TransformBy(Matrix3, Vector3)

Moves, scales, and/or rotates the current entity given a 3x3 transformation matrix and a translation vector.

Declaration
public override void TransformBy(Matrix3 transformation, Vector3 translation)
Parameters
Type Name Description
Matrix3 transformation

Transformation matrix.
Vector3 translation

Translation vector.
Overrides
Remarks

Non-uniform scaling is not supported, create an ellipse from the circle data and transform that instead.
Matrix3 adopts the convention of using column vectors to represent a transformation matrix.
