SubD examples and models

Rich O Brien

one the hardest transitions to tackle in subd is the pipe perpendicular to a pipe. the poles (5 star) cause the pinching and irregular shape.

Funny you should mention it Rich, but that's exactly what I had to deal with the other week.

The general opinion is that you have to increase the detail (segments) of your cylinders.

And a here's a quick render.

when then pipes meeting the surface are smaller than the parent it's tough to keep things cylindrical.

i wish there was a Spherize extension for SU like Blender has.

this is a good model example Hieru thanks for sharing!
In addition to the model´s complexity itself I first assumed that you had managed to make a screw thread inside this cylinder

Yes, I had to rework things several times until I managed to maintain the cylindrical form.

Thanks!

I'll put my hands up and admit that I cheated on the threading. It really wasn't necessary, so I just used a saw-tooth profile. I've done SubD threading before but didn't really have the time for this model.

I wouldn't call it cheating. No need to use SUbD where it isn't needed. (Or any tool for that matter.)

What I mean is that I used a saw-tooth profile rather than threading on the control mesh.

In theory I could have used various modelling techniques on this and combined them, but SubD seemed like the best tool for coping with all the more difficult aspects at once.

I even tried doing this in Moi first - because I was under the impression that it was supposed to be easier to model this sought of thing. The basic form with the tubes and 50% of the bevelling worked a treat, but it crashed and burned when it came to some of the more complex bevelling (where the small tubes meet the base).

Hi
quite similar to Cotty´s example just right above I recently tried this tree-like structure,
which is complete based on an octagonal geometry - This allowed me to start with only a halved
tree first
The first finished "branch fork"(?) I scaled, rotated and varied a little before mounting it to
the previous one then...
