Hello.
Recently we have tried to make a few very simplified houses in our

Normals are created for the walls and point out of the house.
The problem we see is that when creating the normals, only the first one is
Hi Werner,
BIND_PER_PRIMITIVE will require a normal per quad, even when its in a strip.
BIND_PER_PRIMITIVE_SET will require a norm pwer primitive set.
BIND_PER_PRIMITIVE will force the OSG down on to OpenGL slow paths as
non of the fast paths support this type of usage so I wouldn't
recommend
So splitting each quad in the quad strip down to single primitives/Quads
and creating a normal pr. vertex would be faster even though it creates
more data?

Hi Sherman,
The drawImplementation is const as a hint to the developer that draw

Use of mutable variable is the easiest way to get round a const.
