program converts all the rest assemblies to ModelUnitType parameter.
    2. If xyUnits of the current assembly are not equal to zUnits of the current assembly and
      zUnits can not be assigned to ModelUnitType, but xyUnits can be assigned to ModelUnitType.
      In such a case Z coordinates are converted to xyUnits.
      The ModelUnitType parameter is forces to xyUnits parameter value.
      Program converts all the rest assemblies to ModelUnitType parameter.
    3. If both xyUnits and zUnits of the current assembly can not be assigned to ModelUnitType then
      program process the rest of assemblies (checks for conditions a, b and c).
  As a result of such processing, a target units should be selected.
  If ModelUnitType is still ModelUnit_is_NotDefined and
  output coordinate system is some type of geospatial coordinate system
  (either exactly specified geodetic or projected coordinate system, or automatically detected geospatial coordinate system)
  then ModelUnitType is forced to meters.
  If output coordinate system is geospatial coordinate system
  then degreesPerMeter parameter is not used, and used geospatially correct transformations.
  Note that xyUnits and zUnits can be applied to any input assembly, but for GRD_Interface only.
  The deprecated parameter degreesPerMeter is used only when the output coordinate system is generic cartesian.

GRD_Interface
1. Changed logic of xyUnits and zUnits parameters processing.
  Previously GRD_Interface converted all coordinates from the specified units to meters.
  Currently GRD_Inteface marks the input specified units in the output document,
  instead of performing actual unit conversion. The unit conversion is performed in the following cases:
  1. If xyUnits is not equal zUnits and zUnits can be assigned to ModelUnitType
    parameter. In such a case XY coordinates are converted to zUnits. Also ModelUnitType
    parameter is forced to zUnits parameter value
  2. If xyUnits is not equal zUnits and zUnits can not be assigned to ModelUnitType
    but xyUnits can be assigned to ModelUnitType. In such a case Z coordinates are
    converted to xyUnits. The ModelUnitType parameter is forced to xyUnits parameter value
  3. If both xyUnits and zUnits can not be assigned to ModelUnitType
    then all coordinates are being converted to meters. ModelUnitType is forced to meters also
2. Added optimization for colormaps 1D Texture generation mode. However, this mode
  can be used only with a limited number of cases: it does not work with decimated

  Previously PDF3DReportGen and GRD_Interface converted all coordinates from the specified units to meters.
  Currently PDF3DReportGen and GRD_Inteface marks the input specified units in the output document,
  instead of performing actual unit conversion. The unit conversion is performed in the following cases:
  1. If XY Unit is not equal to Z Unit and Z Unit can be assigned to Model Units Type
    parameter. In such a case XY coordinates are converted to Z Unit. Also Model Units Type
    parameter is forced to Z Unit parameter value and becomes gray-out
  2. If XY Unit is not equal to Z Unit and Z Unit can not be assigned to Model Units Type
    but XY Unit can be assigned to Model Units Type. In such a case Z coordinates are being
    converted to XY Unit. The Model Units Type parameter is forcef to XY Unit parameter value
    and becomes gray-out
  3. If both XY Unit and Z Unit can not be assigned to Model Units Type
    then all coordinates are converted to meters. Model Units Type is forced to meters also and becomes gray-out
7. Added new item None in View Scheme combo box control. It allows not to add any default view

4. Axes Elevation now does: displacement on X for YZ selected axes, displacement on Y for XZ selected axes, displacement on Z for rest cases
5. Extended RigidAnimation's so it can be used to animate both models and camera (one rigid animation can contain just camera movement, just model movements or both)
6. Extended RigidAnimation's API for advanced set opacity modes. Please see reference documentation about PDF3DRA_EOpacityMode enumeration type and PDF3DRANodeMovement structure
7. Improved set opacity methods in layer separation and model tree systems

17. Removed dependency from page orientation for SetPageWidth, GetPageWidth, SetPageHeight and GetPageHeight functions in PodofoLayer. It was done because, when getting orientation, rotation entry of annotation's dictionary is used. This attribute does not change page's geometry (just rotates page by the given angle), but so does swapping width with height

3. Changed PDF3DExporter::SetLayerSeparationSystem() method. Now it accepts arguments into a structure parameter rather than a lot of arguments; Also this method implements "distance-100" calculation algorithm (calculates disatance for 100% layer separation mode which is based on layering direction and scene bounding box dimensions)
4. Changed PDF3DExporter::SetLayerSeparationControls() method. Now it accepts arguments into a structure parameter rather than a lot of arguments
5. Changed PDF3DExporter::SetLayerSesparationFlashControls() method. Now it accepts arguments into a structure parameter rather than a lot of arguments

