# WBV2-P1120-000: Volume NanoVDB module
|
|
|
|
- task: `WBV2-P1120-000`
|
|
- parent: `WBV2-P1119-000`
|
|
- status: `in_progress`
|
|
- gap: `workflow:module_volume_nanovdb`
|
|
- ownerFamily: `MEDIA`
|
|
- targetImplementationClass: `LOCAL_BOUNDED`
|
|
|
|
## 目标
|
|
|
|
按功能模块验证 NanoVDB manifest/chunk identity、paged feedback、OPFS commit/restart、WebGPU availability 和 main/offscreen viewport roundtrip。
|
|
|
|
## 输入与范围
|
|
|
|
- Protocol: `web/protocol/volume-vdb.ts`, `web/protocol/nanovdb-page-feedback.ts`, `web/protocol/nanovdb-device-recovery.ts`, `web/protocol/storage.ts`
|
|
- Volume implementation: `web/app/src/volume/nanovdb-opfs.ts`, `web/app/src/volume/nanovdb-stream.ts`, `web/app/src/volume/nanovdb-viewport.ts`, `web/app/src/volume/nanovdb-float32.ts`, `web/app/src/render/nanovdb-volume-renderer.ts`
|
|
- Workers/UI: `web/app/src/workers/vdb-opfs-test.worker.ts`, `web/app/src/workers/storage.worker.ts`, `web/app/src/app/App.tsx`
|
|
|
|
## 验收
|
|
|
|
```bash
|
|
npm --prefix web run test:vdb-availability
|
|
npm --prefix web run test:vdb-native
|
|
npm --prefix web run test:nanovdb-page-feedback
|
|
npm --prefix web run test:nanovdb-opfs-restart
|
|
npm --prefix web run test:nanovdb-volume-roundtrip
|
|
npm --prefix web run typecheck
|
|
```
|
|
|
|
必须记录 manifest/chunk 正例、hash/stale/WebGPU block 负例、OPFS restart、feedback resume、quota/device cleanup、main/offscreen viewport 和 Chromium save/reopen。OpenVDB browser decoder 关闭、advanced material blocked 等能力保持显式。

## 交付与回滚
|
|
|
|
- Receipt: `tests/golden/WBV2-P1120-000/module-receipt.json`
|
|
- Manifest: `tests/golden/WBV2-P1120-000/manifest.json`
|
|
- Status: `docs/status/WBV2-P1120-000.md`
