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.
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.
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.
The Whole Brain Catalog is a 3D virtual environment to facilitate solutions for currently intractable challenges in brain research. It is meant to enable the synthesis of data measured from brains at different scales into more coherent models of brain structure and function. The Whole Brain Catalog is a client-server platform that provides rich 3D views for researchers to zoom in, out, and around structures deep in a multi-scale spatial framework of the mouse brain. A 3D graphics engine used in graphics-intensive computer gaming generates high-resolution visualizations that bring data to life through biological simulations and animations.
San Le's Free Computational Electromagnetics (SLFCEM) is a package of scientific software for use in computational electromagnetics. Command-line driven calculation engines are separate from the GUI components and can be used independently. It includes two of the basic finite elements types, 4 node quad and 3 node triangle. Each element type has a unique GUI specific to the element. Modal analysis for solving the waveguide problem is done using edge based elements. There is also code for generating edge connectivity. The algorithm used is a combination of Lanczos for tridiagonalization of the system, as well as QR to calculate the resulting eigenvalues. In addition to skyline storage and LU decomposition, calculations are also made using the Conjugate Gradient Method.
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.
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.
