3DMarker
3DMarker is a tool for the tagging of sections in 3D models.
...With 3DMarker you can choose sections of a model and assign them a name and a description. The program includes the Ask Me! mode, a tool with a great pedagogical value: once your sections are named, the users can test their knowledge by identifying the model sections. This function is particularly useful in many different scopes like biology, medicine or engineering.
