  • tinyrenderer

    A brief computer graphics / rendering course

    Latest mention: Learn 3D Computer Graphics Programming from Scratch | news.ycombinator.com | 2020-12-29

    To be fair, Handmade Hero is for a complete game with sound, effects, input, etc. This course looks to be focused on a realtime software renderer with the ability to read/write geometry and textures. HH is also a bit overwhelming.

    I think what specific tutorial might go for depends on that individual's background and goals. I know a bunch of people who work in games/vfx who use tools like Maya/Houdini every day. They don't need a lot of help learning 3d concepts, but are interested to see the pros/cons of different implementations. They aren't always interested in realtime or optimizations. Here are the free resources that normally come up:

    https://raytracing.github.io/ -- Ray Tracing in One Weekend book series

    https://github.com/ssloy/tinyrenderer/wiki -- tinyrenderer, tinyraycaster, tinyraytracer

    http://www.pbr-book.org/ -- Physically Based Rendering 3rd edition full text. It looks like a 4th edition will be published in a few months.