The similar method was added for PDF3D_C4V template, it is PDF3D_C4V::IsNearZeroW() method
8. Added new methods into PDF3D_C3V template: PDF3D_C3V::MaximalValueIndex(), MinimalValueIndex() which returns index of maximal and minimal value of vector component array (0 index means for "x" component, 1 index means for "y" component, 2 index means for "z" component)
9. Added _worktype& operator()(size_t index) and _worktype operator()(size_t index) const in PDF3D_C3V template. The "const" version of overloaded operator returns value of the specified component by index (0 means for x, 1 for y, 2 for z). And non-const version returns reference to the specified component. The appropriate implementation was added for PDF3D_C4V template also
10. Renamed methods PDF3D_C3x4M::fillArray() to PDF3D_C3x4M::SaveToArray(), PDF3D_C4x4M::fillArray() to PDF3D_43x4M::SaveToArray(), added the following methods:

PDF Font generation extended, now automatically recognizes the Adobe built-in "Base14" fonts, avoiding font embedding, and making file sizes smaller. Built-in font references are recognised for:
"Courier", "Courier-Bold", "Courier-Oblique", "Courier-BoldOblique",
"Helvetica", "Helvetica-Bold", "Helvetica-Oblique", "Helvetica-BoldOblique",
"Times-Roman", "Times-Bold", "Times-Italic", "Times-BoldItalic",
"Symbol", "ZapfDingbats". In cases where the PDF is text only, with an embedded TTF font, file size can go from 400kb down to less than 3Kb by using these built-in fonts. These are already present in the Adobe Reader on all Adobe platforms. This also is a good solution where font files may not be readiliy available on various Linux systems. Note, these fonts only support Latin-1, so other language or unicode character sets cannot be used with Base14. Bold and Italic attributes now mapped to Base14 variants.
zlib refactored to name-mangled internal version, zlibvtsl (lib, dll), link library list API has changed!
AddDefaultView method added to Conversion Manager, users can specify names, order, plane normals, view direction, look "up" vector, etc. based on model bounding box, without requiring explicit coordinate information.

