SoVolumeRenderprojectedTileSubdivision Property |
When doing volume projection (see OIV.Inventor.Nodes.SoProjection), only the geometry (corner vertices) of the LDM tiles are projected, not the individual voxels.
Namespace: OIV.VolumeViz.Nodes
This can produce an imprecise projected volume when using large LDM tiles or low resolution levels (where the LDM tiles are larger).
This field controls how many times the tile geometry will be subdivided (producing more vertices) before being projected. Subdivision gives a smoother, more accurage shape, but requires much more computational power and may reduce rendering performance. Default is 1 (subdivide once).
NOTE: This field is ignored in raycasting mode (the default).
If not in raycasting mode, you should set #gpuVertexGen to true when using this option. NOTE: field available since Open Inventor 7.1
