The SEDRIS Data Representation Model
APPENDIX B - Constraints LSR Transformation Components |
---|
An <LSR Transformation> instance L shall have a <Local 4x4>, an ordered set of <LSR Transformation Step> components, or both. If L has both a <Local 4x4> and a set of <LSR Transformation Step> components, the ordered set of <LSR Transformation Step> components shall be mathematically equivalent to the <Local 4x4>.
An <LSR Transformation> has 2 possible representations: as a <Local 4x4>, or as an ordered set of <LSR Transformation Step> components. If the <LSR Transformation> uses both, then the <Local 4x4> and the <LSR Transformation Step> components are alternate representations of the same transformation, so they shall be mathematically equivalent. If the <LSR Transformation> uses neither representation, then no transform is present, which means the <LSR Transformation> should not exist.
