Methods

withPoints

withPoints(num: number): this
Set the number of points
Parameters
- num: number
Returns this
- Defined in src/tests/builders/test-data-builders.ts:42

withDimensions

withDimensions(dims: number): this
Set the number of dimensions
Parameters
- dims: number
Returns this
- Defined in src/tests/builders/test-data-builders.ts:50

withPositions

withPositions(positions: number[] | Float32Array<ArrayBufferLike>): this
Add specific positions
Parameters
- positions: number[] | Float32Array<ArrayBufferLike>
Returns this
- Defined in src/tests/builders/test-data-builders.ts:58

withRandomPositions

withRandomPositions(range?: [number, number]): this
Generate random positions
Parameters
- range: [number, number] = ...
Returns this
- Defined in src/tests/builders/test-data-builders.ts:66

withColors

withColors(colors?: number[] | Float32Array<ArrayBufferLike>): this
Add colors (random if not specified)
Parameters
- Optionalcolors: number[] | Float32Array<ArrayBufferLike>
Returns this
- Defined in src/tests/builders/test-data-builders.ts:79

withRadii

withRadii(radius: number | number[] | Float32Array<ArrayBufferLike>): this
Set radii.

Accepts either:
- a scalar (number) — broadcast to every point, OR
- an explicit Float32Array / number[] of length numPoints — cloned into a fresh Float32Array so the builder owns its own buffer (a later mutation by the caller cannot leak in).
Mismatched-length arrays throw a clear error rather than silently truncating or zero-extending.
Parameters
- radius: number | number[] | Float32Array<ArrayBufferLike>
Returns this
- Defined in src/tests/builders/test-data-builders.ts:104

withVaryingRadii

withVaryingRadii(min?: number, max?: number): this
Add varying radii
Parameters
- min: number = 0.1
- max: number = 1.0
Returns this
- Defined in src/tests/builders/test-data-builders.ts:121

withSharpness

withSharpness(value?: number): this
Add sharpness values
Parameters
- value: number = 2.0
Returns this
- Defined in src/tests/builders/test-data-builders.ts:132
