each of the stages of the rendering pipeline is operating on a large set of items (vertices or fragments/pixels)

Another Quote:

These days, even if the program uses fixed-pipeline, that fixed-pipeline is simulated over shaders anyway ?

In games, more often than not, we’ll be dealing with so-called Phong reflection model.

Another Quote:

with orthographic projection, the lines which project points from our 3D world onto our 2D screen, are no longer converging to one single point; instead, they go parallel to each other.

Size-wise, textures are HUGE. Actually, in a typical 3D game, 90%+ of the space on disk (and of GPU bandwidth/RAM) are used by textures.

Another Quote:

3D anti-aliasing algorithms can be divided into two large groups: 'proper' anti-aliasing (the one which tries to avoid anti-aliasing in the first place), and 'post-processing' anti-aliasing (the one which creates an aliased image – and then post-processes it to make it look better).

Back in 80s, it was possible to calculate the speed of the program just by looking at assembly.

keep in mind that these days compilers tend to ignore inline specifications more often than not
