我遇到了一个问题,我怎样才能获得一种像圆环一样的“开环”? 我尝试了一个形状加一条路径作为一个洞:
var arcShape = new THREE.Shape();
arcShape.moveTo( 40, 0 );
arcShape.arc( 0, 0, 40, 0, 2*Math.PI, false );
var holePath = new THREE.Path();
holePath.moveTo( 30,0 )
holePath.arc( 0, 0, 30, 0, 2*Math.PI, true );
直到现在,制作一个网格:
new THREE.Mesh( arcShape.extrude({ amount: 5, bevelEnabled: false }), MATERIAL );
它有效,但如何制作中环?我的意思是:
var arcShape = new THREE.Shape();
arcShape.moveTo( 40, 0 );
arcShape.arc( 0, 0, 40, 0, Math.PI, false );
var holePath = new THREE.Path();
holePath.moveTo( 30,0 );
holePath.arc( 0, 0, 30, 0, Math.PI, true );
它有效,但它仍然是终端部件之间的微妙面孔......有没有办法让它完全打开?

尝试更改Torus几何构造函数中的参数,而不是从方形一开始:
// Torus geometry parameters:
// radius of entire torus,
// diameter of tube (should be less than total radius),
// segments around radius,
// segments around torus ("sides")
var torusGeom = new THREE.TorusGeometry( 25, 10, 4, 4 );