MixedSurfaceLines added to examples, showing a simple worked example of a scene with mixed triangle mesh and lines, using access interface API, illustrating AboutToBeginModel() method.
MixedSurfaceLinesIS added to examples, showing a simple worked example of a scene with mixed triangle mesh and lines, using intermediate storage (IS) interface API.
Windows library linking dependencies changed, now requires Ws2_32, RpCrt4, Linking library list API has changed!
Linux library linking dependencies changed, now requires uuid in some cases, link list API has changed!
IFXCore, Plugins removed, all U3D services are now provided by pdf3d.lib / pdf3d.a, runtime DLLs removed, Plugins directories removed. Link library list API has changed!.
PDF3DViewAccessInterface::ConfigureResourceViewNode(IFXView *viewNode,
IFXViewResource * viewResource) and the PDF3DSceneInterface::ConfigureRootNode(IFXNode* rootNode) are removed. API has changed!
GradientBackground API added allows setting two unique colors for top to bottom gradient shading as scene backgrounds. Affects all views. Added to several examples, as exporter.SetBackgroundColor(options, 0.13f, 0.21f, 0.32f, 0.70f, 0.71f, 0.77f).
Camera View Matrix CameraLookAt() helper function added, specifying arbitrary camera position, look direction vector and up vector, forming transformation matrix, with example usage shown in CubePoints.
PDF3DTableCreator, added TableRightMargin parmeter to set when page size is made wider to fit table, changed default fonts used in TableToPdf example to use Base14 fonts for much smaller file size
PDF3DSceneInterface is extended by the following methods:
GetRootNodeTransformation()
PDF3DIntermediateScene is extended by the following methods:
GetName() & SetName()
SetRootTransformationMatrix() & GetRootTransformationMatrix()
PDF3DIntermediateScene::GetName()\SetName() returns\sets the scene name
GetRootTransformationMatrix()\SetRootTransformationMatrix() returns\sets the scene root node transformation matrix (similar to PDF3DSceneInterface::GetRootNodeTransformation(), but work for IntermediateStorage classes)
added PDF3DIntermediateCamera::GetFieldOfView(), SetFieldOfView(), PDF3DIntermediateCamera::GetAspect(),SetAspect()
which are the similar to the appropriate PDF3DViewAccessInterface' s methods. These methods can be helpful in adjusting the 3D PDF scene coordinate system to match the calling application coordinate system.
PDF3DMeshAccessInterface::GetTextureImage() API has been changed!
Important API Change Notice, Warning: There are now have 3 methods in place of single method, all applications should be updated. The access interface now always calls to get width and hieght before asking for texture image buffer. (These calls are skipped if texture is already cached):
virtual int GetTextureWidth();
virtual int GetTextureHeight();
virtual void GetTextureImage(unsigned char* data,size_t allocatedBufferSize);
In GetTextureImage() routine, developer should only copy texture data to data buffer, allocated by SDK (size is specified by allocatedBufferSize variable). Before copying, size of passed allocated buffer should be checked. There is no need anymore for allocating new buffer and passing it to SDK.
PDF3DSceneInterface::SetPreview() method, API has changed! Now applications are responsible for removing the memory block after SetPreview() call, such as with: unsigned char* data = new unsigned char[length]; (fill data); SetPreview(width,height,data); delete[] data; See CubeScene for working example.
Character string arguments in API methods are now of different type and used differently, API has changed! this will require minor revision to applications, improves memory handling stability across interfaces. In general terms, std::string type has been replaced with char*. Now instead of called method allocating strings, the caller is expected to pre-allocate string buffers and pass the size of this buffer explicity in the argument list. Please note the revised argument specifications in: PDF3DIntermediateModel::GetName(), PDF3DIntermediateModel::GetLabel(), PDF3DIntermediateModel::GetMetadataItem(), PDF3DIntermediateModel::IndexedFaceSetVRML97(), PDF3DIntermediateModel::IndexedLineSetVRML97(), PDF3DIntermediateModel::PointSetVRML97(), PDF3DIntermediateModel::ExtrusionMeshVRML97(), PDF3DIntermediateModel::ElevationGridVRML97(), PDF3DIntermediateCamera::GetName(), PDF3DIntermediateCamera::SetName(), PDF3DIntermediateLight::GetName(), PDF3DIntermediateLight::SetName(), PDF3DIntermediateScene::GetName(), PDF3DIntermediateScene::SetName(), MeshAccessInterface_Impl::GetCurrentMeshName(), PDF3DModelInterface::ContextType(), MeshAccessInterface_Impl::GetMetadataItem(), PDF3DMeshAccessInterface::GetMetadataItem(), PDF3DLineSetAccessInterface::GetCurrentLineSetName(), PDF3DContextSensitiveInterface::GetContextName(), PDF3DSceneInterface::GetSceneName(), PDF3DViewedHierarchyImplementation::GetViewedName(), PDF3DViewedHierarchyImplementation::GetUnderlyingModelName(), PDF3DIntermediateViewedHierarchy::GetViewedName(), PDF3DIntermediateViewedHierarchy::GetModelName(), PDF3DTexture::PDF3DTexture(), PDF3DTexture::GetTextureFileName().
Inline Memory Allocation Methods
It's not safe to directly allocate or free heap memory in an inlined function, because it can cause crashes on MS Windows systems if the runtime library used in the shared library is different from the one used by the executable calling that DLL. Using malloc and/or new in inlined methods will lead to crashes on MS Windows systems. New PDF3D-SDK methods are introduced to overcome this issue. At any API call involving std::vector, std::map, std::set should now be replaced with non-inline safe methods:
- PDF3DVector<>template
- PDF3DMap<>template
- PDF3DSet<>template
This should be a simple replacement in all applications using PDF3D-SDK API. If a program is compiled without this change, a compile time error will be thrown.
JavaScript Single Insertion. Some JavaScripts are now inserted only once, rather than multiple times, resulting in smaller file size in some cases.
ICC Color profile srgbprofile.bin is now embedded into PDF3D-SDK, eliminating need to manage an external resource file.
podofo.dll is now removed, all methods are now part of the main pdf3d.lib library system.
PDF3DCheckOutputAvailability() method is added to PDF3D-SDK, a service to allow applications to quickly check if write or append access to the output file is available, before wasting time in conversion.
CPACK configurations are now added into interface CMakeLists.txt, allowing the generation of installers for individual applications.
U3D Memory Usage API deprecated, now returns zero.
CHM Help (compiled html) sytem for searchable reference to full API, examples, interfaces (on Windows platforms)
ModelToPdf3d (dot net) interface removed, deprecated.
PDF3DConversionManger::IsFormatEnabled(Format3D) method added, allowing applications to check which encoding methods are available at runtime, for GUI configuration control, etc.
PDF3DConversionManager::SetCreaseAngle() method added, for non-stored normals interpretation, threshold angle for when normals should be smoothed or sharp edges preserved.
Use Original Normals (storing them in PDF file) default value is not reversed to be False unless explicitly set, as automatically generated normals have high performance and smaller file size. Crease angle may be adjusted to achieve desired effects.

