https://github.com/vilyLei/voxwebgpu/blob/feature/rendering/src/voxgpu/sample/GameOfLifePretty.ts
系统特性:
1. 用户态与系统态隔离。
2. 高频调用与低频调用隔离。
3. 面向用户的易用性封装。
4. 渲染数据(内外部相关资源)和渲染机制分离。
5. 用户操作和渲染系统调度并行机制。
6. 数据/语义驱动。
7. 异步并行的场景/模型载入。
8. computing与rendering用法机制一致性。 1). 构造过程一致性。 2). 启用过程一致性。 3). 自动兼容到material多pass以及material graph机制中。
当前示例运行效果: WGSL顶点与片段shader:
struct VertexInput {location(0) pos: vec3f,location(1) uv : vec2f,builtin(instance_index) instance: u32
};struct VertexOutput {builtin(position) pos: vec4f,location(0) cell: vec2f,location(1) uv: vec2f,location(2) instance: f32,
};
group(0) binding(0) varuniform grid: vec2f;
group(0) binding(1) varstorage cellState: arrayu32;
group(0) binding(2) varstorage lifeState: arrayf32;
vertex
fn vertMain(input: VertexInput) - VertexOutput {let i f32(input.instance);let cell vec2f(i % grid.x, floor(i / grid.x));let cellOffset cell / grid * 2.0;var state f32(cellState[input.instance]);let gridPos (input.pos.xy * state 1.0) / grid - 1.0 cellOffset;var output: VertexOutput;output.pos vec4f(gridPos, 0.0, 1.0);output.cell cell;output.uv input.uv;output.instance i;return output;
}fragment
fn fragMain(input: VertexOutput) - location(0) vec4f {let c input.cell / grid;var dis length(input.uv - vec2f32(0.5, 0.5));dis min(dis/0.15, 1.0);let i u32(input.instance);var f clamp((lifeState[i])/100.0, 0.0005, 1.0);dis (1.0 - pow(dis, 100.0)) * (1.0 - f) f;var c3 vec3f(c, (1.0 - c.x) * (1.0 - f) f) * dis;return vec4f(c3, 1.0);
