Flow

Hi, I´m working with streamingLines 3d [ flow ] to build geometries. What i´m doing is finding the closest point between sphere mesh and points on streaminlines 3d to rebuild a new mesh. However i´m far away from the result that i´m looking for. in the image of the right i show the kind o result that i want. Maybe this kind of approach is not the best way anyone know some approach to get this kind of result ?! Thanks in Advance.
