You can further manipulate the view, for example

/vis/viewer/set/viewpointThetaPhi 30 40
/vis/viewer/panTo -5 -1
/vis/viewer/zoom 4.

To draw trajectories:

/vis/scene/add/trajectories

Line: 120 to 127

Check gun settings with:

/gun/info                 
Particle:       e- (m = 0.000510999 GeV)
Kinetic Energy: 100 GeV (momentum = 100.001 GeV)
Position:       0 0 0 cm
Direction:      0.707107 0 0.707107 (theta = 45 deg, phi = 0 deg)
(Steps and smearing are not displayed.)

Random Direction:

Outlined in the Mokka release_notes_mokka-01-02. Note that this has been replaced in newer versions of Mokka such that the new commands are detailed below.

The new method (which works) is outlined in section 'VI. New Commands for the Particle Gun' in the Mokka release_notes_mokka-05-02. Relevant subsections of IV. are "/gun/thetaSmearing", "/gun/phiSmearing" and "/gun/directionSmearingMode".

Works if replace "/gun/direction 1 0 1" with "/gun/directionSmearingMode gaussian" in the e-gun.g4macro

However, it is more useful to have the electron gun 'spray' particles in all regions of the detector, instead of a set direction. This can be obtained for example with:

/gun/direction 0 0 1
/gun/directionSmearingMode uniform
/gun/phiSmearing 360 deg
/gun/thetaSmearing 180 deg

This is documented in section 'VI. New Commands for the Particle Gun' of Mokka release notes 05-02
