rTDTP — 3d2png — is a conversion tool used to turn STL files (a three-dimensional model filetype) into PNG thumbnails for display on MediaWiki sites. This will need to be packaged so it can be deployed via puppet to the appropriate servers.
Work on this is ongoing, but there are some road bumps, specifically relating to the node-canvas library which is installed via npm, and requires a g++ build, which may affect the architectures supported by any package we produce.
