widgets Component – <Sampler>

const Sampler: LiveComponent<SamplerProps<string | string[]>>

Up-to-4D array of a WGSL type. Samples a given expr on the given range.

Props

number[]

Sample count up to [width, height, depth, layers]

number

Shorthand for size=[length]

string

Axis to sample on (1D)

string

Axes to sample on (2D+)

VectorLike

Sample origin to maintain alignment to

string

WGSL type per sample

Emitter

Input emitter expression

([number, number])[]

Input range to sample on each axis. Use RangeContext if omitted.

number

Extra padding samples to add outside the input range.

number

Emit N items per expr call. Output size is [items, ...size] if > 1.

boolean

Emit 0 or N items per expr call. Output size is [N] or [items, N].

boolean[] | boolean

Use centered samples (0.5, 1.5, ..., N-0.5) instead of edge-to-edge samples (0, 1, ..., N).

boolean

Add current indices i, j, k, l to the expr arguments.

boolean

Add current TimeContext to the expr arguments.

boolean

Resample data or expr on every animation frame.
