LOD对象,LOD技术即Levels of Detail的简称,意为多细节层次。LOD技术指根据物体模型的节点在显示环境中所处的位置和重要度,决定物体渲染的资源分配,降低非重要物体的面数和细节度,从而获得高效率的渲染运算。

Line对象,创建一条线,或者一组线.
用法:var geometry = new THREE.Geometry(); //创建geometry对象
var material = new THREE.LineBasicMaterial({color: 0xffff00}); //创建材质对象,这里有专门适用于line对象的材质对象LineBasicMaterial.
geometry.verteces.push(new THREE.Vector3(-10,0,0), //为geome...

Mesh对象,最终的网格对象,有高人把图形学建模比作是制作灯笼,先用Geometry创建灯笼的框架,然后将材质material贴在框架上,最后形成的总体灯笼,就是Mesh对象.下面看一下Mesh对象的用法和具体实现.
用法:var geometry = new THREE.Geometry(1,1,1); //创建geometry对象(灯笼的框架),
//有一下可选对象BoxGeometry,CircleGeometry,CubeGeometry,CylinderGe...
