The SEDRIS Data Representation Model
APPENDIX B - Constraints LSR Transformation Components |
|---|
An <LSR Transformation> instance L shall have a <Local 4x4> component, an ordered set of <LSR Transformation Step> components, or both. If L has both a <Local 4x4> component and a set of <LSR Transformation Step> components, the ordered set of <LSR Transformation Step> components shall be mathematically equivalent to the <Local 4x4> component.
An <LSR Transformation> instance has two possible representations: as a <Local 4x4> component, or as an ordered set of <LSR Transformation Step> components. If the <LSR Transformation> instance uses both, the <Local 4x4> component and the <LSR Transformation Step> components are alternate representations of the same transformation, so they shall be mathematically equivalent. If the <LSR Transformation> instance uses neither representation, no transform is present, which means that the <LSR Transformation> instance should not exist.
