Can someone give me a way to find the normal for each primitive using my class structure. My fragmented structure:
Object: holds an array of verts and an array of primitives that make up object.
Primitive: holds indices that make up this primitive.
VERTEX: x, y, z coordinates
I've been coding for quite awhile today and i just can't think how to get this w/ my class structure. I'd like to have a method in my Primitive class that calculates the normal for that particular primitive, it it possible to do so with just indices and no verts? Ideas and suggestionns please!!??
