我使用xyz点列表画了一行,如下所示
for (var i = 0, len = vertices.length - 1; i < len; i++) {
vertex = vertices[i];
geometry = new THREE.CubeGeometry(width+7, height, 1);
geometry.computeVertexNormals();
//material = new THREE.MeshBasicMaterial({ color: 0xff3333, shading: THREE.FlatShading, wireframe: true, transparent: true });
//Initializing MeshNormalMaterial to get the 3d Line Geometry
material = new THREE.MeshBasicMaterial({ color: 0xEB9180 });
mesh = new THREE.Mesh(geometry, material);
mesh.position = vertex;
mesh.lookAt(vertices[1 + i]);
length = vertex.distanceTo(vertices[1 + i]);
mesh.scale.set(1, 1, length + width);
mesh.translateZ(0.5 * length);
segments.add(mesh);
}
使用xyz点列表动态创建的行:
现在我想在行上放置一个图像图标,该图标应遍历整行,如下所示
答案 0 :(得分:0)
我建议您使用THREE.Sprite()
对象作为图标。你可以给它一个纹理。
至于沿着线移动它,只需调整Sprite的.position
值以跟随顶点数组。我把速度管理留给你了!
