Syntax
class UGizmoUniformScaleParameterSource : public UGizmoBaseVec2ParameterSource
Remarks
UGizmoUniformScaleParameterSource is an IGizmoVec2ParameterSource implementation that interprets the Vec2 parameter as the position in a 2D plane, and maps this parameter to a change in a uniform scale value. This scale is applied to an IGizmoTransformSource.
The X/Y plane parameter deltas are converted to a uniform scale delta simply by adding them. This assumpes that the 3D plane is oriented such that "positive" along the X and Y tangent axes corresponds to something semantically meaningful. It's up to the client to do this.
This ParameterSource is intended to be used to create 3D Uniform Scale Gizmos.
