ACSLogo is a Logo Interpreter for Mac OS X. Logo is a popular language used to teach simple programming by guiding the progress of a 'turtle' which moves around a graphics screen. Despite Logo's simplicity, complex pictures can be constructed.
Simple commands can be used to make the turtle move in a straight line or change direction, and complex patterns can be built up from the simple commands using procedures and recursive techniques:
You can export the resulted graphics as TIFFs, PDFs or SVGs.
What's New in This Release: [ read full changelog ]
· On-screen graphics have been brought into line with the graphics produced when exporting to PDF. This means you get proper 'corners' when drawing a connected series of lines, and most of the performance problems which emerged with Leopard should have gone.
· New functions have been added - Wrap returns whether wrap is on or off , Shadow returns the shadow state, ColourAtPoint returns the colour of the pixel at the supplied co-ordinate.
· You can now export graphics as JPEGs and PNGs as well as TIFFs and a few other types..
· The Towards function sometimes gave the wrong angle; this should be fixed. A crash which occurred when opening a tutorial that is already open should be fixed.
