It’s me again, hehe.
I’d like to know which may be the best algorithm to calculate the silhouette edges.
My object data is stored something like this:
Object: ... Array of faces-> a,b,c (vertexes) ta,tb,tc (texture coordinates for each vertex) Array of vertexes-> x,y,z (position) nx,ny,nz (normal) ...
Which could be the best way to know the silhouette edge?
May I add a index of neighbour faces to each face?
I couldn’t find a tutorial on the web which I can really understand.
