Various Transitions
Hello All - nothing new or even sophisticated but rather a repetition of some geometry exercises which are shown and discussed in this thread already.
I've created a small kit (pic1 & transitions 01.skp) to make transitions easier for me. Meant here are things like pipe- or tree branchings, the arms of a Minion or Monster-Mike´s arms and legs (pic3) etc etc ...
All these transitions pass from a quad-face-body or -shape into an 8-sided "pipe" (which is my vavorite pipe shape somehow).
This kit even allows to combine different variants to one transition (pic2 & transitions 02.skp) - this results in the advantage that you can merge shapes with a different number of quad-loops (at least in a certain extent). Something like this always happens to me since I do not work particularly clean or planned oftenBest & I hope that this small "building"-kit may be useful for you too...

Nice schemetic views indeed!
Thanks for sharing.
Just like substances, I tend to see quads in everything now. Just a mental exercise.Now, I wanted to ask, is it a recommended thing to regenerate quads on quads?
I mean, let's say I model a raw mesh in several clicks, then apply a subD on it, then explode it, then remove some redundant loops generated by subD, add some new vertices here and there, subD again, explode again, remove some redundant loops here and there, tweak some crease values, subD again, explode again, remove some loops, etc. etc.
The objective is to be able to get rid of some redundant loops that only add useless polys and keep adding details only where that matters.
I'm pretty conservative in my workflow so I don't know if this is a common method as nobody seems to talk about this? -
Hi & Thanks!
hmm - probably I do not understand (translate) correctly wouldn´t it be the SubD process itself, which makes out of a simple raw proxy geometry a new geometry with too much loops then? - you'd also need a good computer, to SubD this new very large proxy then again ... -
Often subdivision creates redundant loops which are useless (basically in flat areas), and some geometry refinement where it matters (in round, convex/concave areas).
So I'm asking if I can get rid of these "useless" loops, and build upon previous subdivisions, explode and keep subdividing while simplifying the control mesh by removing redundant loops each time.
SubD is limited to 4 subdivisions I think, so this could allow for more detailed meshes.I haven't tried this "method" though, but was wondering if there was any problem with this approach of modelling.

I'd say it's all up to your preferences. The excess loops you're talking about can be annoying and resource consuming indeed. Since you can't prevent them from appearing, the only possible approach is the one you described and it's totally ok

It's something that's occurred to me before and I've tried to deal with it by adapting my approach to creating control meshes and also removing loops after subdivision.
I just assumed that there isn't a way around creating so much unnecessary geometry.

Yea, due to how the SketchUp API is - SUbD have to create entities for the subdivision. At some point during development I had a small polygon optimisation in that coplanar quads was not triangulated. But that turned out to be bad for performance when doing stuff like adjusting creasins - as SketchUp's Auto-fold have too much overhead when it kicks in. Also, in order to keep the subdivided entities in sync with the control mesh I cannot omit entities.
So as things are now you would have to optimise the subdivided mesh yourself once you are confident you won't need the control mesh any more.
Ideally I wish I could hook directly into the viewport - intercept how instances were drawn. But alas, that's not possible with the current API.

its been my practice to subdivide, and yes exploding at times, quadifying autofolded faces (takes a long time dealing with the diagonals).. It can be a pain with complicated meshes
. .. Even with perfectly done quads can all of a sudden triagulate when you toggle subd.I wish autofold can be totally disabled..and wish loops can be moved by dragging instead of adding and removing...
-
Would it be possible to have a tool similar to crease, where you select two loops and SUbD doesn’t subdivide between those points?
Thinking about it, that sounds almost impossible to implement....just throwing it out there.
