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.
trend is a general-purpose, efficient trend graph for "live" data. Data is read in ASCII format from a file or continuously from a FIFO, and is played in real-time into a multi-pass trend (much like a CRT oscilloscope or a strip chart). trend can be used as a rapid analysis tool for progressive or time-based data series together with trivial scripting.
The Mesh Viewer is an easy-to-use, lightweight application for displaying three dimensional models (triangular meshes) from a variety of file formats. It uses OpenGL to render the models. Triangular meshes can be displayed texture mapped (with optional bilinear filtering), solid, or as a wire frame (all lines or just the front lines). Loaded models can be rotated, translated, and scaled (all done with the mouse). The model is lighted by multiple light sources. Viewpoints can be saved.
Dandelion is a 3D graph rendering application which can be controlled across a network. Its main purpose is to allow clear network graphs to be rendered in a window, which can be controlled by a separate application or the user. The Dandelion visualization is actually controlled by issuing simple commands to it across the network (although this could all be happening on a single machine). The Dandelion source includes a set of very simple libraries which can be incorporated into other applications and which can be used to send these commands. Libraries are included for C, C#, Java, and Python. The project was developed at Liverpool John Moores University within the PROTECT Centre.
The X3D library is used to load an X3D file and render it using OpenGL (an X3D file is an XML file describing a 3D environment that can be rendered with OpenGL.) The library supports all the objects as defined in the X3D specification in 2006. The render library is still somewhat limited, though. It works well under Linux. It is likely to work on any Unix, and has worked under MS Windows before. The project includes a test that makes use of FLTK version 2.0-m3. That version of FLTK can be downloaded from the project repository, as FLTK itself actually ended up not publishing a concrete 2.0 version of the library.
Castle Game Engine is a cross-platform 3D game engine written in Object Pascal. It includes a flexible system of 3D objects, with out-of-the-box levels, items, intelligent creatures, and more. Rendering and processing of 3D models in X3D, VRML, Collada, and other formats is implemented. Many graphic effects are available, including shadows, bump mapping, shaders, mirrors, and screen effects.
PRISCILA is a simple SDL/OpenGL presentation application with a keyboard-based WYSIWYG built-in editor. Its aim is to provide a vi-like tool to write presentations. The current editor is still very rudimentary and several editing actions have to be done by editing text files. Each presentation slide is a real 3D scene composed of several items. Special effects can be applied to modify item appearance, and actions can be added to modify items' behavior. 3D objects, effects, and actions are GNU/EDMA objects, which automatically provides plug-in support, easy updates, and more. An RFComm Bluetooth interface is included for remotely controlling a presentation from a mobile device.
