Python recipe 580495 by FB36 (fractal, graphics, image, images, math, mathematics).

Random Planet Generator using 3D Plasma Fractal and Voxel-based Ray Tracing for rendering.

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.

Python Mandelbrot Fractal with Tkinter (Python)

2015-05-06T09:57:27-07:00

Python recipe 579048 by Antoni Gual (fractal, graphics, python, tkinter). Revision 9.

Displays in a Tk window a pretty coloured 640x480 Mandelbrot set in 6 seconds. Calculates each one of the 300K pixels with a maximum of 256 iterations.
Only Tkinter used. Tested with Python 3.4
I will test any contribution and add it to the code if worthy.

Animated raster graphics demo in Tkinter (Python)

2015-05-05T20:26:41-07:00

Python recipe 579052 by Antoni Gual (animation, graphics, python, tkinter). Revision 4.

EDITED: A small animated graphics demo in Tkinter, displaying a 1990's style Rotozoom, more interesting than the TV snow I posted previously. The Tkinter management part is just the same. The code is a little longer as some trig tables must be precalculated for speed. The window size corresponds to the resolution of the old DOS screen 13, as I originally coded the demo for Qbasic.

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.

Mandelbrot Fractal using Tkinter (Python)

2013-07-06T23:53:20-07:00

Python recipe 578590 by FB36 (fractal, graphics, math, mathematics, tkinter).

Mandelbrot Fractal using Tkinter

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).

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.)
