    This is what I am currently working on with LaserBoy.

    http://laserboy.org/convergence.mp4


    There are 4000 frames. Each frame is exactly the same line equation; a spiral made by 100 iterations around the unit circle and progressively linearly scaled from 0.0 to 1.0. The only difference between each frame is the number of vertices plotted along the line. It starts with 96 and ends with 303.

    This was rendered from the new version of LaserBoy Formatted ASCII Text.
    This is what it looks like in text:

    Code:
    math one_rotation          360.0
    math one_period            1.0
    math hues_shift_per_frame  3
    
    #    form       frames
    math lissajous  4000
    # amplitude   frequency   phase
      1.0         1.0         0.00
      1.0         1.0         90.0
    # duration    iterations
      100.00      96
    # amplitude   frequency   phase
      1.0         1.0         0.00
      1.0         1.0         90.0
    # duration    iterations
      100.00      303
    
    math cumulative_scale
    # from X Y Z
       0 0 0
    # to X Y Z
       1 1 1
    # acceleration
       0
    
    math render_form_span_hues 1.0
    It will probably take me just as long to document how the new text format works and how to use it as it has to write the code that reads and renders it.

    Would anyone be interested in getting a preview version of LaserBoy and experimenting with the new text format?

    That might be very helpful for me to write instructions. I already know how it works (I think).

    Nice! That reminds me of something.

    Here is the video link to my YouTube video I recently posted that includes several examples of the circular vertex swirl effect transfer function I wrote in Applesoft Basic back in the early 80's:

    It's a great visual pleaser, for sure.

    I had to come up with some funky math to make that animation move so smoothly. Normally one would think that the number of points plotted in a frame would be an integer. But that doesn't give you the fluid motion of all those frames in between. So I rewrote all the math figure functions to take a double float for iterations and calculate an interval step and a final remainder.

    ...and it worked beautifully.

    Thank you!

    You should try it out for yourself.

    Do you want to be involved in the testing and documentation?

    I wish I could. I just don't have the time, but thank you. (old man here, still trying to remember how to play with and/or update his old laser software).
    I spent a lot of time viewing your tutorials, and to be honest, there are a lot of "moving parts" to learn and remember. I haven't given up on it, just put it on a backburner.

    That's quite a jewel box.
