Threejs-11、材质文理颜色

主要如下代码

javascript 复制代码

//texture.colorSpace = THREE.SRGBColorSpace;
//texture.colorSpace = THREE.LinearSRGBColorSpace;
texture.colorSpace = THREE.NoColorSpace;
gui.add(texture,'colorSpace',{
  sRGB:THREE.SRGBColorSpace,
  Linear:THREE.LinearSRGBColorSpace,
}).onChange(()=>{
  texture.needsUpdate = true;
})
