My wish would be a Play button in GH, that then starts an iterative counter. This would allow GH to better deal with time-based or iterative simulations. Various GH plugins already use their own iterators, like Kangaroo, Quelea, ESO-BESO simulations, Anemone etc. If something like this was inbuilt, it would make it easier to understand and easier to modify and work with. Strange cables going from the right of the canvas back to the left could be eliminated. Images or videos, possibly rendered, could be saved automatically, camera movement could be controlled through GH. Or maybe just one variable changes over time and shows how a model can morph dynamically.
Like this, GH could very easily do all the things Processing now does. It could become something like the amazing ICE-tree of Softimage that got murdered by Autodesk. And it wouldn’t have to be too much of a programming effort, for the start just a counter with a frame count output, variables that can be changed from frame to frame, and a beautiful Play button at the top of the screen. The rest can come later.
Thank you very much!
