Project Description
The ITK transforms ScaleSkewVersor3D, and Simularity3D surprisinging use addition to compose the matrix components instead of matrix multiplication.
Objective
- Determine if this is expected and known behavior, and determine if the expected transforms are needed.
Approach, Plan
Progress
- Discussed the issue
- Determined that documentation is needed to clearly describe what is being done to preserve backwards compatibility. Changing the current implementation is too intrusive. New composite transform based transforms should be created to provide a more correct solution.
