so whats the problem with using texture()? http://processing.org/reference/texture_.html
Sure you can create basic shapes, especially rects between beginShape, endShape.

Did you remove the original question  Not very helpful if you actually want people to give you an answer...

For what it's worth I'm not convinced you can use basic shapes with texture.  Texture only works with the 3D renderer and from what I can tell the basic shapes are 2D only, which seems like an inherent incompatibility.

Depending on your use-case you might take the sprite approach.  Otherwise you'll probably have to get to grips with drawing in code...

I did delete the post by mistake, sorry.
I'm coming to grips with this problem. I may try to use a bezier circle approach, but overall the problem of ellipses/circles and textures seems a bit silly to a newcomer.

Hmm...  I guess it depends on your experience in other languages.  I'm pretty sure texture-mapping is a rather non-trivial problem and a lot goes on under-the-hood to map a texture onto a shape (bearing in mind you're also able to set UV mapping coordinates).

Another possible alternative might be to use the shape as an alpha mask; though that may not be any simpler as I think you'd need to convert the shape to a PImage...

TBH you're almost certainly have to use vertices/curves at some point so it's worth taking that route.

Well, it sure isn't implemented in JAVA2D, P2D might support it but only for polygons (if I haven't read code too fast) and I suppose it is fully supported only on 3D indeed.

For any arbitrary shape in 2D, including text, you can use the method I show in Re: fill shape with pattern.
