Remarks

Transform calculus for 3D types. Since UE4 already has existing 3D transform types, this is mostly a set of adapter overloads for the primitive operations requires by the transform calculus framework.

The following types are adapted.

  • float -> represents a uniform scale.

  • FScale -> represents a 3D non-uniform scale.

  • FVector -> represents a 3D translation.

  • FRotator -> represents a pure rotation.

  • FQuat -> represents a pure rotation.

  • FMatrix -> represents a general 3D homogeneous transform. Represents a 3D non-uniform scale (to disambiguate from an FVector, which is used for translation).

Serves as a good base example of how to write a class that supports the basic transform calculus operations.
