RectAreaLight

RectAreaLight emits light uniformly across the face a rectangular plane. This light type can be used to simulate light sources such as bright windows or strip lighting.

This light can cast shadows — see RectAreaLightShadow page for details.

Code Example


    const width = 10;
    const height = 10;
    const intensity = 1;
    const rectLight = new v3d.RectAreaLight(0xffffff, intensity,  width, height);
    rectLight.position.set(5, 5, 0);
    rectLight.lookAt(0, 0, 0);
    scene.add(rectLight)

    const rectLightHelper = new RectAreaLightHelper(rectLight);
    rectLight.add(rectLightHelper);
