warpedPoint
A 3D position pushed around by moving noise, for reading several fields at one warped spot.
warpedPoint(opts: {at: Expr; time: Expr | number; amount: Expr | number; levels?: 1 | 2}): Expr
Import paint from shaders/std and use paint.warpedPoint.
at is the 3D point to warp, time drives the motion, amount how far it is pushed. levels 2 (default) is the full warp, 1 is a cheaper single pass for low-power devices. Use warped instead when one field is enough.
Parameters
| Name | Type | Notes |
|---|---|---|
opts | {at: Expr; time: Expr | number; amount: Expr | number; levels?: 1 | 2} |
Example
const q = warpedPoint({at: math.vec3(x, y, seed), time: math.mul(t, 0.3), amount: 0.5, levels: isMobileGpuViewport() ? 1 : 2})
