hello

anyone care to update me on Vertex Normals and there possable usages, also what relationship they have to triangle vertex's. also what are "normal" normals?

why would we need these, i know very little about 3d so any help would be great.

Mustang thanks for the link, its useful i understand now they help to control light reflection.

I created a small test example using a triangle and randomly changed the vertext normal to see its affect.

cheers

ive just been looking into collision normals would CollisionNX()/CollisionNY()/CollisionNZ() return the angle of the collision.
