K0bin / SourceRenderer

A tiny 3D engine that loads and renders Source engine maps - Also known as dreieck.exe

SourceRenderer

Source Engine map renderer written in Rust

It's a Rust port of https://github.com/K0bin/sourceloader and I plan to add a Vulkan renderer. The main goal of this project is to learn Rust and Vulkan.

Features:

• rather basic Vulkan forward renderer
  • temporal anti aliasing
  • SSAO
  • clustered forward shading (currently only supports point lights)
  • incomplete PBR lighting
  • Two render paths:
    • Conservative:
      • Frustum culling & occlusion culling (based on GPU queries)
    • GPU driven:
      • frustum culling in compute
      • occlusion culling in compute using a hierarchical z-buffer
      • bindless textures
  • Vulkan ray tracing
    • Soft shadows (denoising is still TODO)
  • Late latching just before submission to minimize latency
  • Texture streaming using a transfer queue
• Pipelined rendering
• loading Source engine maps:
  • loading BSP levels
    • basic brush geometry
    • displacements (at least to some degree)
    • light maps
    • static models
  • loading 2D VTF textures
  • loading the most basic VMT materials
• loading GLTF levels (currently without textures and needs to be rewritten to use less memory)

Platforms:

• Desktop
  • using SDL2
  • tested on Linux & Windows
  • shouldn't take too much work to make it work on Mac OS
• Web version
  • using web workers & SharedArrayBuffers for threading
  • extremely limited WebGL2 renderer
• Android version
  • used the Vulkan renderer
  • using Khronos Vulkan extension layers to support timeline semaphores and synchronization2 on older drivers
