zoom/unzoom in 3d view using keyboard keys #43

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What should be the improvement?

Could you detail it by giving examples (code, files)?

I personally think that a shortcut for zooming/unzooming when displaying my 
files in the 3d view would be very useful. The main utility, in my opinion, 
would be not to speed up the visual inspection, but to allow people using a 
laptop without a mouse to be able to zoom closer to the markers (otherwise they 
open a c3d file and they have to operate with very tiny markers). Those 
shortcuts in OpenSim are "i" and "o" for instance. 

Thanks for providing such a good tool to the community,

Luca

Thanks for this suggestions Luca.

Before to add it in the TODO list, I would like to suggest you three ways which 
may solve your problem (tiny markers).
 1. You can go in the option (menu Edit > Options), select the tab Visualization and modifiy the default radius to the desired value. If you don't have a model visual configuration (MVC file) loaded, then markers for your next file will be bigger.
 2. Mokka 0.6 is now able to save the position of the camera when you save a layout. So, you can set the camera position closer of your markers data set. To do that, zoom where you want, click on the action "Window > Save Current Layout". This layout will be then the default layout used. If you close/reload Mokka, the camera will be at location saved previously. You will see your markers closer.
3. If could not be easy on a laptop, but the combination Ctrl + LMB (left mouse 
button) + scroll up/down (on your trakpad) zoom/unzoom 3D views.

Tell me if these methods can solve your problem.

Hi Arnaud,
thanks for the several options. 
A possible situation I was referring to for my feature request is loading a c3d 
file in Mokka and wanting to see a detail e.g. the foot markers at the heel 
strike time in the area of contact with the force plate. The option closer to a 
solution to my issue would be the 3rd one you suggested, which is indeed a bit 
unpractical on a laptop but still a solution!
Thank you!

Luca
