/vis/viewer/

Operations on Geant4 viewers.

Sub-directories :


/vis/viewer/set/

Set view parameters of current viewer.

Commands :


clear [viewer-name]

Clears viewer.
By default, clears current viewer. Specified viewer becomes current. "/vis/viewer/list" to see possible viewer names.

Available at all Geant4 states.

Parameters
viewer-name type s Omittable : current value is used as the default value.


create [scene-handler] [viewer-name] [window-size-hint]

Creates a viewer for the specified scene handler.
Default scene handler is the current scene handler. Invents a name if not supplied. (Note: the system adds information to the name for identification - only the characters up to the first blank are used for removing, selecting, etc.) This scene handler and viewer become current.

Available at all Geant4 states.

Parameters
scene-handler type s Omittable : current value is used as the default value.
viewer-name type s Omittable : current value is used as the default value.
window-size-hint type s Omittable : default value = 600


dolly [increment] [Unit]

Incremental dolly.
Moves the camera incrementally towards target point.

Available at all Geant4 states.

Parameters
increment type d Omittable : current value is used as the default value.
Unit type s Omittable : default value = m Parameter candidates : pc km m cm mm mum nm Ang fm parsec kilometer meter centimeter millimeter micrometer nanometer angstrom fermi


dollyTo [distance] [Unit]

Dolly to specific coordinate.
Places the camera towards target point relative to standard camera point.

Available at all Geant4 states.

Parameters
distance type d Omittable : current value is used as the default value.
Unit type s Omittable : default value = m Parameter candidates : pc km m cm mm mum nm Ang fm parsec kilometer meter centimeter millimeter micrometer nanometer angstrom fermi


flush [viewer-name]

Compound command: "/vis/viewer/refresh" + "/vis/viewer/update".
Useful for refreshing and initiating post-processing for graphics systems which need post-processing. By default, acts on current viewer. "/vis/viewer/list" to see possible viewers. Viewer becomes current.

Available at all Geant4 states.

Parameters
viewer-name type s Omittable : current value is used as the default value.


list [viewer-name] [verbosity]

Lists viewers(s).
See "/vis/verbose" for definition of verbosity.

Available at all Geant4 states.

Parameters
viewer-name type s Omittable : default value = all
verbosity type s Omittable : default value = 0


pan [right-increment] [up-increment] [unit]

Available at all Geant4 states.

Parameters
right-increment type d Omittable : current value is used as the default value.
up-increment type d Omittable : current value is used as the default value.
unit type s Omittable : default value = m


panTo [right] [up] [unit]

Pan to specific coordinate.
Places the camera in this position right and up relative to standard target point (as seen from viewpoint direction).

Available at all Geant4 states.

Parameters
right type d Omittable : current value is used as the default value.
up type d Omittable : current value is used as the default value.
unit type s Omittable : default value = m


rebuild [viewer-name]

Available at all Geant4 states.

Parameters
viewer-name type s Omittable : current value is used as the default value.


refresh [viewer-name]

Refreshes viewer.
By default, acts on current viewer. "/vis/viewer/list" to see possible viewers. Viewer becomes current.

scale [x-scale-multiplier] [y-scale-multiplier] [z-scale-multiplier]

Incremental (non-uniform) scaling.
Multiplies components of current scaling by components of this factor. Scales (x,y,z) by corresponding components of the resulting factor.

Available at all Geant4 states.

Parameters
x-scale-multiplier type d Omittable : current value is used as the default value.
y-scale-multiplier type d Omittable : current value is used as the default value.

Absolute (non-uniform) scaling.
Scales (x,y,z) by corresponding components of this factor.

Available at all Geant4 states.

Parameters
x-scale-factor type d Omittable : current value is used as the default value.
y-scale-factor type d Omittable : current value is used as the default value.
z-scale-factor type d Omittable : current value is used as the default value.

Available at all Geant4 states.

Parameters
viewer-name type s


update [viewer-name]

Triggers graphical database post-processing for viewers using that technique.
For such viewers the view only becomes visible with this command. By default, acts on current viewer. "/vis/viewer/list" to see possible viewers. Viewer becomes current.
