With Kangaroo’s Grab component you can do wonders. Proof is what @yelenaye built with Kangaroo and GH Player.
Of course, it’s showing GH Player which ends with Baking – If results of those actions could be saved and modified later it would take it to the next level.
As I mentioned when writing about Embedded Inputs (Wish: Linked & Embedded Inputs), there is a need for quick access to the VA Object settings not only by numerical input from the current UI Properties sub-panel but also graphically from the viewport – e.g. like when modifying the “Embedded” Curve.
Normal Kangaroo Solver (which allows Grab - Kangaroo Zombie Solver works, but obviously it doesn’t work with the Grab component) is not working inside VA styles, so temporarily running a simulation, moving a bunch of things, and freezing the result at the end is not possible.
The Grab Component method of course doesn’t have the precision of the and other goodies of the Gumball.
I don’t know how difficult it would be to achieve as much “Input freedom” as Yelen showed in their example inside VA Objects, so maybe something more like Autocad Dynamic Blocks with it’s widgets is a better example for now.
And how about Human UI?
It is pretty flexible. It would be fantastic if it could be used as an interface for changing parameters of VA GH Styles Objects.
