Projecting and conforming an object to mesh, quick mesh warp in Houdini

Projecting and conforming an object to mesh, quick mesh warp

this workflow projects a grid onto a tube, then uses this deformation to warp another object add tube node orientation: x axis add grid node orientation: YZ plane add ray node (feed grid into 1st input, tube into 2nd) direction type: bidirectional add torus node add lattice deform node (feed torus into 1st, grid into 2nd, ray into 3rd input) click points tab

or

use surface deform node (feed torus into 1st, grid into 2nd, ray into 3rd input) this deforms and distorts much more

or

use point deform node, deformation matrix see src
