What algorithms are embedded in the opengl function?

Question

C++ / C#

There was an urgent need to describe the algorithms of the functions perspective, stencilfunc, stencilop, clipplane and some others (not a brief description of the function or user instructions, but the algorithm implemented in this or that function. The source code would be a salvation). Please suggest some resource.

Answer 1

There is such a library as glm . She can do everything that OpenGL can (in terms of mathematics) and be distributed through source codes.

Answer 2

Some information can be found here - a short course in computer graphics.

Answer 3

Do you do reverse? What for? Take the book "Mathematical Foundations of Computer Graphics", immediately many questions disappear, further in ascending order. For info on stencilfunc, stencilop look for "stencil buffer", and even here Google gives pretty good results.
