Modify rectangular png file into a circle

png
circle

#1

I have a long png file, think of it as a ribbon.
I want to be able to form a circle with that ribbon and export it for further applications.
Being a novice, words of one syllable appreciated if you have a solution for me.


#2

It would be easier if you could share the png so we can see just what you have to work with.

(Sorry. I tried to keep it to single syllable words. ) :smiley:

Most likely the answer will be to import the image as a material/texture and apply it to a cylinder.


#3

I think you meant ‘share’!
‘Shape’ is what I need to do!


I hope you can see the gist of it
This image is a logo deconstructed and then reconstructed into ‘fabric’

Thank you for your assistance


#4

So you want this pattern on the outside of a short cylinder, right?


#5

Think of it more as a watch bezel
There will be stretching issues on the outside and creasing on the inside
So, I need to be able to modify the ‘ribbon’ width to make it look good
Hope that makes sense


#6

OK. I understand. To apply the texture that way, you would need to make a ring shape in Photoshop or something. SketchUp isn’t designed to bend images like that.

It may help you by showing my start point


#8

Ok, thank you very much for your help
It is very much appreciated
Without photoshop, do you know how I could create such an effect?


#9

I suppose with that basic image unit, you could use it it to paint small face arranged in a ring.


#10

What I was thinking - thanks again


#11

I’m sure this isn’t exactly right but it shows the idea. You can see the single element inside the circle. I made it a component so I could tweak the texture after getting it copied around the ring. Save a ton of work for edits.


#12

So sorry, I had to run out and rather assumed that my advice was complete
I cannot tell you how impressed I am
Much appreciated


#13

No problem at all.

:+1:


#14

So, the methodology you used is to use the red axis. effectively the radius of the inner and outer circles to distribute the component at equal intermittent points - so, say 36 components, one every 10 degrees.
Is that right?


#15

Yes, that’s right. And because I was lazy, I started by drawing a 36-sided circle centered on the origin and then I used Offset to make an inner circle. I drew lines between corresponding vertices to separate a single sector and erased the rest of the two circles. After painting importing the image and apply it as a material on the face, I made the trapezoid a component and copied it with the radial array function of the Rotate tool. I hid the edges between sectors so the ring looks like one piece.

Thanks again!
I run some social media stuff on a fairly new platform - steemit - this is their logo which I have reworked
If you would be interested as a software supplier to get involved in judging competitions, let me know.
Might be a bit of fun for the brand and the team!


#17

Thanks. I’m not a software supplier, though. I’m just a satisfied user of SketchUp.
