Can this be done in SU?

jeff hammond

There's only one decent way to model such things and it's not supported in SU.

why not nurbs?

[edit]

here's another approach for keeping it in sketchup.. using the loft tool in curviloft.

Jeff,

Nice to see videos on curviloft, there'll probably never be enough for me.
Now, how to resolve the dent these intersections put into the surface?

Yes, thanks, Jeff.

I think you should drop a copy of you vid over in the one or all of the curvi threads.

Probably not exactly what you need, but still this is an interesting Kito Raupp's approach (especially the last example). All SU native tools.

Here's a similar way...

...or with Artisan...

hey peter..

i really don't know what the actual cause is behind shading errors.. i do know that sketchup doesn't like a bunch of vertices defining the boundaries of a facet which is part of a curved surface (which is likely to occur when you intersect two curved surfaces)..

this .3ds import triangulates everything and the resulting sketchup model doesn't exhibit the shading error.

SU obj exporter as well. A render engine will do the same when rendering. Kerky and Thea have solved the smoothing normals problem (it's called "termination problem"), other physically correct apps like octane, Kray, Cycles etc have not. So, wait for ugly artifacts, under certain circumstances of lighting.
What about using subdivisions/real displacements on such meshes? For exactly the same reason, what about importing such topology in zbrush, MudBox, sculptris, blender? The only solution will come via retopology methods. Quite not practical.

Anyway, there're some decent ways to model such things, non of them is supported in SU (IMO, it never will). SU user interface is against these principles of box modeling.

Well, that's still very helpful on curvi use. I finally figured out, since no one would tell me, that one must 'escape' from orbiting while in edit mode in order to preserve the session. 'Space' ends the session without saving.

This pic has nothing to do with that. Yes, for this case CurviLoft seems fast and well suited.

yeah.. i think it's the best way to do this if the final shape is what i'm imagining Twan is looking for.

lol. nice.

what's all the fuss? Of course SU can handle it!

Very nice suggestions, leading to terrible topology.
Don't try it if some real displacement gonna happen.
For exactly the same reason don't import it in zbrush or sculptris.

why not?

You need some more tools now, like loop cuts etc.
You don't also have a UI for making this work fast and easy.
You also need artisan to make it smooth.

ok, if we are talking about create and animate organic characters and so on, i totally agree with you.. blender is blender..
but if we are just talking of a coffee cup i think sketchup is good enough, you are right, maybe you need a couple of plugins of course, but at least you don't need to import/export/convert/learn blender..
