• My notes on parallel programming from Carnegie Mellon University: notes
• For the next learning topic, see branch: dev

Logs:

In a non-chronological order, here are the logs of the development. This is what I want to explore and learn. Keep in mind that the project is still in progress and a learning exercise.

• Drawing to the screen
• Basic 3D asset
• Rendering Loop
  • CPU rasterization
  • Backface culling
  • Frustum clipping
  • Subpixel rasterization
• Lighting
  • Basic Lightnight
  • Advanced shadding
  • Ditchering to achieve shading (could be a cool background with retro look)
  • Gouraud shading
  • Phong Model
• Texture
• Camera
  • Basic FPS camera
  • Basic Look-at camera
  • Mouse input

Ressources used:

• Game Engine Architecture
• Highly recommended (demo assets from it): Pikuma's course on 3D Computer Graphics.
