Ask processing to redraw from a thread.

RedBolt

I have a thread which updates some objects i want to draw but how can i ask processing to redraw when the thread is done updating the objects?

GoToLoop

if you set noLoop(), you gotta issue redraw() in order to render the canvas!

Or just use a boolean blocking access to the updating objects, and when done, allow access to draw().
