Voxler, a voxel world that computes itself as you fly

Field notes

The engine generates terrain from two WGSL functions while the visitor moves through it, retaining only the surrounding area rather than loading a complete level. Voxler combines block rendering nearby with ray tracing through a coarser copy at distance; the page says this supports worlds extending 33 million voxels from the centre to the edge. A runnable, editable example and Apache 2.0 source are linked from the public page.
