Blender Volumetics 2.48.4 (for Windows)

With the help of the template you do not need to know much about Blender. But in case you would like to understand and use Blender for your own purposes, you can find the official manual for Blender here and a nice introduction video can be found here.
Extract the voxeldata directory into the toolbox-directory of your SPM installation. After a restart of SPM you should find the toolbox under TASK - Tools - Voxeldata.
14 templates for all kinds of visualizations. Sample data will follow.
