obtain Nurbs from point clouds?
Hello,
I need to obtain nurbs surface from point clouds. or here there is a file called scattered point cloud it obtain urfaces, but i need export this surfaces as a CAD data, i need to convert it to igs format, for igs format i need obtain nurbs surfaces from point clouds, or is i possible to get igs format without obtaining nurbs from point clouds ? is it possible to covert matlab figure to igs format ?

iso2mesh: a 3D surface and volumetric mesh generator for matlab/octave
Filed under: Biotecnology, CAD, Computational Geometry, Graphics, Medicine

- iso2mesh is a matlab/octave-based meshing toolbox. It can create 3D tetrahedral finite element (FE) mesh from iso-surfaces and 3D binary volumetric images such as segmented MRI/CT scans.
- iso2mesh is an open-source software developed by [Qianqian Fang] at the [Photon Migration Lab], [Martinos Center for Biomedical Imaging], [Massachusetts General Hospital (Harvard Medical School)].
- A sibling project, metch – a mesh registration toolbox, is also hosted with this website.

Fast Surface Reconstruction: Delaunay2.5D
Filed under: Algorithms, Computational Geometry, Graphics
Can a surface reconstructor be faster than a 2D mesher?
It is coming soon the Delaunay2.5D algorithm a new fast surface reconstructor. It is currently in a prototype state, still have to code pre-processor and post-processor parts. I will include it in my thesis.
This algorithm can deal with millions of points in a matter of a few second, it is basically faster than a 2d delaunay triangulation. For this reason I am also thinking about extend it to 2D and 3D triangulations.
More infos about the algorithm performances and how does it work will be given in future. At the time I only have this video demostration and a demo version.I was impatient to publish something about it
.
Delaunay2_5D has been released here.
