algorithmic modeling for Rhino
Cellular Automata for Grasshopper
Information
CA4Gh is a framework for string-expression-based neighborhood-generation; a CELLULAR AUTOMATA.
This utility uses the gh-internal expression-parser; expanding it by pointing-operators and a 'Key-Value'-Database:
- T{...} OR Top{...}
- L{...} OR Left{...}
- B{...} OR Bottom{...}
- R{...} OR Right{...}
- TL{...} OR TopLeft{...}
- TR{...} OR TopRight{...}
- BL{...} OR BottomLeft{...}
- BR{...} OR BottomRight{...}
- nesting like: Top{... + Left{...}}
- all other variables are interpreted as a 'Key' and collected from the cell's database.
(detected from the gh-internal parser)

Hey Igor,
sure; u can do this.
Just set up the entrance-data with the setter in the beginning and go on.
As far as u use the syntax/operators of the gh-internal-expression-parser it should work just fine... So ur If(... , ... , ...) is fine; u can use ca_expressions everywhere there.
My Expression-Parser its just a framework which parse the given string to a valid gh-expression which takes the needed (Variable-)Values from a KeyValue-DataBase
I currently digging into this stuff again. Currently I am writing some code to enable n-Dimensional Cellular-Automate (2d,3d,4d,nd)... So, do not go too far with ur experiments, because the available operators (Left, Right...) are going to be replaced by a single one: Pointer{[,,,] ...}
If u want to do some beta-testing, let me know; I can send u a preview...

Hi Ortler
I it is inexact I have formulated a question. I wanted to ask whether it is possible to set two parameters (or more) as entrance. For example a - curvature and b - distance from a point/attractor. Expression could look so If(a<L{a} AND b>L{b}, (some value or expressoin), ........).
Thx
Igor

The Link to beta-1.1.0

Don't know why the link below does not work...

Hey Igor,
Just to say. This was and is a prove of concept: Its about the ExpressionParse. But its going to be fun to dig into possibilities. So...At the moment there is no edge, so if u think u are on the left outside, u aren't, u start again from the right.... (top/bottom == same)
I do not understand what u mean with array...
"{ aababbabbbaaabbabb ..... "
if u can give me some more informations about this, I will try to dig into it.
In the meantime, u could test the beta of 1.1.0 where borders are enabled; and some more, like 'parallel-processing' and 'generation-groups'

You couldn't explain how the plug-in processes data on the edge of the array. For example at the left border where value Left{a} doesn't exist. And also it would be desirable to know how to apply several variables in one array like as { aababbabbbaaabbabb ..... }.
