This version is based on JavaScript programming. Simple commands Turtle Graphics works by issuing commands to a “turtle” which moves on the screen to draw a figure. All commands are from the perspective of the turtle. The commands look like: // comment to explain what is going on, from the double slash to the end of the line http://kirk.fun/turtle-graphics/examples/ Mon, 01 Jan 0001 00:00:00 +0000 http://kirk.fun/turtle-graphics/examples/ Warning This page is currently a stub. The true example can be found here Overview This page contains examples of the graphics generated with the turtle graphics program. This is a pictorial index, so clicking on an image will bring up the Turtle Graphic IDE loaded with the program to generate the image. The description of the example tells what inspired the example, where more information can be found, or where similar things can be found. http://kirk.fun/turtle-graphics/guide/ Mon, 01 Jan 0001 00:00:00 +0000 http://kirk.fun/turtle-graphics/guide/ IDEs or Integrated Development Environments allow a user to write and test code on a single page. This IDE allows a user to write JavaScript code with Turtle Graphics functions and see the graphical results. code and test it on a single web page. No other program is required. Just a modern browser that can support HTML5 like Chrome or Firefox. Some older browsers may not work. The IDE screen is divided into four main areas: http://kirk.fun/turtle-graphics/animation/ Mon, 01 Jan 0001 00:00:00 +0000 http://kirk.fun/turtle-graphics/animation/ Warning This page is currently a stub. The true animation tutorial can be found here Overview This tutorial will take you through the basics of drawing with turtle graphics through the creation of the motion of stars as seen from a space craft exceeding the speed of light. This is a journey, but like all journeys, it has a series of small steps. In preparation for the journey, it is assumed that you already have some knowledge of JavaScript and Turtle Graphics.
