https://threejs.org/examples/#webgl_loader_gltf_iridescence
目前我们已有的: basetexture 对应 薄膜干涉颜色纹理,iridescence 对应 强度,iridescent ior 对应 折射率,厚度仅输出了 iridescence Thickness 需要增加的: 针对gltf2.0的标准补充 薄膜干涉厚度纹理,薄膜干涉最小厚度,薄膜干涉最大厚度

贴一下 glTF 标准的地址:https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_materials_iridescence
Sorry, something went wrong.
pow 和 square 这个不算差异,只是语法不同
调研一下这个默认参数,折射率1.3,厚度400,有什么讲究没,我看我们目前是2和0.1,相差有点大
