- Hi,
-
- I have some questions below on the Matrox MG-3D Ultra SXCI
- graphics library. Would appreciate if someone could answer these.
-
- I would also like to get in touch with anyone who is doing work
- using the SXCI library.
-
- Thanks!

- 1) In SetLightSource, if a POSITIONAL_LIGHT_TYPE is specified, there
- doesn't seem to be any effect. The same goes for SPOT_LIGHT_TYPE.
- Only AMBIENT_LIGHT and DIRECTIONAL_LIGHT seems to be working.
-
- 2) Under RendPolyQuad, when are the OptVertexColor fields used? The
- GOURAUD_COLOR and FLAT_COLOR mode do not work (just get a blank).
-
- 3) Is there any way we can specify unique colors for each vertex? I
- suppose the answer will be to use the OptVertexColor, but when are
- these fields read (under which mode)?
