computer-graphics-from-scratch VS tinyrenderer

I’m getting started too in graphics programming (web developer here) and I’ve started with the Raytracing in One Week-end, I find it to be great (I use ChatGPT along the tutorial to exchange and ask questions when I struggle). Other than that I also bought the OpenGL bible book and the book Computer Graphics from Scratch that you can both find on Amazon, they’re really great.

Computer Graphics from Scratch is fully available for free on the website, if you want to check it out first: https://gabrielgambetta.com/computer-graphics-from-scratch

It may be a bit basic compared to Abrash's but https://gabrielgambetta.com/computer-graphics-from-scratch/

Computer Graphics From Scratch is my favorite introduction to the subject. It assumes less about the reader than something like the "In A Weekend" series.

This one: https://news.ycombinator.com/item?id=19584921 And wasn't even my post!

A long time ago I found myself teaching Computer Graphics at my alma mater. Over the following years my approach to the subject evolved, and I really got the hang of it. After I stopped teaching, I took my notes, handouts and slides, and made them into a series of articles that I put on my website, where they remained in relative obscurity. Hacker News managed to find it every once in a while, and it was generally well received, but nothing came out of this. Until April 2019, when that post made the HN front page again, except this time it caught the attention of an editor in No Starch Press.

Long story short, my materials are now a book, Computer Graphics from Scratch, sold by No Starch Press [0], and also available for free on my website [1].

This genuinely wouldn’t have happened without your support. THANK YOU, HN community :)

C++: How OpenGL works: software rendering in 500 lines of code

I don’t think that exists (I sure would like for it to), but until it does you could amuse yourself with:

- A 500-line (non-OpenGL-compatible) 3D rasterizer: https://github.com/ssloy/tinyrenderer/wiki.

- A “hello Wayland” app written in C without libwayland or anything else: https://gaultier.github.io/blog/wayland_from_scratch.html.

- A “hello X11” app written in x86-64 assembly(!) without libX11, libxcb, or anything else: https://gaultier.github.io/blog/x11_x64.html.

the tinyrenderer[1] project has been on my todos forever now. glad to see the author is writing more self-paced programming projects.

- Game development - Unity3D project based learning in C#: https://learn.unity.com/ - Graphics - There was another user on r/GraphicsProgramming the other day (who teaches Computer Graphics at his university) that linked their lecture series for the entry year of their course here: https://tamats.com/learn/realtime-graphics/ - Project based learning: https://github.com/ssloy/tinyrenderer/wiki - Rendering API tutorials: https://vulkan-tutorial.com/, https://learnopengl.com/

There are a couple of excellent resources out there for implementing 3D rendering from scratch.

On that I cannot recommend enough is this github repo:

If you are more of a visual learner, this guy is also a treasure trove:

Other people have mentioned ray-tracing in one weekend

If anyone is really interested in graphics I would also recommend TinyRenderer

https://github.com/ssloy/tinyrenderer/wiki

This one is a CPU-based rasterizing renderer

Its good if you want to get a good understanding of what a GPU does underneath

I was in a similar position to you, and I first did this https://github.com/ssloy/tinyrenderer/wiki

Yes, my thoughts exactly, shader!=program on GPU. It's just a code which calculates pixel color or pixel position. See for example this: https://github.com/ssloy/tinyrenderer/blob/master/main.cpp. It's not GLSL or anything uploadable to GPU yet it's still a shader.

In terms of a project which would be worthwhile, I think building a software rasterizer from scratch is a useful first step. TinyRenderer is a great place to start. Looking at the high level overview of many graphics subjects, ScratchAPixel is a valuable resource. Theres also just great information in some of the rote graphics programming textbooks (Michael Abrash's Black Book fully available online from Jason Gregory, and this book is really interesting). The "RayTracer in a weekend" series is also (seemingly) very illuminating (no pun intended).
