displayHeadTime [displayHeadTime] [screenX] [screenY] [screenSize] [red] [green] [blue]

Display head time of range in 2D text.
For these commands use /vis/scene/add/trajectories rich /vis/modeling/trajectories/drawByCharge-0/default/setTimeSliceInterval 0.01 ns then typically /vis/viewer/set/timeWindow/displayLightFront true 0 0 -50 cm -0.5 ns /vis/viewer/set/timeWindow/displayHeadTime true /vis/viewer/set/timeWindow/fadeFactor 1 /run/beamOn # or several until you get a good event or events /vis/viewer/set/timeWindow/startTime 0 ns 1 ns /vis/viewer/save /vis/viewer/set/timeWindow/startTime 1 ns 1 ns then zoom, pan etc to a view of interest and /vis/viewer/save then repeat with next start time, another view and a save, then try /vis/viewer/interpolate

Available at all Geant4 states.

Parameters

displayHeadTime	type b
screenX	type d	Omittable : default value = -0.9	Parameter range : screenX >= -1. && screenX <= 1.
screenY	type d	Omittable : default value = -0.9	Parameter range : screenY >= -1. && screenY <= 1.
screenSize	type d	Omittable : default value = 24
red	type d	Omittable : default value = 0	Parameter range : red >= 0. && red <= 1.
green	type d	Omittable : default value = 1	Parameter range : green >= 0. && green <= 1.
blue	type d	Omittable : default value = 1	Parameter range : blue >= 0. && blue <= 1.

displayLightFront [displayLightFront] [originX] [originY] [originZ] [space_unit] [originT] [time_unit] [red] [green] [blue]

Display the light front at head time.
Tip: The trajectories can appear of jump ahead of the light front because their time range overlaps the viewer's time range. To average out this discrete time effect, advance the light front by half the trajectories interval. E.g., if the trajectory time slice interval is 0.01 ns: /vis/viewer/set/timeWindow/displayLightFront true -90 0 0 mm -0.005 ns To prevent them beating the light front at all: /vis/viewer/set/timeWindow/displayLightFront true -90 0 0 mm -0.01 ns
For these commands use /vis/scene/add/trajectories rich /vis/modeling/trajectories/drawByCharge-0/default/setTimeSliceInterval 0.01 ns then typically /vis/viewer/set/timeWindow/displayLightFront true 0 0 -50 cm -0.5 ns /vis/viewer/set/timeWindow/displayHeadTime true /vis/viewer/set/timeWindow/fadeFactor 1 /run/beamOn # or several until you get a good event or events /vis/viewer/set/timeWindow/startTime 0 ns 1 ns /vis/viewer/save /vis/viewer/set/timeWindow/startTime 1 ns 1 ns then zoom, pan etc to a view of interest and /vis/viewer/save then repeat with next start time, another view and a save, then try /vis/viewer/interpolate

space_unit	type s	Omittable : default value = m
