Is the normal considered when rendering?
« on: June 16, 2006, 11:05:14 am »
Hello

Is the vertex's normal of a facet considered while rendering?
I did not find a method to set normal of each vertex of triangles.

Of course they are. There is no obvious method to set them directly, because you usually don't have to care about them. They are calculated internally when calling build(). If you really want to modify them, you may do this by extending the GenericVertexController.
