Convert Simple Voxel SVX files to OpenVDB files.

One nice benefit of converting files in this way is that it allows voxel clouds to be viewed using the vdb_view utility or Houdini tools. Currently there aren't any tools to view SVX files directly, as far as I'm aware.

The source code is available from GitHub. It can be built easily using autotools.


svx2vdb is a simple command-line tool that takes two parameters.

svx2vdb infile.svx outfile.vdb

The first parameter infile.svx should be an existing SVX format file to read in. This will be converted to the OpenVDB format file written to outfile.vdb.

If you have the OpenVDB tools installed, you can then view the resulting output file as follows.

vdb_view outfile.vdb

An example SVX file is provided in the source repository. Shapeways also provide a sphere example, or you can generate your own files using Functy.


svx2vdb is released under the MIT License.


The following is a shape rendered using Functy on the left, exported as SVX then converted to OpenVDB and shown using vdb_view on the right.

Two example shapes converted from SVX to OpenVDB. The left is the Shapeways sphere example, the right is a fractal Quaternion Julia set created by shawn_halayka.

The svx2vdb tool has now been added to the Linux software page. It's still very early code, but seems to work on the files I've tried so far.
