feng3d引擎的WebGPU渲染器,可以让用户无需直接接触WebGPU的API,只需提供渲染所需数据,组织好数据结构便可使用WebGPU渲染,并且支持动态修改数据从而实现动态渲染。
这里完整实现了webgpu的官方示例。
npm install @feng3d/webgpu
import { ISubmit } from "@feng3d/render-api";
import { WebGPU } from "@feng3d/webgpu";
const init = async (canvas: HTMLCanvasElement) =>
{
const devicePixelRatio = window.devicePixelRatio || 1;
canvas.width = canvas.clientWidth * devicePixelRatio;
canvas.height = canvas.clientHeight * devicePixelRatio;
const webgpu = await new WebGPU().init(); // 初始化WebGPU
const submit: ISubmit = { // 一次GPU提交
commandEncoders: [ // 命令编码列表
{
passEncoders: [ // 通道编码列表
{ // 渲染通道
descriptor: { // 渲染通道描述
colorAttachments: [{ // 颜色附件
view: { texture: { context: { canvasId: canvas.id } } }, // 绘制到canvas上
clearValue: [0.0, 0.0, 0.0, 1.0], // 渲染前填充颜色
}],
},
renderObjects: [{ // 渲染对象
pipeline: { // 渲染管线
vertex: { // 顶点着色器
code: `
@vertex
fn main(
@location(0) position: vec2<f32>,
) -> @builtin(position) vec4<f32> {
return vec4<f32>(position, 0.0, 1.0);
}
` },
fragment: { // 片段着色器
code: `
@binding(0) @group(0) var<uniform> color : vec4<f32>;
@fragment
fn main() -> @location(0) vec4f {
return color;
}
` },
},
vertices: {
position: { data: new Float32Array([0.0, 0.5, -0.5, -0.5, 0.5, -0.5]), format: "float32x2" }, // 顶点坐标数据
},
indices: new Uint16Array([0, 1, 2]), // 顶点索引数据
uniforms: { color: [1, 0, 0, 0] }, // Uniform 颜色值。
drawIndexed: { indexCount: 3 }, // 绘制命令
}]
},
]
}
],
};
webgpu.submit(submit); // 提交GPU执行
};
let webgpuCanvas = document.getElementById("webgpu") as HTMLCanvasElement;
if (!webgpuCanvas)
{
webgpuCanvas = document.createElement("canvas");
webgpuCanvas.id = "webgpu";
webgpuCanvas.style.width = "400px";
webgpuCanvas.style.height = "300px";
document.body.appendChild(webgpuCanvas);
}
init(webgpuCanvas);
