algorithmic modeling for Rhino

Hi guys

i´m tryng to replicate the "drawing machine" system in gh

please see

https://www.youtube.com/watch?v=BG9e06IWAxE

(min 5:09)

everything is fine, but there is something that i havent been able to solve

-the center disk rotates in the xy plane, and and want to record the data of the points generated by the intersection of the 2 arms

but the points are not drawn in the rotating disk, as it rotates

they only draw in one area, as if the center disk did not rotate al all

i´m attaching my definition

thanks for your help

cheers

You worked with points,
you needed to do with UVpoints (disk surface).
I remade the algorithm, needs "Count" of the Generation component

It's very easy to do this with Anemone (with a total respect to the initial code).

I'll post the definition as soon it's ready (and easy to handle).

best, Peter

thank you peter, looking forward to see your solution

Well...

... When I've started adding the Anemone thing, I said to myself: peace of cake: this is 10 minutes work...

... but since kinematics is my weak spot...hmm...the one thing brings the other (for instance the ability to create and display  a collection of solutions related with the kinematic geometry etc etc).

So for the moment get the stupid version : the Anemone (acting solely as a "counter") feeding the record component (should be eliminated in the next update).

Don't touch the inactive outer Anemone loop (but you can play with the demo included that is irrelevant to this case).

more in a while

best, Peter

Hi peter

Thanks so much

As far as i see, the demo is operational for now right?

No it's not because the main disk rot angle is not invited to the party (but that is very easy - this is the reason that I've provided the other "independent" demo).

More soon

BTW: I've not included the main disk rot factor to the "pen collection of points" because ... er... I was out of cigars and without them I can't think a thing (or two) he he: in plain English I've forgot it.

The finished thing (approved by NASA, DARPA, BBC, CNN and IMF)  soon

Here's some working thing : some "progress" (kinda) is made but it works. Outer Loop (still inactive) needs some work more.

TIP: read comments inside as regards triggering the inner Loop when changing (via sliders) the whole geometry.

TIP: by adding a Z move option (like the independent demo included) That way you can have a 3D curve (ideal for planet Utopia and/or Zorg).

NOTE: the "solid arm maker" (the cluster) is somehow faulty ... but why bother? (or spend some time to pin the issue(s)).

be the Force (the dark option) with you

Thank you so much dani

Am i wrong but it seems that regardless of the central disc rotation the "drawing" is not captured by it?

Should´t you get a pattern that is "spread" around the whole disk?

as seen on the video

saludos

Hi guys

this is simple variant with Kangaroo counter......

Attachments:

Truly excellent approach (but where's Anemone?  - that's from the promo section, he he).

best, Peter

hey igor, this is great thank you so much
