software rasterizer 📐

A compact C++20 learning project inspired by ssloy’s tinyrenderer. It implements a CPU rasterization pipeline with a simple TGA image backend and utilities for drawing, loading models, and writing output images. Ideal for experimenting with fundamentals (lines, projections, faces) before scaling to a fuller renderer.

Run

Requirements

• CMake 3.24+
• A C++20 compiler

Build and run with these commands:

cmake -S . -B build -G "Ninja"
cmake --build build

# Choose an .obj file to render
./build/rasterizer obj/{file}.obj        # Linux/macOS
./build/rasterizer.exe obj/{file}.obj    # Windows

Output images are written to assets/output.tga by default.
