Show HN: Capsule introduction to wireframe 3d rendering
- mjn 14y agoThis is a tutorial I made for a class I teach. I wasn't entirely happy with the existing online materials (e.g. Wikipedia's treatment is a bit scattered), and graphics textbooks typically do a thorough but quite in-depth job. I wanted something that was concise and completely self-contained, so someone could implement a wireframe renderer in software completely from scratch using it. The main compromise is that some of the derivations are therefore left out, e.g. the perspective transform matrix is motivated conceptually, but then simply given. Clearly it could be improved with diagrams, and perhaps an HTML5 Canvas demo. Just haven't had a chance to add those yet. Other kinds of feedback that could improve the exposition are welcome!
