setAssignToPrimaries()

void setAssignToPrimaries ( bool on )

inline

If true, hits created by secondary particles (e.g.

delta electrons) will be assigned to the original primary particle.

Definition at line 268 of file EVEVisualization.h.

{ m_assignToPrimaries = on; }

setErrScale()

void setErrScale

(

double

errScale = 1.

)

Set the scaling factor for the visualization of track hit errors.

(only affects PXD and SpacePoint hits, which are somewhat small

Definition at line 184 of file EVEVisualization.cc.

{ m_errorScale = errScale; }

setHideSecondaries()

void setHideSecondaries ( bool on )

inline

If true, secondary MCParticles (and hits created by them) will not be shown.

Definition at line 271 of file EVEVisualization.h.

{ m_hideSecondaries = on; }

setOptions()

void setOptions

(

const std::string &

opts

)

Set the display options.

The option string lets you steer the way the events are displayed. The following options are available:

'D': Draw detectors. This causes a simple representation for all detectors to be drawn. For planar detectors, this is a plane with the same position and orientation of the real detector plane, but with different size. For wires, this is a tube whose diameter is equal to the value measured by the wire. Spacepoint hits are not affected by this option.

'H': Draw hits. This causes the hits to be visualized. Normally, the size of the hit representation is connected to the covariance matrix of the hit, scaled by the value set in setErrScale which is normally 1. Normally used in connection with 'D'.

'M': Draw track markers. Draw the intersection points between the track and the virtual (and/or real) detector planes. 'P': Draw detector planes. Draws the virtual (and/or real) detector planes.
