GS Dev Requirements

Geometry Service Requirements

• Geometry versioning: revision history of geometry changes such as who did what to the model and for which analysis, when changes were made, by whom, etc.
• Direct association of stored geometry with external data
• Multi-user access controls that allow multiple people to work on the same models at the same time
• Programmable access-controlled interface that utilizes reuseable code for consistent end-to-end access to geometric data.
• Dynamic geometry
• Geometry articulation and editing constraints
• Unified repository of geometry in one storage location.
• Reuse of identical geometry parts (single instancing).
• Improved/advanced collaboration.

Identified Executables

• Thin Client
  • Any Language
  • Provides:
    • Communicates with Geometry Engine via GS Protocol
    • Gui Interface
  • GS Dev Thin Client Requirements

• Geometry Engine
  • C++
  • Provides:
    • Geometry Management (via SVN)
    • Geometry Conversion, Import, Export
    • RayTracing
    • Communications with external Geometry Engines
    • Communications with external Geometry Repositories
    • Communications with any other application that implements the GS Protocol
  • GS Dev Geometry Engine Requirements

Visual Conception

A Thin Client connected to a Geometry Service, all running on one physical machine

Thin Clients connected to Geometry Services, each running on independent physical machines, but connected to a 'headless' Geometry Service. The 'headless' geometry service also serves other enterprise level applications.
