Not knowing much about Rhino, but knowing a bit about computer display technology, the answer is a qualified "that depends". The "jaggies" that you see are a result of the software package rendering the curve at a particular resolution and displaying it on a screen that is a cartesian grid. To smooth out those curves, the rendering can be processed before being displayed through an "anti-aliasing" filter. This will fill in the steps of the curve with pixels that are the "average" colour of the 8 pixels immediately around it. Many modern graphics cards can do this operation directly, thus saving the computer itself from having to spend its compute-cycles on display effects. So this anti-aliasing can be done either in the graphics driver of the operating system, or in the Rhino application. The computational effort required for anti-aliasing is really quite minimal for a modern workstation, so even if the process needs to be done in software, by the Rhino application, it shouldn't impact display times too much. There. I have just given my inexpert opinion. You need to look for an "anti-aliasing" option either within your operating system (Windows XP or Vista) or within the software application itself (Rhino). Hope this helps. Go Habs Go! /Jason
