AffinePreserve

ostrat.geom.AffinePreserve

A class that can transform itself in 2d geometry and can preserve its type across all affine transformations. This is a key trait, the object can be transformed in 2 dimensional space. Leaf classes must implement the single method fTrans(f: Vec2 => Vec2): T. The related trait TransDistable does the same for fTrans(f: Dist2 => Dist2): T.

Concrete methods

override def scaleXY(xOperand: Double, yOperand: Double): ThisT

Scaling X and Y axes independently, 2D geometric transformation on this GeomElem, returns a new GeomElem. This allows different scaling factors across X and Y dimensions. The return type will be narrowed in sub classes and traits. This is an affine transformation but it is not a similar transformation.

override def scale(operand: Double): ThisT

Uniform 2D geometric scaling transformation. The scale name was chosen for this operation as it is normally the desired operation and preserves Circles and Squares. Use the xyScale method for differential scaling. The Return type will be narrowed in sub traits / classes.

override def slateXY(xDelta: Double, yDelta: Double): ThisT

Translate 2D geometric transformation, taking the xOffset and yOffset as parameters on this GeomElem returning a GeomElem. The Return type will be narrowed in sub traits. End users will often want to use the slate method taking a Pt2 or Vec2 as a parameter, the slateX or the slateY methods. These methods will be offered as extension methods using this method for their implementations.
