Hello,
what are the math subjects i need to start learning in order before i dive in into the learning world of opengl 3d application creating?
is it Algebra or Trign or Matrixes or vectors?
I need to know the topics in order so i can start learn them one by one before i dive into opengl Apis programming.
It depends on what you want to do. At least you'll need to understand how coordinate system transformations work (i.e. going from one frame of reference to another), and how to use matrix multiplication with vectors to do that.
Read the Viewing chapter in the OpenGL Programming Guide and branch off from there. For a high-level skim of this material, see OpenGL Transformations (this references some legacy GL calls but the basic concepts still apply).
