    Default Abstracts...my Way :-)

    Hello,

    Abstracts are not as popular here in Germany as beamshows and also I have not invested
    much time in Dynamics to change the existing one.
    Like all LDS derivatives also Dynamics has the Lissajous - Generator
    as originally programmed by Lennart Wietzke.
    But I think few people really understood it.
    So I looked for another way to create similar figures.
    Loop events would have been one way but also a prism function works.
    If you look into it a bit more you will find many more possibilities.

    If you are interested in abstracts generated by math, you should check out LaserBoy Liquid Math.

    https://laserboy.org/LLM.txt

    It is a script language that allows you to use LaserBoy Oscillators as function objects in an animated 3D vector art (function graphing) calculator.

    It's sort of like an emulation of an analog abstract console.

    Here are some example videos. Not all of this is Liquid Math, but most of it is.

    https://laserboy.org/mp4/

    There is also a script language for rendering animated vector fonts.

    The LaserBoy zip comes with documentation and example text files that you can open and render in the LaserBoy application and also read in any plain text editor.

    Hello James,
    I am of course familiar with the mathematical principles of Lissajous.
    The theoretical possibilities to influence the oscillators are almost infinite. I think I just have to try a bit more what makes sense and what not.
    I am a little over 50 years old and I have given my first Lissajous generator from a 2mW HeNe laser
    and 2 DC motors a mirror adjustment similar to the linkage of a tail rotor of a helicopter :-)

    But to generate "nice" figures it needs a bit more than 2 phase shifted sine - signals.
    Realtime offers so many possibilities in the generation of the base frame, Surfaces, DrawIn/Out, movements etc..

    Hi Guido.

    Well, I just turned 57 and I have been exploring parametric line equations to make interesting art for more than 40 years.

    Liquid Math is a culmination of all of my experience and quite frankly a lifetime achievement.

    It's a way for others to explore this space that has an interface. It does not require editing the equations as part of the program's code. It does not require understanding C++ (although that is helpful). It does not require compiling the code to run the equations.

    It does require some imagination.

    But it can also give you a much better understanding of how periodic functions can be used to make 3D line-art math sculptures.

    Laser display is nice, but it's also a lot of fun to just use the LaserBoy application to explore and view the art you can make within it (in full color animated 3D).
