User-defined transparency #1562

Open githubkusi opened 1 month ago

githubkusi commented 1 month ago

In order to analyze a mesh, it is often helpful to quickly make the mesh object transparent. f3d already has support for transparency by passing the parameter --opacity=. It would be nice to have a keyboard shortcut for it

Possible solutions

CTRL+T: toggle alpha between 1.0 and e.g 0.3
Shift+scroll wheel: freely choose alpha value between 0 and 1 with your mouse scroll wheel

Sounds like a good idea to me. I think it will probably be addressed in F3D 3.0 with the interactor rework or at least the interactive console. Right @mwestphal ?
