Nsided testing

Hi Michael,

I was playing around with Nsided and modelled a test surface with a 5 sided hole (see attached) applied Nsided patch and it didn't come out to crash hot so I thought I'd uploaded it for you to test other solutions maybe.

Anyone else can have a go and see if you can get a nice tangent continuous surface from all 5 surface edges :)

BTW I have one solution however it's still not perfect.

Cheers

Works fine here under OSX, with the standard settings in MoI.

Thanks for testing guys, Nsided works for me also however there are inflections between some of the surfaces, I believe a Nsided surface should be tangent to each mating surface in this case it's not.
The reason I posted it.

Cheers

Hi Danny,

> I believe a Nsided surface should be tangent to each mating surface in this case it's not.

As far as I can tell it seems to be tangent to each mating surface, a Zebra stripe analysis of the default generated patch looks like this:



Note there how all the zebra lines touch each other across the boundary lines? That means they are tangent.

I can see what you don't like about the patch though - but it's not that it's not tangent though it's that there's a kind of build up of curvature in a relatively small area near by the outer edges of the patch. Currently the n-sided patch mechanism has a tendency to do that kind of shaping, I do want to try to explore some different ways to reduce it.

Sometimes tweaking the "Bulge" factor can help.

- Michael

Thanks Michael,

Just thought I'd put it out there so I know what is actually happening at surface to surface juncture while testing Nsided.

Cheers
