s3d is an XML schema for 3d scenes, objects, and so forth (intended primarily but not exclusively for computer games). The problem is that often as a games developer you need to work with many 3d editing tools and rendering engines, and there should be an easy and portable way to move objects, levels, etc. around. By having a common intermediate file format, you only need to write one exporter per tool and one importer per graphics engine. Also, you can develop generic tools which are not tied to any particular engine.
The CoinXtension library is a small extension to the easy-to-use "Coin 3D" graphics framework. It offers some additional operators for the existing data types in Coin 3D, but more importantly it extends the linear algebra capabilities of the original framework by adding the new SbXtMatrix3d data typ. This offers such useful routines as eigenvalues and QR-decomposition. It also provides a SbXtQuaternion class for quaternion representation.
The Deimos Project is a 3D space combat simulator and modular game library collection. It includes a 3D modeler designed with a programmer's needs in mind. It allows you to construct 3D models by writing Java source code. All you need to design a model is a computer, some graph paper, and a pencil. The modeler's internals function as a simple OpenGL scene graph API, without preventing the use of low-level OpenGL commands. For storing settings and other hierarchically-representable data, the project provides a Hierarchy library that stores data atomically using XML. It also features a timing library, a game object container system, and many other features.
VCG TriMeshInfo is a tool designed to inspect 3D models and retrieve many types of topological and geometrical information from them. It can be used to automate the process of decoding 3D mesh inherent properties and ease data classification and retrieval. For each analyzed dataset, the following data are extracted: number of vertices, number of faces, number of edges, number of connected components, number of boundaries, number of isolated (i.e. unreferenced) vertices, manifold, genus (computed only for manifold datasets), orientability, orientation, regularity, number of duplicated vertices, and self-intersection.
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.
myOS is a minimalistic, OpenGL capable, GNU/Linux-based system without X. It is a bare bones Linux system, stripped of everything but the files necessary to compile and run OpenGL/C code. It has a simplified directory structure and a cleaned-up internal cross referencing. It has two available variants. myOSx-less fits within a 64 MB RAM disk and features a WebKit based on Trolltech's Qtopia demo Web browser. myOSx is oriented for X11, and its development tools are built around Trolltech Qtopia to produce applications based on the WebKit and for the framebuffer of the original myOS system.
