The labour effort is related to maintenance of all software tools and resources shared with the community (see also the others in the following excel shett lines); it includes one full-time researcher (the responsible person for maintenance and management of the MeshLab tool, that is the most complex among our tools and the one with the widest distribution, with more than 350,000 downloads in 2015) and the (part-time) contribution of several other VClab staff (contributing to the other tools).
