Class LinesBuilder

Builder for lines test data.

Mirrors the PointsBuilder API: chained withX() setters and a final build() that returns plain typed arrays + counts. Use this in spatial-index loader, projection, and clipping tests so the test fixtures stay consistent across geometry types.

Example

const lines = new LinesBuilder()
  .withSegments(50)
  .withDimensions(3)
  .withRandomVertices()
  .withWidths(1.0)
  .build();

Methods

withSegments

withSegments(num: number): this
Set the number of line segments.
Parameters
- num: number
Returns this
- Defined in src/tests/builders/test-data-builders.ts:198

withDimensions

withDimensions(dims: number): this
Set the number of spatial dimensions.
Parameters
- dims: number
Returns this
- Defined in src/tests/builders/test-data-builders.ts:204

withVertices

withVertices(vertices: number[] | Float32Array<ArrayBufferLike>): this
Provide explicit vertex data ((numSegments * 2) * dimensions floats).
Parameters
- vertices: number[] | Float32Array<ArrayBufferLike>
Returns this
- Defined in src/tests/builders/test-data-builders.ts:210

withRandomVertices

withRandomVertices(range?: [number, number]): this
Generate random vertex data within range.
Parameters
- range: [number, number] = ...
Returns this
- Defined in src/tests/builders/test-data-builders.ts:216

withWidths

withWidths(width: number): this
Set uniform widths.
Parameters
- width: number
Returns this
- Defined in src/tests/builders/test-data-builders.ts:227

withVaryingWidths

withVaryingWidths(min?: number, max?: number): this
Set varying widths.
Parameters
- min: number = 0.1
- max: number = 1.0
Returns this
- Defined in src/tests/builders/test-data-builders.ts:233

withSegmentIndices

withSegmentIndices(segments: number[] | Uint32Array<ArrayBufferLike>): this
Provide explicit segment indices. If omitted, auto-generates the canonical [0, 1, 2, 3, ..., 2N-1] packing where each segment takes two consecutive vertex indices.
Parameters
- segments: number[] | Uint32Array<ArrayBufferLike>
Returns this
- Defined in src/tests/builders/test-data-builders.ts:246

withColors

withColors(colors?: number[] | Float32Array<ArrayBufferLike>): this
Add per-vertex colors as RGB floats. Random when no values are passed.
Parameters
- Optionalcolors: number[] | Float32Array<ArrayBufferLike>
Returns this
- Defined in src/tests/builders/test-data-builders.ts:252

withSharpness

withSharpness(value?: number): this
Per-vertex sharpness scalars.
Parameters
- value: number = 2.0
Returns this
- Defined in src/tests/builders/test-data-builders.ts:265

build

build(): {
    vertices: Float32Array;
    widths: Float32Array;
    segments: Uint32Array;
    colors: Float32Array<ArrayBufferLike>
    | null;
    sharpness: Float32Array<ArrayBufferLike> | null;
    numSegments: number;
    dimensions: number;
}
Build the test fixture. vertices is auto-populated with random values if no withVertices/withRandomVertices call preceded build(). widths defaults to a uniform 1.0 if unset (required attribute). segments defaults to the canonical packing if unset.

Returns {
    vertices: Float32Array;
    widths: Float32Array;
    segments: Uint32Array;
    colors: Float32Array<ArrayBufferLike> | null;
    sharpness: Float32Array<ArrayBufferLike> | null;
    numSegments: number;
    dimensions: number;
}
