这里可以使用canvas作为纹理贴图，Three为我们提供里CanvasTexture
function getTextCanvas(text){ ?var width=512, height=256; ?var canvas = document.createElement(‘canvas‘); canvas.width = width; canvas.height = height; var ctx = canvas.getContext(‘2d‘); ctx.fillStyle = ‘#C3C3C3‘; ctx.fillRect(0, 0, width, height); ctx.font = 50+‘px " bold‘; ctx.fillStyle = ‘#2891FF‘; ctx.textAlign = ‘center‘; ctx.textBaseline = ‘middle‘; ctx.fillText(text, width/2,height/2); ?return canvas; }var materials = [ ?new THREE.MeshBasicMaterial( { color: ‘blue‘ } ), // right new THREE.MeshBasicMaterial( { color: ‘yellow‘ } ), // left new THREE.MeshBasicMaterial( { map: new THREE.CanvasTexture(getTextCanvas(‘Leo Test Label‘)) } ), // top new THREE.MeshBasicMaterial( { color: ‘black‘ } ), // bottom new THREE.MeshBasicMaterial( { color: ‘green‘ } ), // back new THREE.MeshBasicMaterial( { color: ‘red‘ } ) // front ?];这样我们就可以利用canvas画上文字或者图形，用来填充纹理贴图。
