Hi all,
Getting back to something I had to set aside earlier. I have computed a surface normal for each face/triangle of my model. My resulting normal is a Vector3d.
Now my question is, how do I tell what side of a triangle this normal is on? I think by doing this, it will tell me what side can be the front and back of my surface.
Does this sound correct?
The front side is determined by the order the vertices are created. The default order is counter clockwise. You can change the default with glFrontFace.
I need another way other than order of vertices, as this is something I can’t count on.
I dont think there can be any other way. modelling programs will usually save models with verts listed cc so its not a problem.
