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.

Constructors

	Type	Name	Description
		TScale ()	Ctor. initialize to an identity scale, 1.0.
		TScale ( T InScale )	Ctor. initialize from a uniform scale.
		TScale ( const UE::Math::TVector< VType >& InScale )	Ctor. initialize from an UE::Math::TVector defining the 3D scale.

Functions

Type	Name	Description
const TScale	Concatenate ( const TScale& RHS )	Concatenate two scales.
const Vector3Type &	GetVector ()	Access to the underlying UE::Math::TVector that stores the scale.
const TScale	Inverse ()	Invert the scale.
