Notes
Geometry_Options provides geometry-specific details for drawing. Note that these options are specific to individual geometry elements, unlike the geometry options defined as part of TKE_Rendering_Options, which affect entire classes of geometry items. For the specific definitions on what these mean in HOOPS/3dGS please refer to the Set_Geometry_Options specification in the 3dGS Reference Manual.
Mask/value bits
| 0001 | orientation_count and orientation are present |
