PS1 Rendering: Textures, Vertices, and Draw Order
While working on Polygon Engine's renderer, I needed to understand which visual artifacts associated with PS1 came from the hardware and which could be implementation errors. Texture distortion, small jumps in vertex positions, and incorrectly ordered polygons can appear in the same scene, but they have different causes.
Separating them helped me review each stage of rendering more clearly. To explain how they relate, it helps to start with the process that turns model vertices into an image. From there, I can identify where each problem occurs and what can reduce it.
