Applying circular Curves to a 3d surface

Hello, can anyone help me. I am trying to apply a pattern to a surface. the surface itself is a quarter of an ellipsoid (I have redrawn this independently, not created from splitting an ellipsoid). as the surface can not be unrolled as it curves in 2 directions I had to redraw the area in 2 dimensions so I can position the pattern. My aim was to use the apply UV curves tool, however, when I do this I get considerable distortion as I move out from the centre. please see below images



any help would be greatly appreciated.

thanks

James

Hi James,

there are various ways to achieve this. Two easy ways with medium precision:

  1. _Squish the compound ellipsoid to a planar surface. Array your curves and _SquishBack onto the ellipsoid.
  2. _UnrollSrfUV the compound ellipsoid, Array the curves (or Spheres) and use _FlowAlongSrf (for Spheres with the Rigid Option) to transfer from 2D to 3D (_intersect the spheres and ellipsoid).

Best,
Jess

Edit: if the circles needs to be more precise regarding diameter then use cylinders instead of spheres

Hello Jess

fantastic, the squish method worked fine, thank you very much.
