我有这个在2点之间创建一条线：
- var geometry = new THREE.Geometry();
- geometry.vertices.push(new THREE.Vector3(0,0));
- geometry.vertices.push(new THREE.Vector3(20,100,55));
- var line = new THREE.Line(geometry,material,parameters = { linewidth: 400 });
- scene.add(line);
(线宽,没有任何影响.)
我的问题是如何将其转换为圆柱体？我想在两点之间创建一个圆柱体.
解决方法
我有完全相同的问题 – 在WebGL中,线宽总是1.所以这是我写的一个函数,它将采用两个Vector3对象并生成一个圆柱网格：
- var cylinderMesh = function( pointX,pointY )
- {
- // edge from X to Y
- var direction = new THREE.Vector3().subVectors( pointY,pointX );
- var arrow = new THREE.ArrowHelper( direction,pointX );
- // cylinder: radiusAtTop,radiusAtBottom,// height,radiusSegments,heightSegments
- var edgeGeometry = new THREE.CylinderGeometry( 2,2,direction.length(),6,4 );
- var edge = new THREE.Mesh( edgeGeometry,new THREE.MeshBasicMaterial( { color: 0x0000ff } ) );
- edge.rotation = arrow.rotation.clone();
- edge.position = new THREE.Vector3().addVectors( pointX,direction.multiplyScalar(0.5) );
- return edge;
- }
