## ParaView Mandelbrot Source

The Mandelbrot source uses the VTK source vtkImageMandelbrotSource. The source generates and displays a Mandelbrot fractal. If a two dimensional extent is used, then the image is displayed. If a three dimensional extent is used, the bounding box is displayed. The output of the Mandelbrot source is image data.

- The user selects
**Source->Mandelbrot**from the main menu. - The
**Whole Extent**boxes allow the user to specify the minimum and maximum resolution of the Mandelbrot plane to be created. By default it ranges from 0 to 250 in the X and Y direction, and from 0 to 0 in the Z direction. This is fairly coarse. Increasing it to 0 to 2,500 gives better resolution, but takes longer to render. - The
**Projection Axes**boxes allow the user to choose which axis of the data to be displayed. - The
**Origin CX**boxes allow the user to specify the real and imaginary values for the constant C and initial value X. The initial values are -1.75, -1.25, 0, and 0. By lowering the initial real value of C from -1.75 to -2.0, it shifts the grid to the left. By raising the initial real value of C from -1.75 to -1.5, it shifts the grid to the right. - The
**Size CX**boxes allow the user to specify the length of the Mandelbrot plane to be created. The initial values are 2.5, 2.5, 2, and 1.5. By raising the initial length of C from 2.5 to 3.0, it lengthens the grid to the right. - The
**Max. iterations**box allow the user to specify the maximum number of iterations to be performed. - The
**Subsample**box allows the user to specify the subsample iterations to be performed. - The
**Apply**button must be pressed before the Mandelbrot plane will be generated.
