我制作了劳力士立方体的几何形状,每层之间的“Z轴”不同。现在我想改变相机的位置,以便我可以检查几何形状正是我所期待的。我的问题是如何在拖动窗口时更改摄像机位置,还应该能够根据鼠标事件操纵每个锥体的旋转。
这是我的jsfiddle链接:http://jsfiddle.net/sagh0900/gfraQ/8/
示例代码,但请确保您访问jsfiddle以获取我的问题的详细信息:
for ( var i = 0; i <nSize; i++)
{
var k = i%10,
j = (i-k)/10;
j = j*2 - 10;
k = k*2 - 10;
var cone1 = lc_relationship.sensor1[i].Geometry;
scene.add(cone1);
var cone2 = lc_relationship.sensor2[i].Geometry;
scene.add(cone2);
var cone3 = lc_relationship.sensor3[i].Geometry;
scene.add(cone3);
cone1.position.set(j, k, lc_relationship.sensor1[i].z_cordinate);
cone2.position.set(j, k, lc_relationship.sensor2[i].z_cordinate);
cone3.position.set(j, k, lc_relationship.sensor3[i].z_cordinate);
}
如果有人可以更新我的jsfiddle或为我提供帮助就足够了。
提前致谢。

我使用空(null)网格来添加对象而不是scene:Mesh
mesh = new THREE.Mesh(new THREE.Geometry());
scene.add(mesh);
/*[...]*/
mesh.add(cone1);
/*[...]*/
mesh.add(cone2);
/*[...]*/
mesh.add(cone3);
/*[...]*/
并添加此项以旋转此网格:
var screenW = window.innerWidth;
var screenH = window.innerHeight; /*SCREEN*/
var spdx = 0, spdy = 0; mouseX = 0, mouseY = 0, mouseDown = false; /*MOUSE*/
document.addEventListener('mousemove', function(event) {
mouseX = event.clientX;
mouseY = event.clientY;
}, false);
document.body.addEventListener("mousedown", function(event) {
mouseDown = true
}, false);
document.body.addEventListener("mouseup", function(event) {
mouseDown = false
}, false);
function animate() {
spdy = (screenH / 2 - mouseY) / 40;
spdx = (screenW / 2 - mouseX) / 40;
if (mouseDown){
mesh.rotation.x = spdy;
mesh.rotation.y = spdx;
}
}
