Integrated BRL-CAD Modeling Environment

The Integrated BRL-CAD Modeling Environment (iBME, or spoken 'I-Beam') 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 iBME 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:

• iBME's core will be written in C/C++.
• OO Design will be leveraged to allow runtime-extensibility
• iBME 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
