Hi Robert, As far as I know, tesselation shaders can be used only with GL_PATCH primitive type. So maybe this flag can be "DrawMode==GL_PATCH" ?
This could also be used in traversal algorithms (such as intersectors) : maybe an optional flag like "ignorePatchPrimitive" ? With this flag set on a Visitor, it should ignores all primitive set of type "GL_PATCH" but still call user-defined callbacks : - don't execute an algorithm that will be wrong (the generic algo cannot be used here) - still execute a user defined algorithm if provided Thank you!
