```typescript
|
||
import { World } from '@antv/g-webgpu';
|
||
|
||
const world = new World({
|
||
engineOptions: {
|
||
supportCompute: true,
|
||
},
|
||
});
|
||
|
||
const compute = world.createComputePipeline({
|
||
shader: `
|
||
//...
|
||
`, // 下一节的 Shader 文本
|
||
dispatch: [1, 1, 1],
|
||
onCompleted: (result) => {
|
||
console.log(result); // [2, 4, 6, 8, 10, 12, 14, 16]
|
||
world.destroy(); // 计算完成后销毁相关 GPU 资源
|
||
},
|
||
});
|
||
|
||
// 绑定输入到 Compute Shader 中的两个参数
|
||
world.setBinding(compute, 'vectorA', [1, 2, 3, 4, 5, 6, 7, 8]);
|
||
world.setBinding(compute, 'vectorB', [1, 2, 3, 4, 5, 6, 7, 8]);
|
||
```
|
||
|
||
使用 TS 编写 Shader：
|
||
|
||
```typescript
|
||
import { globalInvocationID } from 'g-webgpu';
|
||
|
||
@numthreads(8, 1, 1)
|
||
class Add2Vectors {
|
||
@in @out
|
||
vectorA: float[];
|
||
|
||
@in
|
||
vectorB: float[];
|
||
|
||
sum(a: float, b: float): float {
|
||
return a + b;
|
||
}
|
||
|
||
@main
|
||
compute() {
|
||
// 获取当前线程处理的数据
|
||
const a = this.vectorA[globalInvocationID.x];
|
||
const b = this.vectorB[globalInvocationID.x];
|
||
|
||
// 输出当前线程处理完毕的数据，即两个向量相加后的结果
|
||
this.vectorA[globalInvocationID.x] = this.sum(a, b);
|
||
}
|
||
}
|
||
```
