ThreeJs各種集合體的快速創建

//長方體 參數：長，寬，高
var geometry = new THREE.BoxGeometry(100, 100, 100);
// 球體 參數：半徑60  經緯度細分數40,40
var geometry = new THREE.SphereGeometry(60, 40, 40);
// 圓柱  參數：圓柱面頂部、底部直徑50,50   高度100  圓周分段數
var geometry = new THREE.CylinderGeometry( 50, 50, 100, 25 );
// 正八面體
var geometry = new THREE.OctahedronGeometry(50);
// 正十二面體
var geometry = new THREE.DodecahedronGeometry(50);
// 正二十面體
var geometry = new THREE.IcosahedronGeometry(50);



// 立方體網格模型
var geometry1 = new THREE.BoxGeometry(100, 100, 100);
var material1 = new THREE.MeshLambertMaterial({
  color: 0x0000ff
}); //材質對象Material
var mesh1 = new THREE.Mesh(geometry1, material1); //網格模型對象Mesh
scene.add(mesh1); //網格模型添加到場景中

// 球體網格模型
var geometry2 = new THREE.SphereGeometry(60, 40, 40);
var material2 = new THREE.MeshLambertMaterial({
  color: 0xff00ff
});
var mesh2 = new THREE.Mesh(geometry2, material2); //網格模型對象Mesh
mesh2.translateY(120); //球體網格模型沿Y軸正方向平移120
scene.add(mesh2);

// 圓柱網格模型
var geometry3 = new THREE.CylinderGeometry(50, 50, 100, 25);
var material3 = new THREE.MeshLambertMaterial({
  color: 0xffff00
});
var mesh3 = new THREE.Mesh(geometry3, material3); //網格模型對象Mesh
// mesh3.translateX(120); //球體網格模型沿Y軸正方向平移120
mesh3.position.set(120,0,0);//設置mesh3模型對象的xyz座標爲120,0,0
scene.add(mesh3); //
