Mango-Kart

Implemented in C for the Mango Pi

A Mario-Kart-inspired racing game built on a custom 3D graphics engine, designed for bare metal performance on the Allwinner D1 RISC-V chip.

Technical Features

Custom 3D Graphics Engine

• Fully software-rendered 3D graphics pipeline with no hardware acceleration
• Complete vector math library with 2D/3D vector operations
• Perspective projection and camera system with view frustum culling
• Z-buffer based depth sorting for correct object rendering
• Support for wireframe and filled polygon rendering
• Real-time lighting system with face normal calculations

Game Engine Features

• Object-oriented design with support for complex 3D models
• Efficient object management with vertex, edge, and face primitives
• Dynamic camera system with smooth rotation and movement
• Custom collision detection system
• Accelerometer-based steering controls that mimic real racing wheel movement

Performance Optimizations

• Custom math implementations optimized for RISC-V architecture
• Efficient triangle rasterization with scanline algorithm
• Smart object culling and clipping against view frustum
• Fast depth sorting of rendered elements

Built as a final project for Stanford's CS107E (Computer Systems from the Ground Up) with @ethanboneh
