Webtracer

• A pathtracer written in rust - runs in the web and includes an editor
• Rendering is parallelized and utilizes all cpu cores
• You can easily edit scenes and move the camera (see how to use)
• Based on Ray Tracing in One Weekend tutorial series - supports spheres, bricks, lights, image-based textures...
  • note: images, due to DOM weirdness, have to be baked into the binary, so if you want to add your custom images, you'll have to rebuild the project (feel free to message me how to do so)
• Try out the live demo: Live Demo

Run the build script - rust and wasm-pack are requiered Use a static file server like sfz to host.
