Reverse modelling

Is it possible to carry out reverse modeling of a point cloud or a mesh and could someone please guide me how.

Many thanks

Hello Mrinny,

The standard Open Source distribution of Open CASCADE Technology (OCCT) provides a set of tools for surface reconstruction (packages Plate, GeomPlate). These tools may be used to approximate the input cloud of points (that may be triangulation nodes) with a NURBS surface. To test the GeomPlate functionality you may check Draw commands "plate", "gplate", "approxplate" implemented in the file BRepTest_FillingCommands.cxx.

In addition to the standard Plate functionality we offer an advanced software product called "Surface from Scattered Points" that allows to receive better results of approximation due to usage of different approach to approximation giving less oscillations. You may find more information about this component at http://www.opencascade.org/support/products/ssp/.