LOD Level selection parameters, highest or lowest detail when level of detail options available in input file. Parameter added to VRML interface. Coin interface (wrl, iv), PDF3DXmlServer, PDF3DReportGen GUI and other interfaces where LOD information is available.
Initial animation control state bug fixed, some animations would not start up in the correct looping mode (pingpong or smooth)
VRML imported Viewpoint correction, now sets PDF camera rotation parameters based on vector (VIEW_POSITION - ACTUAL_CENTER_OF_SCENE) rather than magnitude of current view position
PDF3DXmlServer Rotation XML input specifying object rotations uses an axis of rotation vector plus angle in radians. Previously if the axis of rotation vector direction was not unit length, would cause shear transformation rather than pure rotation. New behaviour added to normalise vector length internally, so XML may now specify vectors of any magnitude, only the direction will be used.

Multiple Pre-compiled binaries and dlls: Please note that the installation process detects if you have VS2003, VS2005, VS2008 compiler environmnets installed, and sets the PATH environment variable appropriate for that version of binary programs and accompanying dlls. If you try to run another type, these will fail due to the incorrect PATH environment. This can easily be corrected by manual intervention, as follows:

You need to setup environment variable PATH to
$INSTDIR\PDF3D-SDK\bin\VS2008_RunTime\ to use samples from VS2008_Binaries
(instead of $INSTDIR\PDF3D-SDK\bin\VS2005_RunTime\ or
$INSTDIR\PDF3D-SDK\bin\VS2003_RunTime\ ).

You need to setup environment variable PATH to
$INSTDIR\PDF3D-SDK\bin\VS2005_RunTime\ to use samples from VS2005_Binaries
(instead of $INSTDIR\PDF3D-SDK\bin\VS2008_RunTime\ or
$INSTDIR\PDF3D-SDK\bin\VS2003_RunTime\ ).

You need to setup environment variable PATH to
$INSTDIR\PDF3D-SDK\bin\VS2003_RunTime\ to use samples from VS2003_Binaries
(instead of $INSTDIR\PDF3D-SDK\bin\VS2005_RunTime\ or
$INSTDIR\PDF3D-SDK\bin\VS2008_RunTime\ ).
PDF Resources: new classes are added to support U3D resource additions to the 3D PDF scene, for use by advanced javascript methods. These are PDF3DExporter::AddU3DResourceTo3DAnnotation() and PDF3DExporter::Clear3DAnnotationResources().
VISTA installation process and operation now supported.
NSIS Installer updated to 2.37, with logging enabled.
3D Label model bug fixes, one bug caused fatal font loading errors in some circumstances. Label rendering now improved for black labels on white background or white labels on black background, where they appeared "washed out" before, fix involves changing material characteristics of label textures. New API methods allow setting label origin; SetOrigin(x,y) to allow right or left justify or center modes. Also 3D label horizontal or vertical orientation control has been added. The source example LabelTest now includes these new features.
HyperLink example and API extensions- shows how to attach mouse click hyperlink behavior to any 3D node or object. The hyperlink destination can be another page in the same PDF, a bookmarked area on some page, another PDF file nearby on the same filesystem, or an external web page.
Metadata packets can now be associated with nodes of the U3D data structure. This metadata can now be interactively revealed in a special panel on the PDF page, activated on mouse click on the corresponding 3D object. New API method PDF3DExporter::SetMetadataOutputControls() is able to interactively show metadata from selected objects. Metadata must be already present in 3D data structure.
Input PDF Document Security Check. When injecting 3D into existing documents, the input document should not have any security settings. There is a new API method to use to check this condition before wasting time on 3D conversion.
Use bool PDF3DExporter::IsPDFDocumentSecured(const char* szFileName).
Acrobat 9 Pro Extended, Adobe Reader 9 compatibility fixes for stored view point list.

What's new in PDF3D Version 1.5.0 ?

