After the eye coordinates are transformed by multiplying GL_PROJECTION matrix, the clip coordinates are still a homogeneous coordinates. It finally becomes the normalized device coordinates (NDC) by divided by the w-component of the clip coordinates.

One important thing to realize is that matrix multiplications are in a sense, additive. For example, if you take a matrix that starts with the identity matrix, multiply it times a rotation matrix, then multiply it times a scaling matrix, you end up with a matrix that ...

WebJust like the graphics pipeline, transforming a vector is done step-by-step. Although OpenGL allows you to decide on these steps yourself, all 3D graphics applications use a variation of the process described here. Each transformation transforms a vector into a new coordinate system, thus moving to the next step. sight of the sun sheet musicWebThis convention was established for OpenGL and first realized in the OpenGL Utility Library (GLU).
