[Tutorial > Modeling] A PoorFlatEllipsoidIndian Bowl
-
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) = 15ºIf 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

And if you need a spiral line angled as you whish: "No Problem
"
it's always me

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.

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. -
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.

thanks i love your approach.

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 Bursimon, still walking on this tutorials trek
-
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.
-
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:
For the BoolTools, you'd probably have to "close" the empty sides of the quarter shapes.
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
) -
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
for your too much good SectionCutFace v2.0
The other way to paint the Bowl is not really new, but it's pleasant to show how we can play with Components.
Thank you
for your too much good Mirror_31.rb
If you desire to play with it: PotterSC_S&S_SCF.skp

Happy birthday Simon, you do realise you ar now officially over half a century old right?
Have a great day and try not draw to much attention to the fact...too late.

"Fire-Water Pot"
This time my purpose is to play With Chris Fullmer plugin: ShapeBender Beta V0.51.
My efforts point to use it as an accurate and predictable tool.
And my exercise is the following: Wrap a thick label on a Rum Pot. (The indians Fire-Water).These pictures explain surely better than i can say what i want to obtain:

"Fire-Water Pot":Preamble and Precautions
Due to one current limitation of ShapeBender ( that we gladly hope it will be fixed in a next update
) concerning external elements treatment during the Bend process, we should provide a larger label and anticipate to remove them.@chris fullmer said:
Jeff, I want to emphasize a bug in the code since it might matter to you, since you are making shapes that get built. But the first and last angles might not be calculated the way you would expect - I suppose that depends on what you expect. The image shows the problem. Every sliced part of the model lines up correctly to the curve expect the two ends. That is because I am not actually finding that outer angle at this point. It is a planned improvement
So I thought you should be aware of that so that it doesn't cause you undue pain when you can't figure out why stuff is not lining up right,
Chris
For a study upon what interess our purpose about this specific limitation, please threw an eye on this Wrap Test Slideshow
or the WrapTest Album
Some Precautions using ShapeBender: in order to avoid some odd behaviors which possibly might happen...
1_ Draw curves or Bezier curves from left to right along red axis.
2_ Avoid as possible to explode curves and/or Weld them.
3_ Draw basic circles and circles to be used with FollowMe Tool on three sides multiples: 24; 36; 48; etc...
4_ Draw circles carefully, stretching them along a primary axis
Plugins used in the following work:
Construction Line Tool
Point v1.2
Selection Toys (1.9.0)
BezierSpline v1.21
Soften/Unsoften
Joint Push Pull - Visual Edition
MakeFaces v.1.400**/*

These are great updates, Simon, thanks for making them!

To draw your first pot of Rhum, you first drink a large glass
And you surely know you can do better!! So you thake~ another laârge glass of Rhum and you work again:
Blut yu know it can be bbe better, and a little dring to get curage
I, I du nut remember WHen!! i discovered "H" is missing to RUM in English: perhaps when i was beginning to drink th th''ird or else glass...
Well hiere is the niflal tutorial..;...Hips!!
Sorry, excuse ma a second....

"Fire-Water Pot": Picture by Picture tutorial:
Step 1: Determination of our basic elements: pot's shape, rectangle and cartridge for the label.
-Our Workflow
- Basic label's rectangle determination. Based on straight lines needed by ShapeBender as they correspond to the curves. A larger width is planned with the 90° round curve.
- Cartridge can be determinated at this stage.
This is the less precise part of the work. Alas, as far, nothing in ShapeBender processes authorizes a total predictable management for the cartridge size, at issue of the second bending.
- Cartridge completion: no tut for this. Using PushPull, 3DTxt, etc..You Know that. :lol:
(I will make something in a next post on how smooth everything as if the letters were cast in glass. But i will ask for the community to help because i havn't found everything)

"Fire-Water Pot": Picture by Picture tutorial:
Step 3: Finalization of second bended shapes.
- everything is in the picture and the video.
>trick one: use Face Style Toolbar's transparency to select only the edges we want.
>trick two: close the sides with Todd Burch's MakeFaces after deleting the unwanted endings and before delete the unwanted inside face (which have served to close the sides)
- Establish the inside volume we need to pierce the pot.
1 Using Fredo6's Joint Push Pull helps keep and preserve lines that interess us.
2 To have the overall geometry unhide leads to a good work for JointPushPull.
**/*
*/
Step 4: Piercing the pot.
-Position the brother shape.
With unhide shape, hidden geometry displayed and build in construction lines well rotated, it is very easy to achieve a perfect position. I have used the middle point (which is a junction point) of the upper inside arc of a circle 
-Intersect with model
Explode everything, intersect.
- Remove unwanted

*s - everything is in the picture and the video.

That's great, thank you so much for putting that together Simon! That shows well what shapebender was made to do. Granted, there is still room for improvement on that script, particularly with how the end segments do not bend like the rest, but you show how to work around that very well. Thanks!
Chris
