r3d
r3d is a 3D extension library for raylib. raylib is deliberately minimal on the 3D side, so r3d fills that gap with a proper rendering pipeline, PBR materials, dynamic lighting, and the utilities that go with them, without turning raylib into a full-blown engine.
Under the hood it’s a hybrid renderer, deferred for opaque geometry and forward for transparency, with a full PBR material system (Burley diffuse, Schlick-GGX specular), support for custom surface/sky/screen shaders, and image-based lighting via reflection probes.
On top of that there’s a decent post-processing stack (SSAO, SSGI, SSR, bloom, DoF, volumetric fog, tonemapping), frustum culling, instanced rendering, and a basic kinematics system with capsule and mesh colliders for when you need simple physics without pulling in a full physics engine.
The API stays close to raylib’s own style and conventions on purpose, so if you know raylib, r3d should feel vey familiar.
There are also r3d bindings for various languages, such as Odin, C#, and FreePascal.
