How computers draw: coordinate systems, matrices, and the rendering pipeline explained without jargon.
Computer graphics sits at the meeting point of math and images. This section starts where every drawing does: coordinate systems, the grids and spaces that say where things are, and matrices, the compact forms that move, scale, and rotate them.
From there it follows a scene through the rendering pipeline, the sequence of stages that turns a three-dimensional description into the two-dimensional image on a screen, passing through vertex processing, projection, and rasterization along the way.
The articles here explain both in plain language, with the concepts first and the implementation details second.
