i have a question about normal vectors. i’m currently trying
to write a library that uses opengl. i choose buffer objects
to store my models. now i decided to add light, so i needed
normal vectors. i made an attempt and i didn’t like the result.
so i sat down and started to thinking. with the buffer objects you can define one normal vector for each vertex. i figured that this is not going to work. to draw a cube, for each vertex
you need three normals, by logic, one for each side. i
opened 3ds max to check and it is like that. am i wrong?
how can i achive this in openGL?
