Nutcracker Models / Re: Snowflake X/Y vs R/Theta geometry

« on: January 01, 2015, 07:42:39 PM »

Steve,

Thank you for the insights.  So what I am starting to understand is that since the coro flake is a unique geometry you have to in a sense transform (in your head) simpler geometries and apply them to the flake.

For case 1, your example of bars,  I am imagining you just start numbering you pixels from the center out on any given arm and then keep counting up arm after arm.  So first arm is 1 - 10.  2nd arm is 11 - 20. etc.  The nutcracker does its magic in scanning the square matrix in a bar pattern.  This can apply linear wipes, (up or down) and the like.

For case 2,  I can visualize the concentric expanding effect and then sort of a little spin around the outer sub- flake (or flaklet).

For case 3,  I can visualize the wagon wheel if you had a sort of chase with a chase group of 10 pixels.

How have you numbered you pixels as you get to the outer flaklet, do you just run around the points sequentially and always in the same "clock-sense"?

I know there is a long list of future feature enhancements, possibly there could be some effects specific to radial type geometries.

Thanks for your comments and helping me grasp these concepts.

Nutcracker Models / Snowflake X/Y vs R/Theta geometry

Nutcracker wizards.
I'm a newbie so forgive my vernacular if I get a few terms wrong.   I have a coro snowflake that I would like to apply models / effects to.  The geometry of the snowflake is 5 long radial arms with a smaller 5-spiked radial snowflake on the end of each long arm.  (This is much easier to look at and get the idea than to describe.)  So it seems to me that the nutcracker effects are mainly designed for rectangular X-Y type geometry (and they are great).  The snowflake is easier described by radial (R theta) geometry.  So, for example how do I model and get an effect where each leg might sequence around and then each smaller (end-flake) also circle around? Sort of like a ferris whell.  I know I can sort of reorder this visually into a vertical X-Y matrix - but visually the nutcracker effect looks much different in a X-Y geometry as compared to radial geometry.   If you have had luck with snowflakes or have alternative ways that I should think about this - I be glad to hear your thoughts.   Does nutcracker use different geometries or are all effects basically applied to an X-Y matrix?

Thanks for helping a NOOB.
