Freeform surface modelling is a technique for engineering Freeform Surfaces with a CAD or CAID system.
The technology has encompassed two main fields. Either creating aesthetic (class A surfaces) that also perform a function; for example, car bodies and consumer product outer forms, or technical surfaces for components such as gas turbine blades and other fluid dynamic engineering components.
CAD software packages use two basic methods for the creation of surfaces. The first begins with construction curves (splines) from which the 3D surface is then swept (section along guide rail) or meshed (lofted) through.
The second method is direct creation of the surface with manipulation of the surface poles/control points.
From these initially created surfaces, other surfaces are constructed using either derived methods such as offset or angled extensions from surfaces; or via bridging and blending between groups of surfaces.
Surfaces
Freeform surface, or freeform surfacing, is used in CAD and other computer graphics software to describe the skin of a 3D geometric element. Freeform surfaces do not have rigid radial dimensions, unlike regular surfaces such as planes, cylinders and conic surfaces. They are used to describe forms such as turbine blades, car bodies and boat hulls. Initially developed for the automotive and aerospace industries, freeform surfacing is now widely used in all engineering design disciplines from consumer goods products to ships. Most systems today use nonuniform rational B-spline (NURBS) mathematics to describe the surface forms; however, there are other methods such as Gorden surfaces or Coons surfaces .
Dune... Suggested Reading. Blasphemous 2 DeveloperInterview ... There is freeform climbing that lets you scale any surface you see, grappling hook-like tools that let you zip up and across large spaces, and the suspensor belt that lets you hover over gaps.
Total funding for the consortium amounts to €3.6m/£3m and will seek to advance the manufacture of nano-scale-accurate super-smooth optics with complex “freeform” surfaces for safe energy generation by laser-fusion.
... to happen, but thankfully the reports suggest that the headset wearer would use a flat surface like a desk or a table to draw with the Pencil, working with apps such as Freeform and Pixelmator.
Snufkin...Park officers! ... And once he got them all, there was a fabulous cut-scene that showed Snufkin trashing the park in general, wiping it off the surface of Mooninvalley, and returning the whole thing to a place of messy, freeform nature.

They demonstrated the use of calibrated freeform illuminators for Fourier ptychographic microscopy, 3D tomographic imaging and on-chip microscopy and used a calibrated freeform illuminator in an experiment to track bacterial growth.
Like before, this camera packs a freeform surface lens to minimize distortion, along with a relatively large f/2.2 aperture ... camera uses a Samsung JN1 sensor and, sadly, lacks a freeform lens.
13--there’s a whole new app called Freeform ... I found myself right at home, as I frequently play around Notes and find that Freeform does some of that general note-taking better, but it’s also a vastly more scalable surface.
Freeform surface elements may be an effective technique to achieve not just a large field of view but also a better and lighter image, but their weight and volume make them unwearable.
In order to push the performance of optical systems, aspheric- and freeform surfaces are used in state-of-the-art optic design for correcting aberrations ... The surface deviation can be calculated from the phase difference between the two wavefronts.
