sampleImpostor

Sample the impostor as the shader would: bilinear inside a tile, bilinear across the four tiles around the requested direction.

Explained in Importing models.

function sampleImpostor(impostor: Impostor, dir: ArrayLike<number>, u: number, v: number, out: Float32Array): void

import { sampleImpostor } from '@driftengine/assets';

Parameters

Parameter	Type	Description
`impostor`	`Impostor`
`dir`	`ArrayLike<number>`
`u`	`number`
`v`	`number`
`out`	`Float32Array`

In depth

No parallax correction, which is the whole of the error between baked directions and is stated here rather than discovered: blending four flat pictures of a shape with depth ghosts it. The remedy is more directions, and it costs their square.
