Zig Learn OpenGL

Learn OpenGL tutorials ported to the zig programming language. This repo follows the chronological order of the website, separating out the same functionality into separate files. The repository is intended to serve as a demonstration of how to use OpenGL with zig, both in user code, and with the zig build system.

Currently the "Getting Started" and "Lighting" sections have been ported in full, and I've also ported the ibl specular implementation in the PBR section for a bit of eyecandy.

Dependencies

• GLAD (vendored)
• STB (vendored)
• GLFW (byo)

All dependencies except for GLFW are vendored under deps/. For GLFW, install using your OS package manager, or if using windows, install using something like vcpkg and edit the paths in build.zig.

Running

Check build.zig for the full list of implemented stages, to run the relevant stage, just run its zig build command, for example:

zig build hello_triangle    # Renders a colorful triangle
zig build camera            # Renders a scene with many boxes and a camera
zig build multiple_lights   # Renders the same scene but with diffuse/specular maps and multiple lights

Stability

My intention is to keep this repo up to date with the language. This has been tested and works with:

• 0.5.0+d972d1c94
