WasmGPU.createLight.point¶

Summary¶

WasmGPU.createLight.point creates a PointLight with local position and range controls. Point lights are useful for probes, local highlights, and instrument-like emitters. Combine position, intensity, and range to shape localized illumination without flattening global contrast.

Syntax¶

WasmGPU.createLight.point(options?: PointLightOptions): PointLight
const light = wgpu.createLight.point(options);

Parameters¶

Name	Type	Required	Description
`options`	`PointLightOptions`	No	Optional point-source position/color/intensity/range configuration.

Returns¶

PointLight - Point light object ready for scene.addLight(light).

Type Details¶

Color¶

type Color = [number, number, number];

PointLightOptions¶

type PointLightOptions = {
    position?: [number, number, number];
    color?: Color;
    intensity?: number;
    range?: number;
};

PointLightOptions Fields¶

Name	Type	Required	Description
`position`	`[number, number, number]`	No	World-space source position; default `[0, 0, 0]`.
`color`	`Color`	No	Normalized RGB light color; default `[1, 1, 1]`.
`intensity`	`number`	No	Brightness multiplier; default `1`.
`range`	`number`	No	Effective attenuation distance; default `10`.

Example¶

const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);

const scene = wgpu.createScene();
const probeLight = wgpu.createLight.point({
    position: [2, 1.5, -0.5],
    color: [0.8, 0.95, 1.0],
    intensity: 2.2,
    range: 18
});
scene.addLight(probeLight);
