Would 3d modeling experience be a must for OpenGL?
Thank you.
That.. plus 3D maths, OpenGL api's, OOP... and a gazillion other things.
So.. the more you know, the better! :wink
3d modeling experience is not necessary for programming in OpenGL. Modelers do the models and texturers do the textures. Plus you can buy fully rigged models online.
Math on the other hand is a MUST both for OpenGL and Direct3D.
