Modular Multiplication in a circle

Welcome to Varomix Trix, in this series I'll show you tricks that I've learned along the way in my career, some are really simple but I think all of them will be useful.

 In this lesson we'll learn how to make awesome looking shapes using a simple method, Modular Multiplication is really simple still produces beautiful patterns.

    You dont need a Copy SOP, all the Points already exist, they just need to be referenced using a little Math....

    For your target point, change your Vex from:

    addvertex(0, prim, @ptnum * mult);

    to:

    addvertex(0, prim, @ptnum * mult % @numpt);

    I'm sorry, I forgot to say Thank You for this video. I learned alot.

      Thank you Daryl,
      yes that would make it way more efficient for sure,
      I wanted to go for clarity but I agree that makes it better and avoids
      having double the points

      thanks for sharing your code

        Please tell me, how I can add material and render it (program writes an error when i try rendering ) p/s I'm asking because I recently started learning this magic program

        • varomix 6 years, 9 months ago  | 

          Mantra renders curves directly, you can control the width of them adding a width parameter and adding color

          • astah 6 years, 9 months ago  | 

            program said( = mantra: Can't find geometry /obj/ModularMult/subnet1
            how do you think in what can be error ??

            • varomix 6 years, 9 months ago  | 

              that seems to be another issue, what is subnet1 doing?

              • astah 6 years, 9 months ago  | 

                I sent screenshots (with subnet1) to you in a personal message on facebook!

    So in this video you talk about combining both your processes to create an object that is manipulated by the music.

    I have spent like 3 hours trying to solve it and have yet to figure it out. I am wondering if you have a video somewhere that explains it so that I can figure out where i am going wrong. I am pretty sure that the I need to create a few more variables and use them to control the parameters that are made however, I can not seem to get it working.

    They are really amazing tutorials.
