How to use 3D Tiff as an Elevation Grid?
How to use a 3d tiff (32 bit float) generated from ArcGIS to show the data in 3D, without re-grid surfaces from our data again. Let’s assume your GeoTIFF has single channel 32-bit data representing elevation.
1. Load GeoTIFF & set output file name
2. Set extended log to watch out for any errors or warnings
3. Set subsample, Tin options especially helpful for larger grids
4. Set elevation colormap, its range, assign GeoTIFF channel to control elevation in 3D surface, set null-data flag value.
3D TIFF format is not supported for stack of images mode, for Volumetric or VOXEL display. Adobe Reader 3D PDF display only supports 3D geometry, without any direct volumetric rendering. Alternatives are to use level-set isosurfaces, or a series of slice planes with per-pixel transparency.
