understanding Q3TriMesh_EmptyData

[Joseph J. S. <jo...@st...>]

I'm trying to get some TriMesh data out of a display group, work with 
it for a while in immediate mode, and then release it, and be able to 
get it again.  I get the data with Q3TriMesh_GetData, whose docs say 
that it will allocate memory, which I must free by calling 
Q3TriMesh_EmptyData.  But once I've done that, calling 
Q3TriMesh_GetData again on the original TQ3GeometryObject gives me a 
TriMesh with no attributes; both texture and diffuse color have been 
lost.

Unfortunately, I'm not set up at the moment to test this under QD3D, 
so I'm unsure whether this is a bug in Quesa, or an error on my part. 
It's acting as though Q3TriMesh_GetData is not actually cloning the 
attributes, yet Q3TriMesh_EmptyData is nonetheless releasing them.

Does anyone have any insight to share?

Thanks,
- Joe
