Class Tot

java.lang.Object
All Implemented Interfaces:
java.io.Serializable, Component

public class Tot
extends Projecter
This class provides for the translation between coordinates and the Tiled Octahedral Tangent projection.

The projection is centered at the north pole. The south pole is projected to the four corners at (+/-1, +/-1). The equator projects to the diagonals running between the points (-1,0)->(0,1), (0,1)->(1,0), (1,0)->(0,-1), (-1,0)->(0,-1). These diagonals divide the four unit squares at the center of the coordinate grid into 8 right isoceles triangles.

    • transform

      public void transform​(double[] unit, double[] plane)
      Description copied from class: Transformer
      Convert a single point where the output vector is supplied.
      Specified by:
      transform in class Transformer
      Parameters:
      unit - The input vector.
      plane - The output vector, it may be the same as the input vector if the dimensionalities are the same. All transformers are expected to work with aliased inputs and output.
