//不需要啊，你用three.js 的 canvas，调用createImage, 然后获取image就行了 image = canvas.createImage(); image.onload = ()=>{ let texture = new THREE.CanvasTexture(image); let spriteMat = new THREE.SpriteMaterial({ map: texture }); let sprite = new THREE.Sprite(spriteMat); this.scene.add(sprite); }; image.onerror = ()=>{ }; image.src = icon.src;
