Texturing a sphere
-
Hello,
first of all, I'm using sketchup since 1,5 years and I'm thinking, it's a great 3D-editing-app.
I only have one problem. In sketchup it is possible to put textures or images as textures on curved-based meshes or faces. Then the texture will be repeat on x/y axes. How can I deactivate this automatic repeat? In a simple test (please have a look at the attachment) I setup a scene with a uvsphere. On the sphere my texture shouldn't repeat. How can I change this?
Cheers

Hi Monk,
Use Whaat's "UV Tools" plugin for spherical and cylindrical projections.

Thanks a lot. It works perfectly.

edit:
How can I create a sphere, which I can transform after creation? So far I use the "normal way" to create a sphere:
Drawing a circle (horizontal), then drawing another circle (vertical), selecting the horizontal and then follow the vertical. After this I get in wireframe-mode only to circles and I can't edit my sphere.

You start with high poly circles. You cannot edit the circle entity after using the follow me tool on it as it will explode the circle.
To draw a circle with your custom segment number, start drawing it, type the number followed by an S (like 96s) and hit enter. From now on, in your model, during that session, all new circles will have this segment count until you change it again so you don1t even need to do it for the vertical circle (for the sphere).

You are really fast.
I know this technique, but in google warehouse I found spheres with faces, which are fully editable. This spheres you could transform. My sphere cannot be transformed. I want to draw a ballon. The problem with the warehouse-spheres is, that the number of the segments is very low.
Your world sphere in google warehouse must have faces, because you must selected the faces for your textures. How do you do that? How do you create this sphere?

I made it in the exact same way you do it (as you wrote).
Then just imported a texture, applied it on a facet (ah, maybe this is what you mean; you can unhide hidden geometry by clicking on View > Hidden geometry), sampled that material, applied it on the whole sphere and then ran the script.

Gaieus, this was exactly what I mean. Thank you very very much. Now I can edit my sphere. Big thanks to you.

Cool, glad it helped.
And cool balloon, too, in your avatar!

Thanks. I will show you here in this thread my ballon-pic.

hi, i have recently begun using sketchup and was wondering if it was possible to cover multiple spherical surfaces simultaneously through some sort of shortcut or must they all be done individually.
-
I think, Whaat's plugin works on an individual basis (i.e. after you apply the texture on one sphere, you need to do the spherical mapping each by each).
But why don't you give it a try?
