[Tutorial > Modeling] A PoorFlatEllipsoidIndian Bowl

simon le bon

Is it a Pottery Challenge or What?

Here is another fantastic way i was totaly ignorant to model our Bowl. Thanks Pilou to link this to us!

Pilou's link linking to:

which linking to:
KitoRaupp Pottery Twist on Youtube
and
KitoRaupp Spirale Tutorial on Youtube
and others KitoRaupp productions

On another hand the technic used is not so easy to reproduce. So I made this small video to clarify it. (I'm the author of nothing here). Simon

These gif animations are very cool, Simon! Why don't you include the full size image with the [img] tags instead - after all they are not too big?

simon le bon

Hi! dear Gaieus, our cool "watching and listening man" (I guess at night you like listen the stars in the sky !!)

In facts I have made this Gif (450x337) to fit the forum. It is an experiment to deliver an animated explanation which needs just few seconds, for it is the case very often. I've first tried to display it in full format, afterwords I thought an animated thumbnail leading to the full format was better. I don't know. It depends of the case for sure

PS: i remember now why i made this way! This Gif is 732Ko . So if we put several in the same page we are surely going to difficult loading..

Merci Jean-Franco
Gaieus, "../but I do like them for sure.
There is many advantages to use Viddler: great picture quality, easy upload, nice statistics, Flash or original downloads, video comments, good sharing options,... Nothing is perfect, the streaming is a bit erratic So I now put direct link systematically just below .

I have made a mistake at the end of my previous second video, PaintingTheBowl_B.
In order to reconstruct my Bowl, I have copied the single slice x49 (Cause my starting stripped tube was based on a 50 segments circle) (i had been surprise by the enormous time this operation had taken )
In fact i had forgotten this supposed "single slice" was already made with a couple of slices (mirrored). So, it was only necessary to copy it by 24 !!

%(#800000)[This thread is still intend to beginners. Regular SketchUp users might waste their time on this space (but who knows ]
.
Secondly i have missed to explore a modeling way which makes school inside SU. It is certainly not the easiest way nor time saving one. But it is a fresh handmade way.

Due to the intensive manipulations, we are driven to make a lot of small mistakes. Most of them they come from Move tool. This is problematic when we want to paint and modify the object.

Here is cases of twisted rings.

So here is a second method, yes less fun but more robust:

Monday, March 2nd.
After months I come back on this thread.

First, it's because the illuminating and simple Voder Vocoder's solution isn't available anymore on DataFileHost.

Secondly because since the end of this first part thread, fantastic tools had been developped by some (wellknown) especially tallented Ruby Makers. An important part of those tools leads to allow SketchUp to be a modelling engine.

so Here is my PoorFlatEllipsoidIndian Bowl made with: SubdivideAndSmooth v.1.00 _ by Dale Martens (Whaat)
(I must say i'm not at all specialized with S&S. It is not an easy set of tools. I must confess that when after a while, i want use it again, i must go back to see the video tuts 1 & 2 again and again . But, but, little a little i find solutions to obtain what i want!! )(So for asking help, you can face up to our great masters as: Solo, Teezer, Boofredlay, Kwistenbiebel, Mariocha,.. sorry for those I forget or ignore)

Snippet pasted from Shaping a cylinder - interesting technique about the "fifteen degrees rotation" needed to achieve the spiral.

personal asking:
Why only a 15° disc rotation allows copy of ring angled edges to fit with the source, whatever the height is?

.

Ecuadorian answer:
360º (full circle) / 24 sides in circle (SketchUp default) = 15º

If you want to use a 10º degree rotation you need to start with 36 sides in the circle.

If you want to do it with 20º, you need an 18-sided circle.

Solution during the night:
I was thinking of this in the very morning before wake! And i've find this is not something of "big theory" as I thought, but something pretty simple

simon

simon le bon

And if you need a spiral line angled as you whish: "No Problem "

it's always me

simon le bon

Come on Guys,
No good Tip added, no alternative process suggested, no remark on where I'm wrong, no companions to follow me in this "tutorials trail". Do you think I'm making this heavy work for some individual glory? I make it for you, dear-to-my-heart community. To accomplish something in a participative way.. I'm tired to work on the wind.

simon.

Simon

What can I say? I liked your tutorial, I like the way you use SDS. I would have used the follow me tool or created a proxy actually but seeing your process you seem to have more control over the final outcome giving your method more accuracy.
That's the great thing about SU, there are so many solutions to a problem, and finding the one that works easiest to you is the answer.

Believe it or not I learn everyday on this forum about new techniques, faster work arounds, hell just keeping up with all the new plugins is already becoming a fulltime job....and I'm loving it.
I forsee we will have a bunch of new tools soon as with the advent of one cool plugin it normally inspires or even opens the door to another, I bet in a year from now creating the same bowl/vase will be even easier with a tool we have not seen yet.

simon le bon

Thanks Solo for this friendly post which freeing my mind.

I think my set of simple indian bowls is a good exercise to introduce new modelling plugins and to show what they potentially are able to do.

nomeradona

thanks i love your approach.

simon le bon

thanks to you nomeradona for this fresh word

I have tried to find out how to paint this S&S Bowl. (lot of tries believe me). It is not simple because S&S shapes are based on square, not on circle. And if we don't want to paint by hand the overall indian pot, we have to use the sectors solution (see VoderVocoder solution). In our case, the minimum sector is a quarter.

Here is the first pair of solutions. One solution to isolate the quarter,+ one to paint the bowl.
(tomorrow (i hope) the second pair )

Comment1:
I have tried boolean tools to isolate the quarter bowl from the crossed panel: Boolean--OSCoolean , BoolTools just released without success. the shape seems to be not a "valid solid"

comment2:
Rotate and copy the quarter needs great accuracy: i have missed it for a while

plugins used:
Construction Line Tool by Jim
Projection toolbar by Didier Bur

simon, still walking on this tutorials trek

Gaieus

Simon, have you also tried UVTools? These radial shapes seem to be perfect candidates for it.

For the BoolTools, you'd probably have to "close" the empty sides of the quarter shapes.

simon le bon

Hi Gaieus
Using UVTools to "paint" my Bowl, is I think an excellent idea. I have totaly forget it, but also have never use it. So i keep it in mind and will try something later.

@unknownuser said:

I had already tried this but it seems it is the Bowl itself which need to be closed. And I have to find how i can do it, and undo !

( Subdivide & Smooth , BoolTools, UVTools, Whaat's shadow is all over this thread )

simon le bon

Alternate solutions:
One to isolate the quarter, and two to paint the bowl.

I'm a bit satisfied (by myself ) to have found this lighter second solution to isolate the quarter. Because Section Plane Tool is rarely used and often forgotten
Thank you
