DAGger: Sparse Voxel DAG Rendering on the Web

Try it out!

This is a web version of the viewer application from my SVDAG-Compression repository, which originates from the source code released alongside the SSVDAG paper.

Goals

  • Render Sparse Voxel DAG in the browser using WebGL. Changes from OpenGL implementation: Replaced SamplerBuffer with Texture3D for represesenting nodes (no support in WebGL).
  • Beam optimization: A low-res depth pre-pass for starting off primary visibility rays close to the geometry they will hit. The beams are 8 by 8 pixel blocks.
  • First person controller [wip]
  • Stream the data to the GPU while downloading [wip]
  • Fractal generator [wip]
  • Path tracing: Implementation based on Alan Wolfe's blogpost
  • CPU raycasting for collision detection (gravity) and scene interaction (cursor rays) [wip]
  • Attribute encoding (colors)
  • Import 3D models (voxelize on the fly)
  • Scene modification
  • Stream based on demand - only nodes that are visible or close to the camera (e.g. could separate scene into a root file and 64 "chunk" files)

Running it locally:

  • Get NPM and Yarn installed
  • Install dependencies with yarn install
  • Running yarn start will compile TypeScript to JavaScript and start up an http server
