Blender addon to import images as meshes. Inspired by: ImagesAsPlanes

The algorithm simply creates a voxel for each image pixel depending on a threshold. For best results you should use black and white images. At the moment, only square images are supported.

It's like just about every other Blender addon. Download the file here.

From the Blender file menu, choose 'User Preferences'. Switch to the 'Add-ons' tab, then select 'Install Add-on from file'. Browse to the location of the downloaded addon zip file. Enable 'Import Images as Meshes' from the list of add-ons.

There should be a 'ImagesAsMeshes' importer on the import "File>Import" Toolbar.
