Syntax
template<typename T>
class TScale
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/double -> represents a uniform scale.
- TScale
-> represents a 3D non-uniform scale. - UE::Math::TVector
-> represents a 3D translation. - UE::Math::TRotator
-> represents a pure rotation. - UE::Math::TQuat
-> represents a pure rotation. - UE::Math::TMatrix
-> represents a general 3D homogeneous transform. Represents a 3D non-uniform scale (to disambiguate from an UE::Math::TVector , which is used for translation).
Serves as a good base example of how to write a class that supports the basic transform calculus operations.
