Hello,

I haven't posted here for a while. I've just "finished" a first attempt
at curving patterns. Here's what it looks like on a plane, a cylinder
and a sphere for the T-pattern.

I'm also wondering if i shouldn't find a slightly more homogeneous
paving on the sphere. The pattern seems far too distorted in latitude.

I cheated a bit with the sphere because I don't know (yet) how to treat
the poles.


Your feedback is welcome.

That looks very nice.

Hi, kurtz !

As for me, it looks attractive and accurate enough. Don't you think that
the reason is a perspective distortion of camera ?

Are these just CSG objects with your own texture mapping using tiling 
patterns, or are you using isosurfaces with the tiles defining the surface?

They are pretty cool looking already.  I'd like to see how you do it, as 
I'm constantly looking for interesting surface texture perturbations to 
steal (I mean borrow) :-)

No texture mapping, no isosurface, "just" CGS with spheres, cylinders,
torus and planes.

Still a few things to fine-tune. Then I'll make a new page on my site to
explain how it's all built.




Thanks to everyone for your comments.

I like the results a lot, and I'm also curious to see your page with the 
explanations.
