Slicing of the 3D Mandelbrot set, and analysis.

Slicing of the 3D Mandelbrot set, and analysis.

Some slices. As followup to: Visualizing the 3D Mandelbrot set, and Some 3D renderings of the Mandelbrot set, here is a bit more experimentation with Paraview slice filtering. This time I saved all the point data with the escape time counts, and rendered it with a few different contours The default slice filter places the plane in the x-y orientation: but we can also tilt it in the Paraview…

Measure time taken to render frame in ParaView

In the ParaView python shell (View > Python Shell), type:

import time

Then, to measure the time taken to render, use:

start=time.clock(); Render(); end=time.clock(); print(end-start);
