# VDB Desktop/Server Toolchain

This directory is the native OpenVDB boundary for the Web application. It is not linked into the browser WASM build.

```bash
tools/vdb/provision-resources.sh
npm --prefix web run test:vdb-native
```

The provisioner builds two native executables, generates real bounded OpenVDB fixtures once without overwriting
their UUID-bearing source files, downloads the official
CC-BY-4.0 `sphere.vdb` sample with its Git LFS SHA-256, converts the fixtures with OpenVDB 13.0/NanoVDB 32.9,
and writes the resources under `/home/mes123456/resource-library/blender-web-vdb`.

`vdb_to_nanovdb` accepts only `.vdb`, limits source/output bytes, grid count and active voxels, supports a grid
allowlist, writes uncompressed standard NanoVDB segments, and emits a machine-readable conversion report.
The current browser renderer remains blocked; these tools establish the conversion and resource boundary only.
