All Implemented Interfaces:

Transformable

public class UniformCircleGrid2D
extends Phantom

Simple class to show the Grid2D functionality. We use a Grid2D to create a uniform circle. We use this as a first phantom to investigate parallel beam projection and back-projection.

Constructor Detail

UniformCircleGrid2D

public UniformCircleGrid2D(int x,
                   int y)

The constructor takes two arguments to initialize the grid. The circle will be in the center and have a radius of 45% of the x-dimension. Thus we recommend a grid size that is uniform in both directions.

Parameters:

x -

y -
