A demo application implementing physically based shading and image based lighting in four graphics APIs: OpenGL 4.5, Vulkan, Direct3D 11, and Direct3D 12. Each API implementation is self-contained and heavily commented, intended as a side-by-side educational comparison of modern graphics APIs.

Use cases

• learn physically based rendering techniques
• compare Vulkan vs Direct3D vs OpenGL implementations
• study Cook-Torrance BRDF and image based lighting code
• see how compute shaders filter environment maps
• reference example for writing a PBR shader
• learn modern graphics API usage with a non-trivial demo

When to choose

• you want commented, minimal reference code for PBR and IBL
• you want to compare the same renderer written across four graphics APIs
• you are learning Vulkan, D3D11/12, or OpenGL 4.5 with a concrete example

When to avoid

• you need a production-ready or optimized rendering engine
• you need macOS support
• you need an actively maintained project with recent updates
