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

PortableGL is a C library. PortableGL has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

"Because of the nature of Moore’s law, anything that an extremely clever graphics programmer can do at one point can be replicated by a merely competent programmer some number of years later." - John Carmack. In a nutshell, PortableGL is an implementation of OpenGL 3.x core in clean C99 as a single header library (in the style of the [stb libraries] It can theoretically be used with anything that takes a framebuffer/texture as input (including just writing images to disk manually or using something like stb_image_write) but all the demos use SDL2 and it currently only supports 8-bits per channel RGBA as a target (and also for textures). Obviously there are tradeoffs between several of those. An example where 4 trumps 2 (and arguably 3) is with shaders. Rather than write or include a glsl parser and have a built in compiler or interpreter, shaders are just special C functions that match a specific prototype. Uniforms are another example where 3 and 4 beat 2 because it made no sense to match the API because we can do things so much simpler by just passing a pointer to a user defined struct (see the examples).
