1. Demonstrator
interactive signed distance field scene
The jumping yellow creature, terrain and candy shapes are built from SDF primitives combined into a single distance field and rendered with raymarching.
Drag to orbit the camera. Use the mouse wheel — or pinch — to zoom.
Just a happy yellow creature
2. What is an SDF?
signed distance field
A Signed Distance Field is a function that reports how far a point in space is from the surface of an object. Its sign distinguishes the spatial state:
- Negative — inside the object.
- Zero — exactly on the surface.
- Positive — outside the object.
3. Key Advantages
compact procedural geometry
- Compact, mathematics-based scene descriptions.
- Smooth blending between primitives.
- Resolution-independent geometry without conventional meshes.
