WebThis allows to chain multiple transformations in the same way as with OpenGL's legacy matrix stack operations, and allows to decompose the resulting effective matrix as a decomposition of multiple matrix multiplications. One such common decomposition are the projection and modelview matrices, written as: P * MV.

WebSpecifies which matrix stack is the target for subsequent matrix operations. Three values are accepted: GL_MODELVIEW, GL_PROJECTION, and GL_TEXTURE.The initial value is GL_MODELVIEW.Additionally, if the 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. ctk liberec
