Project a point from the sphere to the plane.

Specified by:

transform in class Transformer

Parameters:

sphere - a double[3] unit vector

plane - a double[2] preallocated vector.

validPosition

public boolean validPosition(double[] plane)

Description copied from class: Projecter

Is this a valid position in the projection plane for this image. This default is appropriate for all projections where the projection plane is infinite.
