[osg-users] Converting PrimitiveSet to use triangles instead of triangle strips / fans?

[L. Voerman]

I tend to use
set OSG_OPTIMIZER=INDEX_MESH VERTEX_POSTTRANSFORM VERTEX_PRETRANSFORM
for these, but there might be something else preventing the optimizer from
changing your geometry.
set OSG_OPTIMIZER=STATIC_OBJECT_DETECTION  INDEX_MESH VERTEX_POSTTRANSFORM
VERTEX_PRETRANSFORM MERGE_GEOMETRY MERGE_GEODES
might do the trick
Laurens.
