ROOT 6.18/05 Reference Guide |
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:
Once created, a physical node can be misaligned, meaning that its position or even shape can be changed:
