Examples

WebGL / rectarealight


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

rectLightHelper = new v3d.RectAreaLightHelper(rectLight);
rectLight.add(rectLightHelper);
