OskarGroth / MetalGraphicsPlayground

Personal test project using Metal (Mac)

MetalGraphicsPlayground

This workspace contains subprojects for testing Metal features. Requires Xcode 11 or later.

Rendering Engine (work in progress)

MetalDeferred, MetalPostProcessing and MetalSceneGraph use deferred rendering based PBR frameworks. You can check framework sources codes in Common directory!

    • Light culling pass
    • Shade pass : Convolution
• Image based Lighting
  • HDRI Image (Equirectangular map -> Cubemap)
  • Split-sum approximation model
• Physically based Rendering
  • Metalic, Roughness, Anisotropic
• Light
