All Implemented Interfaces:

Shape

Enclosing class:

RMMorphShape

public static class RMMorphShape.Morphing2D
extends Object
implements Shape

A morphing shape is a shape which geometry is constructed from two other shapes: a start shape and an end shape.

The morphing property of a morphing shape defines the amount of transformation applied to the start shape to turn it into the end shape.

Both shapes must have the same winding rule.

Constructor Details

Morphing2D

public Morphing2D(Shape startShape,
 Shape endShape)

Creates a new morphing shape. A morphing shape can be used to turn one shape into another one. The transformation can be controlled by the morph property.

Parameters:

startShape - the shape to morph from

endShape - the shape to morph to

Throws:

IllegalPathStateException - if the shapes do not have the same winding rule

See Also:

• getMorphing()
• setMorphing(double)

Method Details

getMorphing

public double getMorphing()

Returns the morphing value between the two shapes.

Returns:

the morphing value between the two shapes

See Also:

• setMorphing(double)

setMorphing

public void setMorphing(double morph)

Sets the morphing value between the two shapes. This value controls the transformation from the start shape to the end shape. A value of 0.0 is the start shap. A value of 1.0 is the end shape. A value of 0.5 is a new shape, morphed half way from the start shape to the end shape.

The specified value should be between 0.0 and 1.0. If not, the value is clamped in the appropriate range.

Parameters:

morph - the morphing value between the two shapes
