The PVM patch for POV-Ray gives POV the ability to distribute a rendering across multiple heterogeneous systems. Using the PVM code, there is one master and many slave tasks. The master has the responsibility of dividing the image up into small blocks, which are assigned to the slaves. When the slaves have finished rendering the blocks, they are sent back to the master, which combines them to form the final image.
The Interreality project is a collection of Open Source, Free Software projects based on the Virtual Object System (VOS) platform. The goal is to develop a free and open platform for multi-user 3D virtual reality games, applications, and interactive, collaborative 3D virtual spaces. VOS is a powerful and generic network object framework designed to support a variety of high-performance applications. It is the basis for Ter'Angreal, a general-purpose browser application for entering and participating in 3D worlds.
Gmandel is a program for exploring intricate and beautiful details of the Mandelbrot set, the classic fractal image. It displays images and allows you to select portions, and click-and- drag for enhancement. You can set the number of colors per iteration, and the iteration limit. It is multi-threaded and runs especially well on SMP machines, and can use the combined processing power in a computer cluster.
Gled is a C++ framework for rapid development of applications requiring a GUI, 3D graphics, or support for distributed computing. It extends the ROOT framework (a standard data-analysis tool in high-energy physics) with mechanisms for object collection management and serialization, multi-threaded execution, GUI auto-generation (object browser and editor), and dynamic visualization (OpenGL). The distributed computing model of Gled is a hierarchical tree of nodes connected via TCP/IP sockets. Gled provides authentication and access control, data exchange, proxying of object collections, and remote method-call propagation and execution. It can be dynamically extended with library sets. Their creation is facilitated by a set of scripts for creation of user-code stubs. Simple tasks and application configuration can be done efficiently via the interactive C++ interpreter (CINT). Gled is used for development of programs in high energy physics and as a research tool in distributed and grid computing.
Drqueue is a distributed rendering queue. It helps manage jobs on a render farm. It works under Linux, Mac OS X, FreeBSD, IRIX, and Windows, supports Maya, Blender, Lightwave, Mental Ray, Bmrt (Renderman), 3Delight, and Pixie out of the box, and can support any other renderer or computing task that can be handled via scripting.
JCGrid is a set of easy-to-use tools for real-world grid-computing. It doesn't require any file system sharing capability (such as NFS). It allows you to easily split a CPU-intensive task among several computers by using the JCGrid framework. Any file required for completing the task will be transferred by the framework. A cache is used in order to minimize file transfers. You can easily add or remove computers from the grid at runtime without losing any work. Support for POVRay is included as an example of use.
Equalizer is middleware for creating and deploying parallel OpenGL-based applications. It enables applications to benefit from multiple graphics cards, processors, and computers to scale rendering performance, visual quality, and display size. An Equalizer-based application runs unmodified on any visualization system, from a simple workstation to large scale graphics clusters, multi-GPU workstations, and Virtual Reality installations.
