Module voxel 

Voxel effects built on one fast mesher: smoke that rises and swirls, and drifting clouds.

Both produce a single DynamicMesh (one draw call). Hidden faces between touching voxels are never emitted, so a large cloud costs only its visible surface.

Structs

CloudVolume

Describes the density grid of a cloud layer; its key() goes into MeshRenderer.texture.

VoxelClouds

Volumetric clouds: a voxel density grid (generated from fractal noise) that the GPU ray-marches with sun scattering and self-shadowing. The entity draws only an inverted bounding box.

VoxelSmoke

Voxel smoke emitter and simulation parameters. Runtime density is not serialized.

Constants

CLOUD_VOLUME_PREFIX

Prefix for procedural three-dimensional cloud density texture keys.

Functions

mesh_grid

Meshes a voxel grid. density(x, y, z) > threshold means filled; uv.x carries the density. With shrink every voxel is scaled by its density (soft puffs, all faces emitted); otherwise full cubes are merged and faces between neighbours are culled.

mesh_grid_greedy

Merges coplanar exposed faces with equal density. Each cell is sampled once. A solid cuboid becomes six quads. Invalid parameters or >16M cells return an empty mesh.

update_clouds

Refreshes cloud proxy geometry and shader parameters; drift advances only while simulating.

update_smoke

Creates/rebuilds smoke meshes and optionally advances the density simulation by dt seconds.
