A small C++/OpenGL 3D renderer. It loads glTF models (converted from GameCube BMD assets), plays back skeletal animations, and renders them with shadow mapping, a sky pass, and a lens flare effect. Includes a free-fly camera and support for scripted cutscenes (STB format).

Features

• glTF model loading with skeletal (skinned) and static mesh support
• Shadow mapping
• Sky rendering with a lens flare pass
• Cutscene playback and animation remapping (STB format)
• Free-fly camera with mouse look and WASD movement

Requirements

• CMake 3.10+
• A C++23 compiler
• GLFW 3.3+
• OpenGL
• GLM

glad, tinygltf, stb_image, and json.hpp are bundled under ext/.

Build

mkdir build
cd build
cmake ..
make

Run

Run the resulting binary from the repository root, so the relative paths to shaders/ and res/ resolve correctly:

./build/main

Project structure

src/       renderer source (camera, scene, models, animations, shaders, textures, input)
shaders/   GLSL shaders (mesh, shadow, sky, lens flare)
res/       models, textures, and cutscene data
ext/       bundled third-party headers (glad, tinygltf, stb_image, json)

Notes

Model and texture assets under res/ come from external sources and are not original work. This project is a rendering exercise, not a released application, and has no installer or packaged build.
