Real Time GH Progress

I wrote a bit about how I develop real-time dynamic systems using GHPython here:

Sticky variable alternative

Yes that’s exactly correct, I find it much simpler for encapsulating local persistent/dynamic logic (than sticky). I’d advice against using global and instead either have class methods/functions input, return and overwrite (append, manipulate, whatever you need) persistent variables you’ve instantiated within the if "foo" not in globals(): scope. Remember, this data can be anything. Leading to the second option: instantiating instances of your custom class as persistent variables, and then ca…

With a very simple example here (of making a persistent/static mutable variable and updating the component at an interval):

GH - No screen update while in for-loop

In that case I would suggest scripting the update (enabling you to check things before updating, activate with a boolean toggle etc). Attached a minimal working example of this: 170531_GHPython_Timer_00.gh (3.2 KB) Edit: Just tried “baking” something downstream from the counter/update component, this appears to work as expected, but I suspect this could cause concurrency issues depending on the specific case: 170531_GHPython_Timer_01.gh (4.0 KB)

I’m reading up about Kangaroo. It seems to offer the vast physics solutions, but I’m not sure how it tackles the problem I raised.

Here’s an example of how one might implement a live Kangaroo2 solver in GHPython:

How to calculate and display in real time while calculation in GHPython?

Attached an example of a live Kangaroo2 solver implemented in GHPython (note: it will be slower than the standard component). While one certainly could use sticky (like for instance what we did for the ShapeOp GHPython implementation). I’ve personally quite come to like the if “foo” not in globals(): method for creating persistent variables, as they will only exist within the local scope of their individual component (ala the static mutable variables one can make in the C# component), and is ar…
