Mandelbrot Set made simple (Python)

2015-12-28T17:56:08-08:00

Python recipe 579143 by Jack Trainor (educational, fractal, graphics, mandelbrot, mathematics). Revision 2.

This is a mini-framework for exploring the Mandelbrot Set.

It outputs to a Tkinter window or to a PNG file (Pillow package required). It includes a disk caching mechanism for saving and later retrieving Mandelbrot calculations to avoid recalculating the Set on each run.

See module documentation for further information. Compatible with Python 2 and 3.

Simple Text Mode Digital Oscilloscope Graphics DEMO. (Python)

2014-01-21T19:07:49-08:00

Python recipe 578812 by Barry Walker (apple, demo, graphics, linux, macbook_pro).

This is a DEMO to switch a *NIX terminal from text to _graphics_ mode on the fly.

The graphics characters are limited to lowercase 'a' through 'z' and this DEMO just prints a small subset to see what a fun, kids level, 8 channel Logic-Analyser/Digital-Oscilloscope might look like.

This may not work in every *NIX style terminal but does work on default terminals using bash on OSX 10.7.5, PCLinuxOS 2009 and Debian Linux 6.0.x.

Tested on Python 2.5.x to 3.3.2 on the above platforms... (It might work on earlier versions of Python but untested.)

Enjoy finding simple solutions to often very difficult problems...

Voxel Based Ray Tracing (Python)

2013-08-29T06:11:41-07:00

Python recipe 578652 by FB36 (graphics, image, math, mathematics).

The standard ray tracing algorithm seems unnatural to me because everytime a ray reflects/refracts all (primitive) objects in the scene must be tested for intersection; no matter where they located!

In this method there is no such thing. It just moves each ray voxel by voxel until it hits an opaque/reflective(/refractive) voxel.

I made many simplifications so the image is crude.

pack multiple images of different sizes into one image (Python)

2013-06-27T14:50:37-07:00

Python recipe 578585 by Hugo (graphics).

Packing images of different sizes into one image is often required in order to efficiently use hardware accelerated texture mapping functions of 3D video cards.

Dynamical Billiards Simulation (Python)

2013-06-20T06:57:57-07:00

Python recipe 578572 by Steve Wadley (chaos, graphics, math, pil, random).

It simulates reflections of a ball on a billiards table that has one or more circular obstacles. (This can also be thought as a 2d ray-tracing.)

Most of the time the path of the ball would be chaotic (meaning, if another ball started from any slightly different location or direction then its path would be very different after a short while).

See Wikipedia for more info: http://en.wikipedia.org/wiki/Dynamical_billiards

Worley Noise Generator (Python)

2013-02-16T21:11:05-08:00

Python recipe 578459 by FB36 (fractal, graphics, math, mathematics).

Worley Noise is a type of parametric texture used for water, rock, leaf etc. textures in computer graphics.

The algorithm is a slightly modified version of Voronoi Diagram.

Perlin Noise Generator (Python)

2013-02-23T05:23:24-08:00

Python recipe 578470 by FB36 (fractal, graphics, image, images, math, mathematics, pil). Revision 2.

Perlin Noise Generator using Bilinear Interpolation.

Bilinear Interpolation (Python)

2013-02-23T04:00:52-08:00

Python recipe 578469 by FB36 (graphics, image, math, mathematics, pil).

Creates a surface from a grid of random numbers using Bilinear Interpolation.

Random Maze Generator (Python)

2012-12-14T09:09:22-08:00

Python recipe 578356 by FB36 (ai, game, graphics, pil). Revision 2.

Random maze generator using depth-first search.

It starts the maze path from a random cell and there is no exit defined but actually any 2 cells on the path (white cells) can be assigned to be entry and exit locations. (I could just add code to randomly select 2 white cells and change their colors to something else but I thought it looks better this way.)

Random Multi-Maze Generator (Python)

2012-12-14T11:23:29-08:00

Python recipe 578378 by FB36 (ai, game, graphics, pil).

Randomly creates mazes which have multiple paths to solve. Entry and exit points for each path can be assigned arbitrarily. (I never seen this kind of maze anywhere before but I think calling them multi-maze should be okay.)

Snowflake Simulation Using Reiter Cellular Automata (Python)

2013-01-08T05:25:49-08:00

Python recipe 578390 by FB36 (fractal, graphics, math, mathematics). Revision 2.

This algorithm can create realistic looking snow crystals depending on the parameter values. (You can see good examples in the original paper by the author.)

I also added coloring.

Warning: Using current settings it takes about 30 minutes to run. I also do not recommend running it using IDLE.

Knight's Tour Map using Warnsdorff's Algorithm (Python)

2012-12-18T01:05:51-08:00

Python recipe 578386 by FB36 (algorithm, algorithms, graphics, math, mathematics, pil).

Solves Knight's Tour Problem using Warnsdorff's Algorithm for every square on the chessboard of arbitrary size.

It colors each initial square with a color that depends on the final square coordinates. (This is a method used to create fractals.) Many different formulas maybe used for coloring (based on abs/rel x/y/dist/ang).

Calculating each tour in full creates a highly chaotic image (and takes hours). So I added maxItPercent to cut-off tours earlier. (Using %10 creates an image that has both ordered and chaotic regions.)

Use PIL to make a "contact sheet" montage of images (Python)

2012-09-21T11:06:58-07:00

Python recipe 578267 by Hugo (graphics). Revision 2.

The Python Imaging Library (PIL) makes many tasks easy in digital photography. This recipe shows how to make a "contact sheet" of images, a single image with thumbnails of many different pictures. It's limited in that it will only work with pictures of the same shape, but you can make some really fun images.
