Commands :

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

Display head time of range in 2D text.

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/ogl/set/displayLightFront true -90 0 0 mm -0.005 ns To prevent them beating the light front at all: /vis/ogl/set/displayLightFront true -90 0 0 mm -0.01 ns

Available at all Geant4 states.

Parameters

displayLightFront	type b
originX	type d	Omittable : default value = 0
originY	type d	Omittable : default value = 0
originZ	type d	Omittable : default value = 0
space_unit	type s	Omittable : default value = m
originT	type d	Omittable : default value = 0
time_unit	type s	Omittable : default value = s
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 = 0	Parameter range : blue >= 0. && blue <= 1.

displayListLimit [limit]

Set/reset display list limit (to avoid memory exhaustion).

Range : limit>=10000

Available at all Geant4 states.

Parameters

limit

type i

Omittable : default value = 50000

endTime [end-time] [end-time-unit] [time-range] [time-range-unit]

Set end and range of track time.

Available at all Geant4 states.

Parameters

end-time	type d
end-time-unit	type s
time-range	type d	Omittable : default value = -1
time-range-unit	type s	Omittable : default value = ns

eventsDrawInterval [interval]

Set number of events allowed in drawing pipeline - speeds drawing
By default, the screen is updated at the end of every event. Allowing OpenGL to buffer several events can make a big improvement in drawing speed.

Available at all Geant4 states.

Parameters

interval

type i

Omittable : default value = 1

fade [fadefactor]

0: no fade; 1: maximum fade with time within range.

Range : fadefactor>=0.&&fadefactor<=1.

Available at all Geant4 states.

Parameters

fadefactor

type d

printFilename [name] [incremental]

Set print filename
Setting 'incremental' will increment filename by one at each new print, starting at 0

Available at all Geant4 states.

Parameters

name	type s	Omittable : default value = G4OpenGL
incremental	type b	Omittable : default value = 1

exportFormat [format]

Set export format
By default, pdf/eps/svg/ps are available. Depending of viewers several other format are available.
Try /vis/ogl/set/exportFormat without parameters to see them.
Changing format will reset the incremental suffix to 0.

Available at all Geant4 states.

Parameters

format

type s

Omittable : default value =

printMode [print_mode]

Set print mode, only available for "ps" format

Available at all Geant4 states.

Parameters

print_mode

type s

Omittable : default value = vectored

Parameter candidates : vectored pixmap

printSize [width] [height]

Set print size
Tip : -1 will mean 'print size' = 'window size'
Setting size greatter than your maximum graphic card capacity , will set the size to maximum size.

Available at all Geant4 states.

Parameters

width	type d
height	type d

startTime [start-time] [start-time-unit] [time-range] [time-range-unit]

Set start and range of track time.

Available at all Geant4 states.

Parameters

start-time	type d
start-time-unit	type s
time-range	type d	Omittable : default value = -1
time-range-unit	type s	Omittable : default value = ns

transparency [transparency-enabled]

True/false to enable/disable rendering of transparent objects.

Available at all Geant4 states.

Parameters

transparency-enabled

type b

Omittable : default value = 1
