javascript - 如何获得立方体的宽度和高度？

Question

我有一个立方体几何体和一个网格，但我不知道如何获取宽度。这是代码:

geometry = new THREE.CubeGeometry( 200, 200, 200 );
material = new THREE.MeshBasicMaterial( { color: 0xff0000, wireframe: true } );
mesh = new THREE.Mesh( geometry, material );

Answer 1

您可以使用scale来代替。

geometry = new THREE.CubeGeometry( 1, 1, 1 );
material = new THREE.MeshBasicMaterial( { color: 0xff0000, wireframe: true } );
mesh = new THREE.Mesh( geometry, material );
mesh.scale.x = 200;
mesh.scale.y = 200;
mesh.scale.z = 200;
