[osg-users] polygon index error

[Michele Bosi]

I have a strange problem with my marching cube algorithm when the mesh
generated is bigger than 3700 polygons more or less (I am using
indexed polygons).
The problem seems to be the Linux MESA driver (Ubuntu 7.04) since
under WinXP everything works well.
I also tried to disable the display lists and VBOs to see if the
driver reacted in anyway but with no result.

Did anyone experienced a similar problem?
Is there any OSG/OpenGL limit (maybe platform or driver dependent) to
the polygons one can insert in an osg::DrawElementsUInt?
Cutting the mesh into 3500 polygon chunks could be a temporary (and
poor) solution... any other suggestion?

Thanks,
Michele
