copied!<p>[edit] Three cylinders didn't work since the cap UVs are bogus. You need to roll your own cap geometries. Not a lot of work, just annoying. Here's how to do an uncapped cylinder with custom caps:</p> <pre><code>var coin_sides_geo = new THREE.CylinderGeometry( 10.0, 10.0, 1.0, 100.0, 10.0, true ); var coin_cap_geo = new THREE.Geometry(); var r = 10.0; for (var i=0; i<100; i++) { var a = i * 1/100 * Math.PI * 2; var z = Math.sin(a); var x = Math.cos(a); var a1 = (i+1) * 1/100 * Math.PI * 2; var z1 = Math.sin(a1); var x1 = Math.cos(a1); coin_cap_geo.vertices.push( new THREE.Vertex(new THREE.Vector3(0, 0, 0)), new THREE.Vertex(new THREE.Vector3(x*r, 0, z*r)), new THREE.Vertex(new THREE.Vector3(x1*r, 0, z1*r)) ); coin_cap_geo.faceVertexUvs[0].push([ new THREE.UV(0.5, 0.5), new THREE.UV(x/2+0.5, z/2+0.5), new THREE.UV(x1/2+0.5, z1/2+0.5) ]); coin_cap_geo.faces.push(new THREE.Face3(i*3, i*3+1, i*3+2)); } coin_cap_geo.computeCentroids(); coin_cap_geo.computeFaceNormals(); var coin_sides_texture = THREE.ImageUtils.loadTexture("./coin_sides.png"); var coin_cap_texture = THREE.ImageUtils.loadTexture("./coin_face.png"); var coin_sides_mat = new THREE.MeshLambertMaterial({map:coin_sides_texture}); var coin_sides = new THREE.Mesh( coin_sides_geo, coin_sides_mat ); var coin_cap_mat = new THREE.MeshLambertMaterial({map:coin_cap_texture}); var coin_cap_top = new THREE.Mesh( coin_cap_geo, coin_cap_mat ); var coin_cap_bottom = new THREE.Mesh( coin_cap_geo, coin_cap_mat ); coin_cap_top.position.y = 0.5; coin_cap_bottom.position.y = -0.5; coin_cap_top.rotation.x = Math.PI; var coin = new THREE.Object3D(); coin.add(coin_sides); coin.add(coin_cap_top); coin.add(coin_cap_bottom); </code></pre>
