<p style="color: grey"> Python recipe 325391 by <a href="/recipes/users/1461790/">Rick Muller</a> (<a href="/recipes/tags/graphics/">graphics</a>). </p> <p>This code snippet uses Python/OpenGL (<a href="http://pyopengl.sourceforge.net" rel="nofollow">http://pyopengl.sourceforge.net</a>) to open a window using GLUT, and draw a sphere into it. I've used this many times as the starting point for more complicated applications.</p>

<p style="color: grey"> Python recipe 205451 by <a href="/recipes/users/860809/">Simon Burton</a> (<a href="/recipes/tags/graphics/">graphics</a>). </p> <p>Here is a relatively simple framework for making povray files from your favourite programming language, python. It's good for creating structured/mathematical scenes and animations.</p>

<p style="color: grey"> Python recipe 266466 by <a href="/recipes/users/135731/">Paul Winkler</a> (<a href="/recipes/tags/graphics/">graphics</a>). Revision 2. </p> <p>You have colors in a number of formats (html-style #RRGGBB, rgb-tuples (r, g, b), and PIL-style integers). You want to convert between formats. It's pretty easy to do, but also pretty easy to forget; hence, this recipe.</p> <p>Just for kicks, we'll extract an RGB tuple from an image file at the end.</p>

<p style="color: grey"> Python recipe 440588 by <a href="/recipes/users/786815/">Robert McDermott</a> (<a href="/recipes/tags/graphics/">graphics</a>). Revision 3. </p> <p>The gen_captcha function generates an image containing text that’s easy for a human to read, but difficult for a computer. This allows you create a test to tell humans and computers apart. (requires PIL)</p>

Revision 2. </p> <p>Random maze generator using depth-first search.</p> <p>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.)</p>

<p style="color: grey"> Python recipe 362193 by <a href="/recipes/users/1461790/">Rick Muller</a> (<a href="/recipes/tags/graphics/">graphics</a>). Revision 2. </p> <p>This package does simple polynomial manipulation: adding, multiplying, taking to powers, evaluating at a value, taking integrals and derivatives. Nothing as sophisticated as Mathematica, but useful all the same. I find that I make lots of dumb errors in multiplying out polynomials by hand (when I don't have Mathematica at my disposal), and this little script helps prevent those errors.</p>

Also the rand() function generates a number between 0 &amp; 1. That's why one would multiply by 10 or 100 or 1000, etc..</p>

<p style="color: grey"> Python recipe 343386 by <a href="/recipes/users/1461790/">Rick Muller</a> (<a href="/recipes/tags/graphics/">graphics</a>). Revision 2. </p> <p>This is a little script that uses Python to generate the cellular automata that Wolfram discusses in his book "A New Kind of Science". The script uses the Python Imaging Library to render the output, but you could replace this with text or any other method of visualization.</p>

<p style="color: grey"> Python recipe 412982 by <a href="/recipes/users/1461790/">Rick Muller</a> (<a href="/recipes/tags/graphics/">graphics</a>). </p> <p>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.</p>
