SubD examples and models

Had SU known only about the control mesh then any tool could edit the mesh while the viewport displayed the subdivided result.

You explain things better than I do!

This is what I mean; is there a way to show the subdivided mesh in a small window that runs real-time with the SU model?

You would simply play with the control mesh in SU and a window shows a subdivided version that moves in real time with the SU model? When you rotate, zoom and orbit the subdivided "render" does so too.

Then when you are happy you can do the final subdivision inside SU right at the end.

Oh, well, that surely is the next thing I'd poke into once OpenSubdiv is implemented! I was thinking of it in two stages:

A preview window on the side.
Make the background of that preview window transparent and overlay it the SU viewport. (not sure how well that'll work since it'd be a separate 3d spacxe on top of SU's view...)

Nice!!

I thought I was talking jibber jabber but you catch my drift!

Can't you already do something similar with Maxwell? It renders a subdivided version of your control mesh? I'm not maxwell user so unsure. Also needs to be realtime, simple shader.

If you could switch between SU viewport and a SubD render overlay that would be better.....kinda like Thea where you can see the render in the viewport. If you could press a hotkey and the screen changes to the subdivided render that would be a total game changer for SU.

Even if it was a preview window I would be happy to be fair.

Yea I wonder if I saw a YouTube video on that. Though I'm not a Maxwell user...

Please, no separate window!

Yes, Maxwell has render time subdivision. It's not a shader, it's a modifier, that produces real subdivision geometry.

Not much way around that - since the SU API doesn't give access to the pipe-line. It'd off course be optional to use it.

Not quite sure where to post this but, since I'll be applying SubD on it, I'll ask here: any ideas how to fix the topology of the red section in this model?

Maybe add another loop.

ZahariStoyanov · 3 Apr 2016, 08:07

My biggest concern is the rear glass' frame - the corner looks a bit weird when I subdivide it because the ring from there goes along the roof all the way to the front instead of connecting somehow to the door's corner or something. I mean, I'm trying to solve the way I did on the corresponding front section(A-pillar?)

ZahariStoyanov · 3 Apr 2016, 11:36

Fixed! I color-coded the problematic section again so I can better explain what was running through my head: I'm looking at the whole front-to-back edge as a group of rings that go along through the whole car. The issues shown on the "before" picture caused the corners between the roof and the C-pillar to kind of flick open. Now that I rearranged those rings and added a little extrusion to all contours, the problem's gone

After:

Well, here comes mine:

and after a little bit of Thea and Photoshop, this is the result:

Very clean high poly modeling!

Images doesn't seem to load on my end. (IMO it's better to upload to the forum instead of hot-linking.)

It's Spanish and I don't see the images too.

Nice! That looks to be similar to the challenge HornOxx and I was looking into earlier:

o.k I know it's not a car or godzilla, just started messing about with SubD last night. trying to wrap my brain around a new way of doing things. here's a mod style chip & dip bowl for your next party. copied my steps for the pic.

plain cup in front pretty much native SU tools

far left, base shape of bowl , pretty much Vertex tools

middle bowl , shaped wavy edge , all Vertex

far right , SubD , copied and scaled down for the dip.

I think I really like this, don't think I could have got these shape without Vertex & SubD , thanks thomthom..

So just when I managed to stop checking to see if there were any updates in the UnWrap thread, you post one here... Pretty sneaky... Pretty sneaky.

Damn it, I built a time machine just so I wouldn't have to wait for this to be released... But either it doesn't work and I keep falling asleep in it or it only moves me forward in 8 hour increments. Stupid lousy impatience.
