Learn OpenGL using Zig.

Windowing library: mach/glfw - Ziggified GLFW bindings by slimsag (Stephen Gutekanst).

OpenGL bindings for Zig were generated by the zig-opengl project by MasterQ32 (Felix Queißner).

zstbi - stb image bindings, zmath - SIMD math library, provided by Michal Ziulek, part of the zig-gamedev project.

Sample programs can be used together with the reference book: Learn OpenGL - Graphics Programming by Joey de Vries.

Zig Language installation How-to instructions.

I. Getting Started

Hello Triangle

hello_triangle: Minimal setup for drawing a trianlge on screen.
zig build hello_triangle-run
hello_rectangle: Draw a rectangle efficiently with indexed rendering using the 'Element Buffer Object'.

Shaders

shaders: Little programs that rest on the GPU
zig build shaders-run

Shader struct mirrors the C++ Shader Class in the book.

Textures

textures: Decorate objects with textures
zig build textures-run

Transformations

Transformations: Apply a transformation matrix to vertex data
zig build transformations-run

Coordinate Systems

Coordinate systems: Model, View, Projection matrices
zig build coordinate_systems-run

Camera

Camera rotation: Camera rotation around world origin
zig build camera_rotate-run
Simple camera: Fly-like camera
zig build simple_camera-run

II. Lighting

Basic Lighting

Basic Lighting: Phong lighting model
