WebglPushMatrix pushes a copy of the current matrix onto the current stack, while glPopMatrix pops the top of the stack (changing the current matrix to whatever was just below the top). Note: the stack depth limited (though at least 32 for GL_MODELVIEW and at least 2 for the other modes including GL_PROJECTION ), so be careful how many things you push. WebMatrix stack: A bunch of transformed matrices.In the old fixed function pipeline, OpenGL built-in matrix stack can be used. In the new functional pipeline, stack can be used for simulation.

"WebRotation matrices have explicit formulas, e.g.: a 2D rotation matrix for angle a is of form: cos (a) -sin (a) sin (a) cos (a) There are analogous formulas for 3D, but note that 3D rotations take 3 parameters instead of just 1. Translations are less trivial and will be discussed later. They are the reason we need 4D matrices. " - Opengl matrix stack
