Point Cloud Phase:
The optimized point cloud is transformed in a triangulated mesh, the available tools can enhance the mesh quality.
The mesh is dissected in several regions bounded by edges, each region can be fit to a NURBS surface. The mesh part recognized as an edge can be fit with loft and blend surfaces.
Edge recognition: automatic recognition of the model edges and fillet areas
Several strategies can be used inside Leios to rebuild the CAD model starting from the scanned dataset, the user can choose the more useful strategy for his needs and his field of work, such as: designing, freeform models, cultural heritage, and so on… Strategies can be combined to achieve the desired result.
Curves, Surfaces, Solids, Reference Geometry:
Creation, extraction and fitting of primitives.
Automatic and semi-automatic reconstruction of patches:
Automatic or manual reconstruction of the NURBS model with trimmed and analytic surfaces:
ANALYSIS AND INSPECTION:
RECONSTRUCTION BY FITTING:
SURFACING AND INSPECTION:
IMPORT/EXPORT FROM 3D SCANNERS:
– Leios imports ordered and non-ordered point clouds
– Point clouds in standard ASCII: asc, txt, dat, asd
– Closed formats: cwk, wd, opt, v3d, xyz
IMPORT/EXPORT TRIANGLE MESHES:
stl, vrml, obj, ply
IMPORT/EXPORT CAD DATA:

Leios can load and import about 70mln points with a 32bit Microsoft OSes and 2gb of RAM, more can be loaded with 32bit Microsoft OSes and 3,25gb of RAM (maximum addressable stack in 32bit Microsoft OSes).
With 64bit Microsoft OSes the point cloud size limit is bound to the RAM quantity available in the system (see SPECIFICATIONS)
Processor: Intel Core Duo T2300 or better, AMD Athlon XP X2 3800+ or better
Memory: 2GB in a 32bit SO. 4GB Recommended
Grapgic Card: NVidia Quadro / 6x or better, ATI/AMD FireGL/”X” or better
OS: Windows XP Professional SP2 or better, Windows Vista, Windows 7 (with more than 3GB RAM, a 64bit system is recommended)
To handle great amount of data, a Quad Core system with 8 GB RAM and Windows Vista / Windows 7 Professional / Windows 7 Ultimate is recommended.
