Olive.c: a simple graphics library that does not have any dependencies

• olive.c

  12 1,729 4.2 C

  Simple 2D Graphics Library for C

  

From demos/triangle.c (https://github.com/tsoding/olive.c/blob/master/demos/triangl...)

    // This idea is that you can take this code and compile it to different platforms with different rendering machanisms:

• PortableGL

  7 919 9.0 C

  An implementation of OpenGL 3.x-ish in clean C

Yeah PortableGL will never be completely fully featured, not even for OpenGL 3.3 since I'll definitely never do the geometry shader and probably not the transform feedback. But specifically it'll never have the earlier immediate mode stuff, or some of the big 4.0 stuff like the tessellation shaders. I have been meaning to add the DSA functions where they make sense. They'd be really simple to implement.

Actually a few days ago someone sent me a pull request adding an interesting project to my README

https://github.com/rswinkle/PortableGL/commit/e0652b4dff266d...

So now if I were to try to sum up all the OpenGL software implementations I can think of,

TinyGL (and modern improved forks) = OpenGL 1.1-1.3 ish

• SuperSimpleGraphics

  1 6 10.0 C

  An SVG generating single header file C library appropriate for "intro to programming" classes in C/C++.

• ComputerGraphics

  1 1 10.0 C

  Basic computer graphics implementation , with linux framebuffer (by rtnF14)

Years ago, i made something similar as a coursework (Computer Graphics)

• stb

  164 25,008 6.7 C

  stb single-file public domain libraries for C/C++

There are many single-file C "libraries" that work perfectly fine as both "header" and "implementation", and that do not require unity builds (building everything as a single translation unit, e.g., a single .c file). Here is but one famous collection of them: https://github.com/nothings/stb

• Quake

  43 4,555 0.0 C

  Quake GPL Source Release

  

Also look at the source for original Quake (https://github.com/id-Software/Quake), one of the last pure software-rasterizing AAA 3D PC games. Michael Abrash's Graphics Programming Black Book (https://github.com/jagregory/abrash-black-book) explains many of the critical parts of the rendering pipeline.

By the way, quake.exe for DOS was 404,480 bytes.

• incbin

  9 909 0.0 C

  Include binary files in C/C++

won't work, since the preprocessor won't interpret directives inside string literals of course.

In many assemblers, there is a directive called "incbin" which pastes in unstructured binary data at the point of usage. I just found a very clever C and C++ wrapper [1] for that, which gives you an INCBIN() macro. Nice!
