What is OGLsprings

OGLSprings bases on the famous xspringies program by Douglas M. DeCarlo (dmd@gradient.cis.upenn.edu) but unfortunately it hasn't all of its functionality. You can create a spring - mass - system and the program shows how it behaves. You can change the masses and spring values to change the behaviour of the spring - mass - system.

Sorry! You need a hardware accelerated OpenGL driver as http://www.nvidia.com/Products.nsf/htmlmedia/software_drivers.html to use this program reasonably. Otherwise the speed is too small :-((.

The main new feature is the 3 dimensional room performed by OpenGL. Furthermore it has a Tcl/Tk interface.

Unfortunately there is no edit mode :-(( (it will be!) but Version 1.x has an edit mode. So you can create a spring mass system interactively. Furthermore you can save and reload the created scenes. OGLSprings accepts a similarly file format as xspringies. The 2 main differences are:

• The masses have a Z coordinate and a Z velocity
• There is a new keyword mast followed by the X/Z coordinate and the height of a mast. (See bsp.xsp)

Download oglsprings-1.4.tgz and follow the instructions in README file.
