Changing "tilt" of visualization

[icmeyer]

Hi,

I have a geometry I am visualizing using OpenGL. I am able to get the desired viewpoint using

/vis/viewer/set/viewpointVector  1 -1 1

I am not very familiar with computer graphics, but is there a way to “tilt” or “rotate” the camera at that point? I can accomplish this in ParaView by holding shift when I move the mouse.

Right now the visualization looks like this

But I would like to tilt the view to look like

I can always post process the image, but just curious if there were any native Geant4 commands.

Thanks for any help!

_Geant4 Version: 10.07
_Operating System: macOS Ventura 13.4
_Compiler/Version: Apple clang version 14.0.3
_CMake Version: 3.26.4

Hi Isaac

A view is defined by a viewpoint and an up-vector. You can change the up-vector with

/vis/viewer/set/upVector

Alternatively, you can

/vis/viewer/set/rotationStyle freeRotation

That was exactly what I was looking for, thank you!
