Hi, I am a newbie to OpenGL. I am learning to use the glDrawElements function. Using Blender, I have made a vertices of a somewhat complicated shape, but now I am stuck because I don’t know how to make the indices array of the vertices. It seems impossible to do it by hand, is there some special software that can generate the indices?

Another question is kinda related, how do I made the Normal vertices?

Thanks in advance.
