Work in progress 3D game engine with Rust and wgpu.

^ drawing 10k lamp posts at 70fps; 53m triangles per frame / 3.8b per second

Features

• skeletal animation
  • animation evaluation jobs executed on worker threads
  • simple anim graph with states/transitions + blending
  • no root movement, blend masks, events, etc...
  • animating submeshes that aren't part of a skeleton is planned
• asset streaming
  • separate io worker pool
  • refcounted handles owned by game thread
  • eviction not yet implemented
• gltf import
  • .gltf and .glb files
  • primitive
    • mode (primitive topology) missing
      • winding order
    • targets (morph targets) missing
    • primitive attributes
      • only one each of JOINTS and WEIGHTS supported
      • no vertex colors
  • node
    • cameras, lights not planned
  • scene: only renders the root scene
  • extensions: no extensions planned
• importing equirectangular .hdr radiance maps (projected onto a rgba16f cubemap)
• baking mipmaps
• textures using dds with block compression
• screen space skyboxes
• physically based rendering (PBR) along with image based lighting (IBL)
  • analytical lights: just directional for now
  • image based diffuse irradiance
  • split sum specular approximation (prefiltered env map calculated at import time, BRDF LUT read from a png)
• normal mapping (with world-space lighting)
• HDR (needs some improvement with physical units)
• 4x MSAA
• some basic camera movements for looking around with lmb drag and scroll
