generative modeling for Rhino
Vicente, for this I use a script component...feed the tree into x (tree access) and then in the script:
A = x.PathsIf all you want is the paths, it does the trick. It is a workaround...not a full solution...
David has explained this previously here: http://www.grasshopper3d.com/forum/topics/sluggishness-of-param-vie...
If you don't want to bother with scripting, you can even just cluster a param viewer to get the paths with no lag in display.
Well, don't get fooled by the high number. My laptop screen refresh rate is 60 fps, so anything I try to draw faster than that suffers from a lot less overhead since two Repaint messages that occur closer together than ~17ms are swallowed and you only eventually get a single redraw for them.
But anything over 40 or so feels completely smooth so, yes, it's good news.
PathMapper display is slow? That's odd as it shouldn't draw much on the screen (unless you've defined hundreds of mappings, which I doubt). Can you post a mapper that repaints slow?
