UGC API V2 User's Manual

2.0.3

UGC API V2 is an application programmers interface for developers of 3-D software applications that utilize unstructured meshing technology. API V2's architecture consists of a database and a meshing library. The database library owns all mesh data and contains API functions for the transfer of data between the mesh library and the application. It also contains functions for dynamic loading of meshing libraries, allowing applications to access multiple meshing libraries simultaneously. The more compact meshing library API contains functions to extract the particulars of the library, including run-time parameters, allowable mesh types and available algorithms. Algorithm types are non-specific and may pertain to peripheral mesh operations as well as generation techniques. An example implementation of a database library is included for distribution. Its use markedly reduces the effort required to develop compliant applications or meshing libraries. An example Fortran wrapper library is also provided to allow Fortran applications to access compliant libraries. API V2's future viability as a standard for unstructured meshing is dependent on the ability to maintain and extend the API, to provide training and to define certification criteria.
