Here’s what I don’t understand:
I just made a nurbs model of a sub-d bike I made and the result is 9800 nurbs surfaces.
(workflow not important, but just so you know where the surfaces came from)
If I in rendered mode has edges and curves turned off and run testmaxspeed it takes 14 seconds.
And then I extract the rendermeshes of all surfaces and hides the nurbs and run testmaxspeed it takes 3 seconds…
So why is Rhino calculating all the nurbs data that is not seen? It just doesn’t make sense to me. All it does is moving the camera, and showing the rendermesh, so to me this should be just as fast as the extracted rendermesh.
None the less, I wish we could have a mode that just shows the rendermesh when manipulating the view, and then calculate the nurbs data when the camera is still. It would be a good hybrid mode for most of my needs for a fast display mode.
