Pole-less Sphere? Cylinder to Sphere?

vvvv beta question
#1

Hey,

Really enjoying vvvv, but I can’t seem to figure out how to get a pole-less sphere, or transform a cylinder to a sphere, so that the vertices are the same in number with respect to a sphere and cylinder primitive (see attached). A simple thing I am missing, or do I have to take apart the spread and piece by piece construct this?

Thanks,

hi xirja, you can try to use SphericalSpread and ConvexHull to build a sphere with evenly spaced vertex distribution.

or do this in a 3D program like cinema4d and export to xfile

Hi ton, u7,

Spherical spread in the new version is really nice, for as you say evenly distributed points, however I’m looking for a duplication of the symmetry in the sphere (primitive) arrangement. I’ve been able to hack together something really close using an altered method of fibo’s (see attached), but can’t figure out how to transform the Y vector to get perfect alignment? Any guidance (feeling like a bit of a tard in my late 30’s :( ) ?

Thanks,

quick’n’dirty

substitute the cylinder’s Y-values with a similar sphere’s Y-values…

Many thanks kalle, nothing dirty about that! Sweet, now to replace the sphere in fibo’s coordinate transform with this one to get seamless ends, w’oh yeah!
