Unless your users are great fans of downloading 100s of MB of data, OpenVDB file format is not very practical in the browser. While WebGL and Three.js are technically capable of rendering your high-tech Houdini flamethrower simulation - there is no easy or practical way of doing so, without downloading giant files and writing custom shaders.

Volume Designer aims to help you with the following:

Loading and modifying OpenVDB (.vdb) files directly in Three.js.

Creating a procedural workflow for volumetric shapes.

Applying masks and movement to the volumes in Three.js.

Creating custom volumetric clouds and what-not in the browser, without using external software.

Baking volumes at various resolutions, reducing the file sizes dramatically compared to using .vdb directly.
