Setting normals on faces

[Cucus]

Hi,

Is there a way to setting up normals just for faces (and not for vertices) without doing an interleaved array?

If I understand, when you do glNormalPointer and glVertexPointer, you're assuming that there's the same number of normals than vertices.

I'm right?

No. Well, "interleaving" isn't necessary, but they both still must be arrays. If you want the effect of a face having a normal, then every vertex on that face must have the same normal. That will require adding a lot of extra positions to your arrays.

Ok, thanks!
