Java Swing Orthographic Renderer

Overview

An orthographic 3D renderer built from scratch in Java Swing with a custom rasterization pipeline. Supports textured .obj meshes and implements performance-focused optimizations such as bounding box rasterization, z-buffering for proper depth handling, and double-buffering for smooth frame updates. Designed as a learning project to explore the fundamentals of computer graphics without external engines.

Key Features

• •Orthographic projection rendering pipeline
• •Triangular .obj mesh support with textures
• •Bounding box rasterization for faster triangle fills
• •Z-buffer implementation for correct depth rendering
• •Buffered drawing for smooth display updates
• •Sample icosahedron model included
