- Rocken Raster is a CPU-based Software Rasterizer designed to render 3D scenes.
- I built the Rasterizer to learn more about various Rasterizing and Graphics concepts.
- It supports many modern rendering techniques, including Triangle Rasterization, Depth Testing, Culling, Projections, Baking, and more all built from scratch.
- Rocken has a basic Audio System Implementation as well.
- The Walnut Framework is used for basic operations such as Window Creation, UI, and the GLM Math Library.
- Custom OBJ Mesh and Texture Loading
- 3D Rasterization with support for both Orthographic and Perspective projection
- Multiple Culling Techniques: Backface Culling, Depth Test Culling, and Clip Space Culling
- Scene Creation with Multiple Objects
- Camera Controls like Movement, Rotation, Panning, Zooming, and Camera Speed
- Different View Modes such as Lit, Unlit, Triangulate, Depth, and Normal
- Material System supporting both Texture-based and Color-based rendering
- Concept of Static and Movable objects
- Automatic View, Projection, & Transform Baking for Camera and Entities for Optimisations
- Exponential Fog entity that blends with the Sky Color based on Distance and Fog Falloff value
- A basic Directional Light that Illuminates meshes from the direction of Light
- User Interface tabs and buttons to Load and Configure different Scenes in Run-time
- OpenAL based Audio System with Source and Listener components
- Skeletal Animation and Skinning
- Multi-threading for faster rendering
- DLSS-like Super-Resolution
- Physically Based Rendering (PBR)
- Ray-Traced Shadows
- Improved Clip Space Culling with Retriangulation
- Particle System
- Model → World → View → Clip → NDC → UV → Pixel

Coordinate Convention (Right-Handed)
- Left → Right = +X
- Bottom → Top = +Y
- Camera → Screen = –Z
