Method Summary

java.lang.String	getDescription() Should provide a general description of the transformation.
processing.core.PVector	invTransformCoords(processing.core.PVector p) Should perform an inverse transform on the given coordinates.
processing.core.PVector	transformCoords(processing.core.PVector p) Should perform a forward transform on the given coordinates.

Method Detail

getDescription

java.lang.String getDescription()

Should provide a general description of the transformation.

Returns:

Description of the transformation.

transformCoords

processing.core.PVector transformCoords(processing.core.PVector p)

Should perform a forward transform on the given coordinates. Applying transformCoords() followed by invTransformCoords() to a point should leave it unaltered (other than possibly subject to minor rounding effects).

Parameters:

p - point location coordinates to transform.

Returns:

Transformed point coordinates.

invTransformCoords

processing.core.PVector invTransformCoords(processing.core.PVector p)

Should perform an inverse transform on the given coordinates. Applying transformCoords() followed by invTransformCoords() to a point should leave it unaltered (other than possibly subject to minor rounding effects).

Parameters:

p - point location coordinates to transform.

Returns:

Transformed point coordinates.
