Overview
- CompositeTransform abstracts a concatenation of transform
- Deriving from TransformBase (non-templated)
- Contain a list of pointers to TransformBase
- Enable the use of mixed dimensionalities ? (e.g. Perspective Transform)
IO
- The TransformFileReader and TransformFileWriter must be modified to manage composite transform.
Writing
- The TransformFileWriter can dynamic_cast to CompositeTransform
- Then extract its internal transforms
Reading
- The TransformFileReader will create the CompositeTransform directly by using the standard Factories.
- Conditional code will deal with reading the N Transform components.
Changes
- Refactor GetJacobians() to manage sparse matrices OR
- Make them obsolete and add to the Transforms the method that provide the service of mapping a point through the Jacobian on the transform. In this way they don't have to be represented explicitly.
