I've tried to use the cva extention, and I've got strange behaviours :
- the polys that are near the screen borders are colored with the current color ( ie with glColor...),
- when texturing is turned on, the speed goes down...
My rendering function is :
glVertexPointer ( ....) ;
glNormalPointer ( ... ) ;
glTexCoordPointer ( ... ) ;
glLockArraysEXT ( 0, nbVertices ) ;
glDrawElements ( ... ) ;
glUnlockArraysEXT ( ) ;
And nbVertices is less than the max cva buffer size...
I use dynamic lighting ( 1 light ), and nothing else special...
Do anybody have the same problem ? Is it a bug, or a problem with my code ?
For information, my configuration is a K6-2, a Voodoo2, and XFree4.0 with Mesa 3.2.1.
