cool engine

Toy engine + Vulkan renderer I built for fun to learn Odin language (and some graphics techniques).

Features

• Fully written by hand (Fuck off Claude). Wow so special.
• Sparse entity system (ECS-like)
• First person player controller based on Unreal character movement
• Skeletal meshes and animation
• Bindless System (see shaders/tonemapping.slang for a simple example!)
• • Bindless versions of Texture*, SamplerState and SamplerComparisonState, while keeping the usage the same.
• • Buffers use BDA
• Metaprogram to generate assets tables and shader glue code
• glTF loading of meshes and skeletal meshes
• Physics (with Box3D, vendored in Odin)

Renderer Features

• DDGI (requires hardware raytracing)
• Parallax-Corrected Cubemaps
• PBR + IBL + HDR based on Filament
• Point lights
• Tonemapping (tony-mc-mapface)
• Very Crude Text Rendering
• CSM
• Compute skinning

How to build:

1. Clone repo
2. Run git submodule update --init --recursive to get submodules.
3. Run build.bat to generate build/debug/main.exe. Or build.bat 1 to generate a release build in build/release/main.exe.
