Detailed Description

Free Form Deformation of a 3D surface and point clouds, with structured lattice.

Free Form deformation tool for 3D geometries (surface and point clouds). Basically, it builds an elemental 3D shape (box, wedge, sphere or cylinder ) around the geometry and set a structured cartesian mesh of control points on it (lattice). Displacements of each control point are linked to the geometry inside the shape by means of a NURBS volumetric parameterization. Deformation will be applied only to those portion of geometry encased into the 3D shape.

Set if displacements are meant as global-true or local-false. Global means that displacements are defined in world xyz coordinate. Local means that displacements are defined in local reference frame of the lattice, accounting of:

lattice rigid roto-translation due to changing in Origin/RefSystem.
lattice system coordinates transformation.

◆ setLattice() [1/4]

void mimmo::FFDLattice::setLattice	(	BasicShape *	shape,
