[ANN] tkar

Discussion in 'Ruby' started by Joel VanderWerf, Aug 9, 2009.

  1. Hi, all,

    Tkar aims to be the gnuplot of animation — a quick and dirty way to get
    data from a stream or file into a window to see what is happening. It is
    more suited to animating discrete objects rather than numerical
    functions or arbitrary datasets. It would be ideal for visualizing
    output of a multi-agent simulation, for example.

    Tkar is now a gem on rubyforge.[1] Previously, it was a single-file
    executable.[2] The only dependency is Tk/Ruby.

    Tkar also functions as a simulink block, analogous to the plotter block
    and superior to simulink's native animation features. (You need to
    compile a simulink plug-in.)

    Here is a movie[3] made from one of the examples:

    (tkar has rudimentary support for creating such movies)

    [2] http://groups.google.com/group/ruby-talk-google/msg/4e0bece7cbda7984

    [3] this particular animation is from a tool for visualizing vehicle
    safety systems in which tkar was used. The tool was developed for an
    automotive company that citizens of my country are now part owners of.
    Tkar itself is free software under the ruby license.
