public class CircleCursor3D<T> extends Object implements net.imglib2.Cursor<T>
Iterate the pixels of an oriented circle in 3-space using Bresenham's algorithm, where the circle is constructed from the unit normal to the circle plane, the center point, and radius. Alternatively, x and y basis vectors may be used in place of the circle normal.

    • CircleCursor3D

      public CircleCursor3D(net.imglib2.RandomAccessible<T> rai, net.imglib2.Localizable center, long radius, double[] circleNorm)
      Iterates over a Bresenham circle in the target RandomAccessible. Each point of the circle is iterated exactly once, and there is no "hole" in the circle.
      Parameters:
      rai - the random accessible. It is the caller's responsibility to ensure it can be accessed everywhere the circle will be iterated.
      center - the circle center. Must be at least of dimension 3. Dimensions 0, 1 and 2 are used to specify the circle center.
      radius - the circle radius.
      circleNorm - the unit normal to the circle plane, must be 3-dimensional. The "new" x and y basis vectors will be constructed from this vector.

      public CircleCursor3D(net.imglib2.RandomAccessible<T> rai, net.imglib2.Localizable center, long radius, double[] xBasis, double[] yBasis)
      Iterates over a Bresenham circle in the target RandomAccessible. Each point of the circle is iterated exactly once, and there is no "hole" in the circle.
      Parameters:
      rai - the random accessible. It is the caller responsibility to ensure it can be accessed everywhere the circle will be iterated.
      center - the circle center.
      radius - the circle radius.
      xBasis - the vector representing the "new" x-axis of the circle plane. Should be orthogonal to both the circle normal and the yBasis
      yBasis - the vector representing the "new" y-axis of the circle plane. Should be orthogonal to both the circle normal and the xBasis
