Lofter 3D Technology

The Lofter (*) system is a modeler of 3D surfaces, defined by interactive programming.

Originally developed for marine applications (hulls and aerodynamic appendages), Lofter finds his natural extension in a broad range of applications, where shape continuity and surface smoothness are strongly required.

Precise and flexible 3D modelling.

Full 3D "No fairing" programmable Technology.

Lofter produces, smooth 3D mathematical surfaces that do not need to be faired in post-production. Ready for CNC machining.

"No formulas, no written instructions". The shape of the objects is carefully "programmed" by graphically defined functions (X, Y, Z), using an extensive library of primitives, which includes a variety of splines and other intelligent means of computational geometry. The modeling process is friendly: fast and intuitive.

“You say what you want to do and Lofter simply does it, ....with mathematical precision”

Full Design control. A suite of interactive tools and smart algorithms allows controlling the surface shape and its curvatures during the design session.

Full Targets control. At each step the dimensional and dimensionless Design parameters are recalculated and available on line.

Innovative proprietary CAD kernel.

On the basis of cross sections, boundary profiles and shape control functions, the Lofter algorithms describe a 3D surface with slope and curvature continuity., Learn more….

Lofter does not render, but outputs wireframes with a lattice of Control points coordinates for renderers.

This highly efficient and easy 3D CAD engine can be used as a stand-alone modeler or as a pre-processor, to compute dense grids of control points for third-party rendering, post-processing or CAE codes.

Open System to third party Systems.

Exporting Lofter surfaces to other 3D modelers that accept 3D grids of control points as input is immediate.

Dedicated Rhinoscript commands are provided for quick export of Lofter grids to Rhinoceros (*).

Spreadsheet technology also makes it easy to customize Excel sheets to output offsets in tabular form, for shipyard needs.
