Since you were looking for ideas, and IF I can make a humble, and perhaps unreasonable, suggestion: Your car experiment brings to mind the idea--what if vertex tools could be made to work on one side of a locked plane or set of edges so you can freely work on a half model.

You mean like for mirroring a mesh? For that I just use components. (Or maybe I didn't understand the request... )

if you are modelling in quads you can easily select only the outer ring, then turn off soft selection and scale it to 0 on the mirror plane.
e.g. if your mirror plane is parallel to red/blue axis then scale the last ring to 0 on green axis so you can properly match the two mirrored component.
just an idea..

Hey, that's a neat little trick. I was mucking about with intersection and thinking I had to add a tool that projected the vertices to a plane.

panixia

would be nice.
also IF i may suggest, i think you have the tecnology to improve/expand a bit the make planar tool. looks like it makes planar only on a "average" plane wich is useful in many situation. but would have been also nice to have option to choose the plane, e.g. red/greenn red/blue /green blue. that can be helpful.
but maybe the trick to scale it to 0 can work also for a selection wich is not a simple ring, now that i'm thinking of it, i should try how it work..

yes, i tried. it does.. so no need for additional tools/option. the gizmo does it all!

thomthom

I love it! I love it when users find good tricks like this which I hadn't even thought about.

panixia

yeah man, the point is your tool is f#kin' amazing! can't stop to play with this in the sparetime.
yes sparetime.. i mean: i'm modelling those boring small houses for the boss.. boring bloky squared-out-at-all houses.
so i have to test your organic tool in the lunchbreak..

i hope the days will come for a detailed fully organic-objects-loaded vray render..

panixia

not sure i fully understand what's exactly the matter with your door shape, but if the point is to avoid triangles from loops while having the crested shape to smoothly "vanish" into the main door shape, then this is my try at it with VT+QFT.
no reference image/size.. just thinking of the general loops arrangement for such a shape..

It's not the crested shapes that's my main concern. It's the different detail lines that flow into each other merging multiple surfaces.

Haven't tried anything yet. Been ill and got distracted by subdivisions. Time to get back on track.

panixia

now i see.. the "critical intersection" is quite hard

Ok - now I promise to get back to modelling.

hellnbak

Jeez, I would love to be able to use this on my cars. I could stop spending half my time trying to smooth everything and spend more time doing actual work. I see this is a menu item in your SU, so is this a plugin we can download yet? I'll pay

panixia

looks great!
i didn't understand from the vid if it is possible to crease in your beta! great job anyway!
here is my super-crappy effort to the door topology.. never tried to model cars before.. looks very difficoult indeed..

So it looks like you can bring the center edges in line again, by selecting all and scaling to 0 with the scale tool. but there doesn't seem to be control of where this new plane is. You still have to bring it back to the mirror line periodically, changing the work you've done in that area. Or am I missing the technique?

being able to lock edge vertices and nearby unconnected geometry --maybe this is a discussion for the plugin thread.

It's just an experiment I've played around with the last couple of days. Nothing that should leave the confinement of the guinea pig testing area. There's lots to do to make this safe to the public.

No - so such thing as of yet. I'd have to learn that the Catmull-Clark thing do first. Implementing it is easy - understanding it is a different matter.

You have the crest shapes pretty much there. But you're missing the design lines that flows with the yellow edges. Notice how they intersect and blend - especially at the top. I'm thinking I need a loop to run across the door from the top where the front and back fender meets along the crests.

yes you have to bring it back.

not 100% sure about this.
in the original comment i said "outer ring" i wanted to say outer loop. in that case not so much would change in the geometry after scaling 0.
i mean place back the component on the other mirrored one require 2 click: pick endpoint -> snap endpoint
i suppose a lock plane tools would need at least 4 click: show menu, enable mirror plane lock, pick first point for the plane, pick second point for the plane.
so..

it is absolutely not proportional cause i have no dimension, but i think the job of the upper yellow line may be done by the red faceloop.
by twisting it from near vertical to near flat, should be possible to remove the triangulation on top of your first picture (the one with the orange door)

I'll bring home some tracing paper today and sketch out where I think the control loops will go.

The cold caught up with the and I'm home sick today. No working today either. Though I had to play around for a couple of minutes with the sub-divisions:

When you subdivide it should also be possible to transfer UV mapping. Which would be another cool thing.

But I digress - need to get back to modelling this car.

TT I can't help noticing the sphere obeys quad based rules, how can I get my hands on that?

Break into my house, crack the password of my computer, search the HD for the source-code, copy, install. Easy peasy!
