tgsjo is a script for jQt patterned after the graphical aspects of the Logo programming language. Turtles exist in a 3d environment projected onto a 2d canvas.
tgsjo is available at https://github.com/zerowords/tgsjo . However that link is not needed because the following command in jconsole or jqt puts the tgsjo scripts directly into your addons directory. install'github:zerowords/tgsjo' After that install, a Lab *tgsjo.ijt* can be run with the following 2 commands in jqt. load'labs/labs' lab_jlab_ jpath'~addons/zerowords/tgsjo/tgsjo.ijt' Without Raul's exceptional contributions tgsjo would never have been created. Raul not only explained and implemented much of the openGL, but contributed the quaternion code for controlling turtle movement. Raul is also the creator of the mechanism that makes it possible to slow down the graphics when multiple turtle actions are programmed. I believe Bill Lam contributed the code to link J and openGL. Lots more can be done. -- (B=) ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
