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.
