我正在学习webGL和three.js.因此,出于测试原因,我尝试创建平面几何体和两个立方体几何体以及一个点光源:

function initLights () {
    var c = context;

    var pointLight = new THREE.PointLight( 0xffffff, 1, 100 );
    pointLight.position.set( 10, 10, 10 );

    c.scene.add(pointLight);
}

function initObjects () {
    var c = context;

    /**
     * Defining the materials
     */

    var lambertRedMaterial = new THREE.MeshLambertMaterial({
            color  : 0xff0000
            , side : THREE.DoubleSide
        });

    var lambertWhiteMaterial = new THREE.MeshLambertMaterial({
            color     : 0xffffff
            , side    : THREE.DoubleSide
        });

    /**
     * Defining the floor
     */
    var floorGeometry = new THREE.Geometry();

    floorGeometry.vertices.push(new THREE.Vector3(-5.0, 0.0, -5.0)); …
