encodeTerrainSplat

Encode four material weights per sample.

Explained in Terrain.

function encodeTerrainSplat(width: number, depth: number, weights: ArrayLike<number>): TerrainSplatLayer

import { encodeTerrainSplat } from '@driftengine/terrain';

Parameters

Parameter	Type	Description
`width`	`number`
`depth`	`number`
`weights`	`ArrayLike<number>`

In depth

Refuses a map whose weights do not already sum to one, rather than normalising it on the way in. A weight map nobody filled in sums to zero at every texel, and a normalisation applied quietly turns that into "material zero, everywhere" — a whole world of one texture, shipped, with no error anywhere. The caller's own weights are a statement about the ground and this does not edit it.
