TRestDetectorHitsRotationProcess Class Reference

Detailed Description

A process to rotate hits from a given center and axis.

TRestDetectorHitsRotationProcess will add a rotation of the x,y,z hits in the space. The rotation will be done respect to a center and an axis provided by the user.

<addProcess type="TRestDetectorHitsRotationProcess" name="rotZ45"
title="A 45 degrees rotation">
<parameter name="axis" value="(0,0,1)" />
<parameter name="center" value="(0,0,0)" />
<parameter name="angle" value="45degrees" />
</addProcess>
Warning
This process will only be valid for those detector hits of type XYZ, where the (x,y,z) coordinates take simultaneously physical values. When the hits contain a non-valid (undetermined) coordinate component this transformation will have non-sense and this process will do nothing.

The following figure has been produced using the rotation.C defined under detector/pipeline/hits/rotation/. On the left we have the original hits event distribution. On the middle the hits with a 90 degrees clock-wise rotation with center at (0,0,0). On the right the original hits after a clock-wise rotation of 45 degrees with center at (-25,25,0). The axis for both rotations is along the Z-axis.

Constructor & Destructor Documentation

◆ TRestDetectorHitsRotationProcess()

TRestDetectorHitsRotationProcess::TRestDetectorHitsRotationProcess ( const char *  configFilename)

Constructor loading data from a config file.

If no configuration path is defined using TRestMetadata::SetConfigFilePath the path to the config file must be specified using full path, absolute or relative.

The default behaviour is that the config file must be specified with full path, absolute or relative.

Parameters
configFilenameA const char* giving the path to an RML file.
