Java Tutorial: Mandelbrot fractal applet in grey - Part 6

Java Tutorial: Mandelbrot fractal applet in grey - Part 6

Posted in Development

In this ShowMeDo John builds on the foundation laid previously to generate and display the Mandelbrot fractal in a Java Applet, as a further example of how to perform pixel level rendering. This video shows how to build a gray-scale Mandelbrot (colour comes later). Some of the source code for this tutorial is available in our wiki(JavaMontgomeryAppletSeries).An example of an interactive Mandelb...

Java Tutorial: The 'Hello World' Applet - Part 5

Java Tutorial: The 'Hello World' Applet - Part 5

Posted in Development

The standard Java graphics library does not contain a drawPixel method, but there are plenty of ways to render graphics at the pixel level in Java. In this ShowMeDo John makes use of a BufferedImage so that an array of integers can be used as pixels for rendering on screen. See additional information and source code in the wiki(JavaMontgomeryAppletSeries). Video is here.

Introduction to PataPata

Introduction to PataPata

Posted in Development

The PataPata project is an experiment focusing on taking ideas from Squeak and Self and moving them to Python, as well as trying to go beyond the ideas in a Pythonic and educational constructivist way. It also aspires to help people build microworlds and other learning tools for the Python platform, using a prototype-based programming approach.

Learning Recursion with RUR-PLE

Learning Recursion with RUR-PLE

Posted in Development

In this ShowMeDo, André Roberge discusses the concept of recursion, starting from the simplest example and ending with a graphical solution of the Tower of Hanoi puzzle using RUR-PLE. The importance of ensuring a proper termination condition and the pitfalls associated with an overly large number of function calls in generating Fibonacci numbers are also covered, as is the topic of memoization.

Introducing the RUR-PLE Learning Environment

Introducing the RUR-PLE Learning Environment

Posted in Development

RUR-PLE is a programming environment designed to teach Python, somewhat akin to what Karel the Robot did for teaching Pascal in the early '80s. RUR-PLE includes a series of tutorials with various programming exercises. In this ShowMeDo André Roberge gives a brief tour of RUR-PLE, introducing the lesson browser, the editor, the Python interpreter and the robot world. This ShowMeDo concludes with...