LM-X floating network license server on Linux, bug-fix improvements.
PDF layer update, embedding improvements. New version of podofo.dll, allows injecting on pages with JPEG images, etc.
VRML2PDF3D utility now has option to show PDF on completion. This utility is now more or less redunant, we recommend using the PDF3DConverter application intead. This may be withdrawn entirely in a future release.
Intermediate Storage classes, new addition, PDF3DIntermediateModel(), allows simplification to coding many types of interfaces. These classes are now used by VRML, Coin3D, Open Inventor, STL interfaces. A form of these functions were previously local to each interface. Now this code is refactored into common services in PDF3D-SDK API, rather than locally in each interface. These include class PDF3DIntermediateScene, PDF3DIntermediateModelData and PDF3DIntermediateModel classes.
Polygon Tessellation. PDF3DPolygonTesselatorXZ and PDF3DPolygonTesselator classes are added, appropriate where large concave polygon data types must be triangulated. This is currently used on VRML files, for instance, were IndexedFaceSet has larger polygons than triangle types.
OEM License Activation macro now centralised at include/PDF3Didxm.h, OEM customers now receive pre-configured OEM source.
PDF3DConverter interactive application, now replaces VRML2PDF3D application, handling multiple file types, including WRL, STL, IV. This GUI dynamically configures available file type conversion based on runtime DLLs. (Windows ONLY)
STL_Interface now has preset mesh color, rather than randomly selected color. The internal implementation has been re-written to use the intermediate storage classes. Previously there was an error in the way model name was processed from the file, this is now fixed.
Open Inventor interface removed from distribution. Available on special request basis.
PDF3D License Utility updated to show current software build details, full path of license file. Note also placement of license file has changed with this release, will always be placed under PDF3D_ROOT, unless you set environment variable PDF3D_LICENSE_PATH. If you set this explicit path you will need to move your license file to this place or request a new license.
MS Visual Studio 9 (2008) support, excluding LMX license version.

VRML2PDF3D interactive program with user interface. To allow easy evaluation and testing, we now supply a full GUI based application for converting VRML models to 3D PDF. This allows most of the parameters normally set by command line arguments or dll arguments to be set interactively. The new program may be launched directly from the Start menu.
Microsoft Visual Studio 2005 update to SP1. SP1 is now REQUIRED to build and run on Windows. If SP1 is not installed, the installer will provide "vcredist_x86.exe" installer for Microsoft redistributable runtime files. This will allow precompiled binaries to run for evaluation and test purposes.
"String" symbol change. REQUIRES APPLICATION SOURCE CHANGE. We have found that one of the API defined symbols "String", sometimes clashes with the same symbol defined in other existing applications. We have now redefined this symbol, so if you are using it, please adjust your source to now use "PDF3DString".
CMAKE installer added. As most of the examples and interfaces require CMAKE during the build procedure, we now distribute CMAKE as part of the install package, to avoid the need to find, download and install this separately.
VRML_to_PDF3D has additional parameters to specify title, caption, page size, margin layout, and injection of 3D view into existing PDF documents.

3D Labels. New PDF3DLabelModel uses alpha-blending and True Type fonts to place text labels in the 3D scene. These may be oriented and controlled like glyphs. Text may be normal ASCII or Unicode. An example application "LabelText" shows them in operation, including Kanji Japanese font support.
Label Dynamics class. A new PDF3DExporter::SetLabelDynamics() class enables runtime billboard effects, where labels are transformed to be oriented toward the camera.Note, is only effective if viewer is using Adobe Reader 8.1
LM-X Floating Network Server option. For enterprise customers, a new floating network licensing system in introduced. Please contact the company for more details. A new alternative license utility is provided, PDF3DLicense2.exe, plus files in the PDF3D-SDK\lm-x directory. A separate install package is provided to users of the LM-X option.
Powerpoint PDF Viewer add-in, allowing interactive 3D PDF files to be shown in PowerPoint presentations. This involves installing a free 3rd party tool "LiveWeb" during the installation procedure. A sample PowerPoint demonstration is included in the "samples" directory. The installer for "LiveWeb" is included with permission of the author and may be distributed to users without license or payment..
DrawText() bug fix for hyphens. If the input text contained a hyphen (-), DrawText() would previously output the text without the hyphen.
PDF3DPDFOptions Producer field can now be freely set to any user string.
Background Color to 3D scene, if using automatic centering default view, will inherit background color from user specified settings or 1st custom view point. Previously all backgrounds were black if automatic default view was enabled.
