+# openastroviz-webgpu-compute
+
+WebGPU compute scaffolding for OpenAstroViz. This crate introduces a browser-native
+`GpuBackend` implementation with a WGSL kernel entrypoint intended for the FP32
+SGP4 port from CUDA.
+
+## Build to WebAssembly with wasm-pack
+
+```bash
+wasm-pack build webgpu-compute --target web --release --out-dir pkg
+```
+
+The generated `pkg/` directory can be consumed directly by the React/Vite frontend,
+which can call `initWebGpuBackend()` and then dispatch compute work using
+`dispatchSgp4Fp32Step(batchSize)`.
