TGeoPhysicalNode Class Reference

Physical nodes are the actual 'touchable' objects in the geometry, representing a path of positioned volumes starting with the top node: path=/TOP/A_1/B_4/C_3 , where A, B, C represent names of volumes.

The number of physical nodes is given by the total number of possible of branches in the geometry hierarchy. In case of detector geometries and specially for calorimeters this number can be of the order 1e6-1e9, therefore it is impossible to create all physical nodes as objects in memory. In TGeo, physical nodes are represented by the class TGeoPhysicalNode and can be created on demand for alignment purposes:

TGeoPhysicalNode *pn = new TGeoPhysicalNode("path_to_object")

Once created, a physical node can be misaligned, meaning that its position or even shape can be changed:

pn->Align(TGeoMatrix* newmat, TGeoShape* newshape, Bool_t check=kFALSE)

Bool_t TGeoPhysicalNode::Align ( TGeoMatrix newmat = 0,
TGeoShape newshape = 0,
Bool_t  check = kFALSE,
Double_t  ovlp = 0.001 
)

Align a physical node with a new relative matrix/shape.

Example: /TOP_1/A_1/B_1/C_1 node->Align(transl_1, box) will perform:

  • change RELATIVE translation of C_1 node (with respect to its container volume B) to transl_1
  • change the shape of the C volume NOTE The operations will affect ONLY the LAST node in the branch. All volumes/nodes in the branch represented by this physical node are CLONED so the operation does not affect other possible replicas.
