CAVERNsoft G2 is an Open Source C++ ready2ware toolkit for building collaborative networked applications. CAVERNsoft's main strength is in providing networking capabilities for supporting high throughput collaborative applications. These applications need not be CAVE applications. In addition CAVERNsoft provides modules for accelerating the construction of Tele-Immersion (or collaborative virtual reality) applications.

The following is a list of CAVERNsoft G2's capabilities. More information can be found in the documentation section.

Low/Mid-level networking classes

These capabilities work across SGI, Linux, Solaris and Win32 (Windows 9x, NT, 2000) platforms.

  • TCP, UDP, multicast, HTTP classes.
  • UDP reflector and multicast bridge class.
  • TCP reflector.
  • Remote procedure call classes.
  • 32 and 64 bit remote file I/O classes.
  • Client/Server database classes.
  • Parallel socket TCP classes.
  • Parallel socket 32 and 64 bit remote file I/O classes.
  • 32 and 64 bit remote file I/O classes using parallel sockets
  • Cross-platform data conversions.
  • Mutual exclusion and threading classes.
  • Network performance monitoring abilities
Higher level modules

These modules are designed mainly for SGI computers. They use the CAVE library and Iris Performer.

  • Audio streaming.
  • Basic avatar classes without graphics.
  • Performer articulated avatars.
  • Performer navigation and collision detection.
  • Performer menus.
  • Performer Pick and Move
  • Performer NetDCS
  • Collaborative widget interface.
  • Collaborative framework for animating data sets.
  • LIMBO- basic collaborative framework for building other collaborative applications.
  • Manipulative coordinate system class for programming transformations.

A multidisciplinary, finite element–based, graphics-oriented, linear and nonlinear analysis capability that includes such disciplines as structures, heat transfer, linear aerodynamics, computational fluid dynamics, acoustics, propulsion and controls engineering, has been achieved by integrating several new modules in the original STARS (STructural Analysis RoutineS) computer program. Each individual analysis module is general-purpose in nature and is effectively integrated to yield aeroelastic and aeroservoelastic solution of complex engineering problems. Examples of advanced NASA Dryden Flight Research Center projects analyzed by the code in recent years include the X-29A, F-18 High Alpha Research Vehicle, and Hyper-X/X-43 projects. Extensive graphics capabilities exist for convenient model development and postprocessing of analysis results. The program is written in modular form in standard FORTRAN language to run on a variety of computers, such as the IBM RISC/6000, SGI, DEC, Cray, and PC; associated graphics codes use OpenGL and IBM/graPHIGS language for color depiction. Out-of-core and parallel processing of solutions are available.

Adoption of special sparse matrix storage schemes and a multi frontal approach for a sparse matrix decomposition, as well as a multitude of new finite elements, renders the program economical and efficient. Also, an optimizer module has been added to the program, which enables effective design of structural systems. Further, a GUI module has been added to render additional guidance for efficient running of the code.

A simulation of the Euler/Navier Stokes CFD-based unsteady flow enables efficient and accurate solution of the aeroelastic, aeroservoelastic, aero-acoustics, and aerothermo-servo-elastic-acoustic problems.
