VDAFS - Vereinung Deutsche Automobilindustrie Flächen Schnittstelle

German neutral file format for the exchange of surface geometry which was developed to exchange free form surfaces. VDAFS supports elementary curve and surface geometry entities and some topology to define more complex models. VDAFS is used by the German automotive industry to define surface models such as car bodies.

Allows reading and writing of VDAFS files to/from simple C++ data structures which leverage the Nlib library to represent all the geometry data in the VDAFS file.

• Major Features:
• Resistant to faults in the physical format of the VDAFS file.
• Reads all VDAFS geometry entities.
• Imports and exports points, curves, surfaces, and trimmed surfaces. TOP shells are read as independent faces only. BReps can be output as TOPs.

This combines VDAFS/NLib with a sophisticated tool for creating proper trimmed surfaces from flawed real world data.

• Major Features:
• Everything listed above under VDAFS/Nlib.
• Sophisticated cleaning tools: eliminating minor self-intersections and gaps, improving singularities, etc.
• Supports conversions of IwBrep entities to and from VDAFS FACEs and TOPs.

SMLib is built around a core of NLib and TSNLib. Thus VDAFS/TSNLib works perfectly with SMLib. VDAFS/SMLib requires SMLib. All the needed NLib and TSNLib functions are included there, making the logistics much easier for all of us.
