SoVolumeIndexedTriangleStripSetoffset Property |
Sets an offset value used for computing the texture coordinates.
Namespace: OIV.VolumeViz.Nodes
The texture coordinate for each vertex will be taken from a point offset units away from the vertex. The offset is measured in the direction of the vertex normal. By default the offset is equal to 0 (no offset). When using this feature, a vertex normal must exist for every vertex. If vertex normals are not supplied, Open Inventor will compute vertex normals in the usual way except that the crease angle will be fixed at PI in order to assure that a vertex normal is computed at every vertex.
