The winding I know, but I've not yet drawn or calculated the normals as I'm a bit confused on that. Isn't there a normal for each side? Or is the normal only on the side where I choose the winding order?
Normal is a per vertex information, that is, it is on each vertex. Sometimes all three verticies of a triangle has the same pointing normal called triangle normal, what is a normal perpendicular to the triangle the verticies form. Sometimes there are duplicated verticies becouse of unique normal but shared position, take for example a cube- a corner vertex has one position but three distinct normals, each perpendicular to one of the shared triangles, thus you have multiple verticies to conform multiple distinct triangles, they just have a common position.
