Reality Capture - Topogun - SubD

Yummy, I'd try to resolve this area to be more uniform

Does Topogun allow you to do quad patches?

Yeah definetly, I was still fiddling around with loops, but I already did yesterday after posting those screenshots, because that 3 to 1 was causing a noticeable bump after subdividing.
I also modeled the inside of the shoe, started to reshape the sole better, figured out a bit about the lace pattern and started to add tickness to the various layers of the main body.

It does and they are interactive, you can preview them and dynamically change the number of segments for each curve and change how the topology is arranged. You can create multiple patches at once, with 2,3,4 or more splines, join them and so on and so forth.
Once created you can't change them anymore, but you can edit them with the usual topology tools like move, extrude, draw, cut, collapse, brushes for soft move and relax and the usual stuff.

Very sharp.......................

Rich O Brien

Could you imagine if SU had these type of tools!

I'd love it. But it would completely cripple the viewport and user experience.

panixia

@Rich-O-Brien yeah, in Sketchup is hard to imagine this kind of stuff working in realtime.

For simple objects sometime I do some basic retopology using Tools on Surface, or Artisan Knife or Intersecting geometry, then extract the edges, weld and run QFT "create quadfaces from wireframes".
Another workaround is to pre-triangurate (with qft diagonals) small patches and then use the "Drop To" plugin to trow/conform them over objects.
I usually do those tricks for smaller portions of models.

For massive retopology on heavy meshes like this (this model is 120k+ vertices) I usually run Topogun (whith QFT oj import/export) then import back the base topology to refine and detail it using VT, Artisan, Edge tools, Qft, fredo corner, JPP, Flowify and basically every plugin compatible with quads (and basically whatever tool and plugin as long as I use the pretriangulation trick).

I did a quick video to demonstrate this tecnique a few time ago..

@panixia there are some awesome Vietnaniese plugins to copy\paste from\to SU\Max.
you could just paste to max and apply Retopo modifier (fully parametric, as we love it). Then continue in max or paste it back to SU

panixia

@rv1974 of course you have that Retopo modifier if you have a new version of Max..
But I'm still on older perpetual version..
Btw I have quadremesher, which is quite similar (but not as good as the modifier) and of course the "classic" manual retopology tools from 3dsMax in the "freeform" panel.

There's no need for Vietnamese Plugin because with QFT exporter/importer to move quad models back and forth between SU and Max.

The reason why I use Topogun most of the time instead of Max, is actually that the dynamic patches are sort of halfway between the speed of auto-retopo and the full control of manual retopo.
If I reacall correctly, only Blender has something similar in retopoflow, but the patches are limited to 3 or 4 sides.
In topogun you can have patches from 2 to whatewer-you-need sides, and they can be changed interactively.

@panixia Fantastic shoe ! Always amazed by your modeling.

panixia

@tuna1957 thank you so much!
I'm glad you enjoy this stuff

@panixia

yeah they significantly improved Retopo Mod:

also Conform is insanely good:

yeah.. I saw that.. amazing.

I also saw the new conform modifier, but I believe this video shows an updated/improved version.. looks good.

panixia

Let's go

Rich O Brien

Yay! Wrap-R

Looks like a fun texturing project too!

panixia

@Rich-O-Brien indeed

I believe I've just found a new trick to speed up that IDmask baking thing
(just some SelectionToy trick to quickly detect hard edges and split up surfaces without having to select too many loops manually)

panixia

Addictive..

Mike Amos

Brilliant and inspiring. Thanks for posting this.

panixia

@Mike-Amos thank you.. I'll share the last couple of models when I'm done

panixia

I had to put the shoe modeling on hold because I had to do this for work today

Rich O Brien

flawless
