Compute Shader是一种特殊的着色器程序，它主要用于执行并行计算任务。与传统的顶点着色器和片段着色器不同，Compute Shader不依赖于图形渲染管线，而是直接在GPU上执行计算任务。这使得Compute Shader在流体仿真、物理模拟等计算密集型任务中具有显著优势。在流体仿真中，粒子系统是一种常用的方法。通过模拟大量粒子的运动...

我们前面提到过无法像 CUDA 那样把 Kernel 和 Host 代码写在一起,因此得提供一个 Kernel 对象,以字符串形式承载 Compute Shader 代码。另外也无法像 CUDA 中核函数传参,需要通过 API 形式传递 Buffer,绑定到指定位置: constrelaxKernel=newKernel({device,computeShader:`// Compute Shader 代码`,});// 绑定 Bu...
Using the WebGPU API, the pipeline consists of one or more programmable stages, each defined by a shader module and an entry function. The compute pipeline has a compute shader stage, and the render pipeline has a vertex shader stage and a fragment shader stage, as shown below is a compute...

Compute ShaderThis is the heart of the raytracer and runs in parallel on the GPU. It bounces rays around the scene and gathers the accumulated color that it finally writes to the pixel in a image buffer. The image buffer is then blitted to the device screen....
