World-space fog motes in a Three.js corridor

A restrained corridor effect is a useful place to inspect the difference between world-space particles and a screen overlay. This deck proposes a small Three.js fixture with a bounded emitter, opaque depth occluders, and an explicit cleanup check. It explains what to inspect while the camera moves, why transparent surfaces need separate review, and which measurements belong in a target-device performance check.

The example uses a three js particle editor workflow, but does not treat an editor preview as proof of runtime behavior. The NixieFX Three.js runtime guide (https://nixiefx.com/threejs-runtime/) is the reference for the particle adapter. The local receipt covers simulation occupancy, completion, and unsupported-feature reporting. It does not measure GPU overdraw, mobile frame time, or volumetric lighting. The deck uses a procedural scene and makes no claim about production footage or user testing.
