Smoother Curves

[a1harps]

I have been using loft along a path to create some curved solid objects.

 

When I render the objects with or without material, the curvature looks very smooth within the boundaries of the object but the outside edges appear somewhat jagged.

 

I have noticed the same problem along curved edges of other solids in renderings even when the curved solids were created by other methods besides loft.

 

What can be done to make the edges along curves in renderings appear smoother?

Viewres

Facetres

Dispsilh

Regen

-shademode g

Post an example if you can't get results you are after.

Try a setting of 10 for Facetres.

Set your Smoothing angle to a higher number on your render screen (AutoCAD 2006 shown, but I think it appears the same in 2004):

 

The "Smoothing Angle" is saying "Anything with an angle that's LESS degrees than the number shown, should be smoothed out"

 

What works best for you will determine what your needs are.. the more smoothing the renderer has to do, the longer it SHOULD take to run the render. but since there's MANY less faces/polygons to figure out, it ends up taking less time.

 

However, if the segments are large, it will just round the corners and leave the series of straightaways.. the impact of that depends largely on your scale. Find the balance that works for you.

That worked great Mark!

 

It looks like the default for "facetres' is .5......does leaving it set to 10 slow things down?

 

 

@JD.. thanks for the clues..do you have any recommended settings for those?

I set Facetres to max 10 in my template. I don't do a lot of parts in an individual file, so I don't see a slow down. If large assembly look into xrefs.

 

I set viewres to 2000 in my template.

 

I turn dispsilh off (or is it on? whichever one gets rid of the diagonal lines - see I set all of this stuff in my template and forget it). Also turn off solidhist (for other reasons)
