Ilum Graphics Playground, name afterPlanet Ilum fromstar wars.

A framework for computer graphics learning and practice (It's not a game engine!)
bilibili: Project demo video

Platform

• Windows 10
• Visual Studio 2022
• xmake >= v2.7.5
• [optional] CUDA >= 11.7

Build

Ilum usesxmake for building. You can compile the whole project by simply run command:

xmake -y

or you can open the project in Visual Studio by generating.sln file:

xmake project -k vsxmake

• Vulkan

  • Mesh Shading
  • Dynamic Rendering
  • Ray Tracing Pipeline
  • Draw/Dispatch Indirect
  • Bindless Resource

• CUDA

  • CUDA & Vulkan Interop

• Static compilation
• Automatic resource state tracking and transition
• Texture memory aliasing
• Seamless interoperation between Graphics API and CUDA
• Easy to customize render pass

Render Pass

• Visibility Deferred Shading Pipeline

  • Visibility Geometry Pass

    • Mesh shading with meshlet frustum culling (if device supportmesh_shader)
    • Usual rasterization without optimization

  • Visibility Buffer Visualization

    • Visualize visibility buffer: instance and primitive

  • Visibility Buffer Lighting Pass

    • Indirect dispatch to support multiple material graphs
    • Generate lighting result and GBuffer

• Shadow

  • Classic Shadow Map (Spot Light)
  • Omnidirectional Shadow Map (Point Light)
  • Cascade Shadow Map (Directional Light)

• Ambient Occlusion

  • SSAO

• IBL

  • Spherical Harmonic Encoding Diffuse
  • Pre-Filter For Specular

• Ray Tracing

  • Path Tracing

• Post Process

  • Tone Mapping
  • Bloom
  • FXAA

TODO

• Resource Pool
• Runtime compilation maybe
• Multi-threading

Feature

• Static compilation and HLSL generation
• Easy to customize material node
• Support usual BSDF models

You can extend the renderer features by adding these plugins:

• RHI
• Render Pass
• Material Node
• Importer
• Editor
