hi i am beginner i am trying to implement bump mapping with vbo and glsl. My question is: did i make bump mapping ? if i did why these edges didnt disappear ?
That's not how bump mapping works. Bump mapping adds additional detail to a model, but doesn't change the triangles. You need to render a mooth mesh to make the edges invisible (the normals of a vertex shared by 2 triangles must be the same)
