Voxel engine using WebGPU. The same codebase runs as a native SDL3 app or in the browser via WASM.
Online demo: https://dawdmaow.github.io/wgpuvoxels/
- terrain generation using GPU compute shaders
- dig/place voxels
- UI hotbar selection for different voxel types
- water and swimming
- falling sand
- TNT explosions
- rain shader
- layered clouds (2.5D)
- planar water reflections
- post-processing (bloom, depth of field, underwater distortion, fog)
