实际生活中物体表面的明暗效果是会受到光照的影响,比如晚上不开灯,你就看不到物体,灯光比较暗,物体也比较暗。在threejs中,咱们用网格模型Mesh模拟生活中物体,所以threejs中模拟光照Light对物体表面的影响,就是模拟光照Light对网格模型Mesh表面的影响。 在Three.js 提供的材质里面,有可以受光照影响的材质,有不受光照影...
Three.js 提供了 WebGLRenderer 和 CanvasRenderer 两种渲染器,其中 WebGLRenderer 利用 WebGL 技术实现硬件加速渲染,性能更好。 光源(Light):光源用于模拟场景中的光照效果。Three.js 支持多种类型的光源,包括环境光、点光源、聚光灯和方向光等,通过调整光源的参数可以控制阴影、反射等效果。 材质(Material):材质定...
