What I hate with smoothing is that areas get smoothed that are supposed to be square.
Jeroen, Paul-Jan: Will there be a way to tell DeleD a specific angle, like you do with lightmap smoothing, and it leaves the area that way without smoothing it? |
No plans in that area yet. How would that work exactly? [...] |
I've no idea how to implement that technically of course, but basically, it's just the same like what you did when you smooth lightmaps. You can specify an angle there and if the angle between two polygons that share an edge are lower than that angle, it will get smoothed, else it will keep that pointy edge.
So if you're got that cylinder
you'll get this maybe
instead of this

maybe it would be easier if you simply select the faces and then apply the smooth operator.
Just keep the top unselected |

This may be true in this particular case but if you've got more complex objects, things are getting annyoing quickly if you have to select every face or vertix (just to see that you're still not content with the result).

you had to use thresholds then
min < angle < max
angle is angle between face normals
maybe [20°,60°] |

As a first step, we could support a 'crease angle' option for the smoothing command. Next step would be true smoothing group support throughout DeleD (smoothing groups can also be generated from such a crease angle to get a nice set to start out with). Such a mechanism is required anyway for normal support (a feature long overdue  ), but we should then apply it to the smoothing operator as well. |
