() after loading the usdz via MDLAsset. Inspecting the MDLTexture object I can tell it is assigning a colorspace of linear rgb instead of srgb although the image file in the usdz is srgb. This causes the textures to ultimately render as over saturated. In the code I later convert the ...
rgbColor shade(surface s, ray r, double t) point x = r(t) // evaluate (Phong) illumination equation return color 这样我们实现了一个简易的光线追踪算法(Ray Casting),算法本质上是用我们的光线探针代替了传统的z-buffer + 光栅化模式,传统的光照模型依然适用。 实现了基本的Ray Casting之后,我们要对...

specifically using the newer colorEffect, layerEffect, etc routes. the below does not seem to work. do i have to use the old MTK stuff? import SwiftUI import MetalKit struct HoloPreview: View { let startDate = Date() @State private var noiseTexture: MTLTexture? var body: some View { ...

Color Lookup Uses an color lookup table to remap the colors in an image. Opacity Exposure Saturation Brightness Contrast Color Invert Vibrance Adjusts the saturation of an image while keeping pleasing skin tones. RGB Tone Curve Blend Modes
YUV 颜色编码和RGB颜色编码的红绿蓝三原色组合不同,YUV采用的是明亮度和色度来指定像素的颜色。 Y:明亮度(Luminance、Luma) U、V:色度(Chrominance、Chroma) --> 色度又定义了颜色的:色调和饱和度 为什么用 YUV --> 1、节省带宽 2、比 RGBA 占用 内存空间 更少 ...
