是否可以隐藏框架实体的一部分？

Question

是否有相当于 CSS 的溢出：隐藏在框架中的东西？例如，我可以将一个整体限制在一个边界内，并让所有大于盒子几何形状的东西都隐藏/不可见吗？

有剪裁平面：https://threejs.org/examples/webgl_clipping.html

// ***** Clipping planes: *****
                var localPlane = new THREE.Plane( new THREE.Vector3( 0, - 1, 0 ), 0.8 );
                var globalPlane = new THREE.Plane( new THREE.Vector3( - 1, 0, 0 ), 0.1 );
                // Geometry
                var material = new THREE.MeshPhongMaterial( {
                        color: 0x80ee10,
                        shininess: 100,
                        side: THREE.DoubleSide,
                        // ***** Clipping setup (material): *****
                        clippingPlanes: [ localPlane ],
                        clipShadows: true
                    } );
                var geometry = new THREE.TorusKnotBufferGeometry( 0.4, 0.08, 95, 20 );
                object = new THREE.Mesh( geometry, material );
