Geometry Service Project Main

This page contains the design document for an enhancement or feature. The design should be considered a work in progress and may not represent the final design. As this is a collaborative design, contributions and participation from other developers and users is encouraged. Use the discussion page for providing comments and suggestions.

The Geometry Service Project (GS) is the internal name for a project under development that aims to restructure the geometry management services within BRL-CAD and provide a new user interface. More specifically, the restructuring aims to leverage an object-oriented design and encapsulate much of the existing functionality in BRL-CAD through three specifically layered interfaces. The GS Project consists of three major pieces:

• Geometry Engine - C++ library consisting of the existing BRL-CAD libraries and added functionality such as integration of all BRL-CAD file format converters and SVN storage utilities.
• Geometry Service - Background service that leverages a Geometry Engine, a Session Manager, an Access Manager, and a Communications Manager to facilitate multi-user, multi-threaded, networked access to the Geometry Engine.
• GUI - Standalone 'thin client' that provides visualization and captures user input. This thin Client is connected a Geometry Service via one of many communication mediums with network sockets being the most prevalent.

Project implementation particulars:

• GS's core will be written in C/C++.
• OO Design will be leveraged to allow runtime-extensibility
• GS leverages existing functionality in BRL-CAD's libraries and binaries
• The Geometry Engine provides compile-time bindings
• The Geometry Service provides a network protocol run-time interface
• Each of the three major pieces will be stand-alone products
