Tessellation

Dec 12, 2006 3 Replies

This problem has been annoying me for the last year so I hope someone has a few ideas on it...



In order to get rid of tessellation in models you go to.. Tools>Options>Performance>Image Quality and put the top slider to a maximum, check 'optimize edge length'. Often when I do this I still have tessellation in the model (doesn't matter what size the curve is that I'm looking at).



I need to get rid of this as I'm doing a close up render which should show a nice curve.



Hope someone can help,



Thanks.



is this just a lone part, or a part in an assembly? I wish I had more to add, but I haven't had problems in parts, just parts in large assemblies (and we can get into that if its the case - there are some neat workarounds)

If it IS just a super-duper-close-up of a part that is causing you problems, here's a notion off the top of my head that I would at least try if I were in your position: I suspect that tessalation is based on the model size. If it is a super-super closeup that you desire, I would test cutting away the rest of the model that won't be in frame. My hypothesis is that smaller model=smaller tesselation. I don't know if it will work, but I know that's the first thing I would test.

Let us know how you fare, Ed

Yep, large models with small features are a problem. They use a global setting based on the size of the part. What they should do is have a check box for using an adaptive tesselation. Like an adaptive mesh for FEA or STL. The local chord length is based on feature size.

-Graphics/Quality

-Dynamically increase tesselation while zooming in

-Parts and Assembly with many radii, freeform Design Parts and round shapes often tend to provide a poor display quality when zooming in closely, as the tesselation-threshold is set to a fixed maximum value (which is determined by SolidWorks) in the document properties. This makes it often difficult to evaluate modelquality and desired results.It would be a great thing if solidworks would dynamically increase tesselation in the areas visible inside the graphics window when zooming in and decrease the tesselation again when zooming out - this would ensure that rounded edges always appear smooth instead of the polygon-look that you=B4ll get now.
