T3x3Transformation = class(TTransformation)

Description ​

T3x3Transformation is the base class for linear transformations that use a 3×3 matrix (TFloatMatrix) to map coordinates.

Internally it maintains both floating-point (Matrix, FInverseMatrix) and 16.16 fixed-point (FFixedMatrix, FInverseFixedMatrix) matrix structures for accelerated fixed-point sampling.
