Hi Brian.
Maybe some of this will come in handy.

Thank you WN.

Hi Brian

Check the attached "Event.js" file.
I added a reset input to "Quartz" node. Now, it resets the value as well.


You can use "Degree To Radian" node before angle input to convert Degree To Radian and vice versa.

I tried to make a nod without knowing the math.:)
Anyway, Hope that helps

Hi MO,

Thank you for the updated reset for Quartz.
Attaching the push button switch to reset input, with second terminal set to 1, and pushing the button, does the reset.

Node of whirl with (only) 4 child ellipses, range 90 to 180 degrees.
Over 180 degrees, they expand beyond parent ellipse0.
Tilt angle should be Modulus 180.

I'm not happy with behavior of Quartz.

I might try a script.

The axis RATIO is the same for all child ellipses. Just apply it to the widths and heights of the parent of the child.
Widths and heights get swapped every generation.
Ellipse[i] is the parent of child[i+1]
Ellipse[0] could also rotate, as the child of ellipse[-1]
Ellipse[i,j] could use j as the scaling index...
The step angles of a scaling ellipse for child 2 is twice that of child 1.
The step angles of scaling child ellipse 3, is 3 times that of child 1.

Nice colors.
I tried trimming, but Planar did not like slivers of arcs.

So maybe just make each ellipse a different planar style?

Hi Brian.

re :

Yes, it is.
