Class GiRadiusDemo

java.lang.Object
eu.svjatoslav.aukio.e3d.examples.gi_radius_demo.GiRadiusDemo
public class GiRadiusDemo extends Object
Radius-gated GI showcase: a 48 000-unit procedural tower district stored as lean TriangleMeshBlocks (the same geometry kind streaming game worlds use). Without radius gating the bake would grind the whole district forever; with e3d.giStage2Radius / giStage3Radius / giStage4Radius set (config.yaml or -D), the light bubble around the camera gets centroid bounce, then coarse lightmaps, then fine lightmaps — and the bubble follows as you fly (WASD + mouse drag; the catch-up watcher re-lights what you approach).

GI uses district-scale per-instance radius overrides (stage 2/3/4 = 24 000 / 10 000 / 5 000 units, mesh texel = 50 units) — the shared config.yaml values are FO4-scale (meters), far too small for this 48 000-unit district. An explicit -De3d.gi.stage*Radius / -De3d.gi.meshUnitsPerTexel flag still wins over the demo defaults.

The golden path (buildScene(ShapeCollection, LightingManager, Camera)) is GI-free and fully deterministic (seeded heights and textures).
