Coordinate Systems and Locations
Introduction
During a test, it might be relevant what the exact locations of a transducer is. A location can be expressed relative to a coordinate system.
Coordinate Systems
A coordinate systems is a orthogonal, threedimensional system. It can be defined relative to a parent coordinate system with a rotation axis, a rotation angle and a translation.
Testdefiner
Coordinate systems are defined in a Testdefinition under Advanced -> Coordinate Systems. Systems can be loaded from a file or entered manually.
Notes:
- A coordinate system can have one parent coordinate system.
- The rotation axis doesn't have to be normalized.
- To transform from the parent system to the child system, first the translation is applied, then the rotation.
