In SketchUp and SolidWorks, I use a 3D mouse routinely ( http://www.3dconnexion.com/products/spacenavigator-for-notebooks.html ). You might be surprised at how hard it is to manipulate a 3D model with an standard mouse after becoming used to having such a controller.
my personal opinion is that there are two separate UIs.
- the main one is the 2D, and it requires a precision 2D movement ==> the regular mouse is adequate
- the additional one is the 3D cube view, that you can rotate in any direction ==> a 3D controller can help indeed.
I don’t see a reason why you wouldn’t be able to use these specialised mice with EyeWire. Let me know if you encounter any problems. Very few people are going to purchase a special mouse for EW, but I’m not against providing some basic support if you encounter problems. We’d need to get one for the lab first of course, but I’m kind of getting into 3d printing myself, so maybe I’d get one for kicks.
