The Dicee Game

Problem

Ray marching with signed distance functions (SDFs) is a powerful technique for rendering implicit surfaces that can’t be trivially rasterised. The challenge was building a compelling, interactive demo that runs at 60 FPS in the browser with no native plugins.

Approach

All geometry is defined analytically via SDFs in a GLSL fragment shader. Soft shadows are computed with secondary ray marches; ambient occlusion is estimated from nearby SDF samples. Procedural terrain uses layered domain-warped noise functions.

Results

Feature	Detail
FPS (Chrome, RTX 3080)	60
FPS (Chrome, integrated GPU)	30–45
Geometry	100% SDF-based
Shader LOC	~350

Fully interactive: mouse controls camera, scroll adjusts fog density.
