Features

Graphics

• Render graph system
• Progressive stochastic path tracing
• Importance sampling of BSDFs and multiple importance sampling of lights
• Lambertian, Mirror, Glass, and Disney BSDFs
• Point and quad lights
• Real-time path tracing using both DXR 1.0 and DXR 1.1

D3D12

• Bindless resource
• Asynchronous PSO compilation using coroutines and threadpools
• Utilization of graphics and asynchronous compute queues
• Acceleration structure compaction using modified RTXMU

Misc

• Custom scene serialization using json
• Custom binary format for loading meshes and meshlets
• Asynchronous asset importing using threads
• Asset management using lightweight handles

World

• Ecs with the following implemented components:
  • Core: Main component that all actor in the scene have, it contains tag that identifies the actor and a transform which controls position, scale, and orientation
  • Camera: controls camera parameters for scene viewing
  • Light: used to illuminate the scene, controls light parameters
    • Supported types:
      • Point
      • Quad
  • Static Mesh: references a mesh in the asset window to be rendered and controls material parameters and submits the referenced mesh to RaytracingAccelerationStructure for path tracing
    • Supported BSDFs:
      • Lambertian
      • Mirror
      • Glass
      • Disney
  • NativeScript: C++ scripting
