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’.
  zig build hello_rectangle-run
  

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
  zig build basic_lighting-run
