I want to visualize the trajectroy of particles, but Some Values for visualization were not work weell like below:
/vis/modeling/trajectories/drawByCharge-0/default/setStepPtsSize 20000 (no differnce with 2)
/vis/modeling/trajectories/drawByCharge-0/default/setTimeSliceInterval 10 s
how to active these command?
What graphics driver are you using? Not all drivers are capable of changing line width, for example.
Qt is the user interface system. Using Qt, there are several drivers - OGL (OpenGL), Qt3D. TOOLSSG_QT_GLES. Which of these?
With OGL, you should be able to change the line width and see text. With Qt3D, you cannot change the line width, nor draw text (it is still under development).
I see from your movie2.mac, you are using OGL. But strangely, your images do not have text. So how are you producing your images? If you use
/vis/ogl/export, I think it true that you loose text. Maybe a screen grab would be simpler?
Finally, what version of Geant4 are you using? And what operating system?
The version of Geant4 is 10.7_patch-01, the operating system is ubuntu 20.04.
