CADauno is a 3D modeling tool based on the NURBS surfaces. It aims to exploit the power of NURBS at representing free forms. It provides an interpolation facility ("skinning" technique), which enables the designer to create a closed surface passing through different section curves. This makes it possible, as an example, to build a human body 3D model starting from sections provided by a Computed Axial Tomography scanner.
Coin is an implementation of Open Inventor. Open Inventor is the de facto standard API for retained-mode 3D graphics programming. Open Inventor has a highly extensible design, and has been designed to allow for rapid development of highly interactive 3D graphics applications in the fields of CAD, engineering, scientific computing, simulation, VRML, and visualization.
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.
Convex 3D is a convertor, extractor, and viewer for such popular 3D formats as 3DS, Wavefront OBJ, and Lightwave 3D. It is written in C++ and uses a modular design. The package includes a standalone conversion tool (console) and GUI application (Qt and OpenGL are required) for viewing and more. It is not meant to be a modeler, but it can be a powerful tool to hack into 3D files made by 3rd party modelers.
Deciduous Evolution uses a 3D recursive algorithm for drawing binary trees using intersecting cylinders in 3D space. All adjustable aspects of this algorithm are parameterized, and these parameters are evolved using a genetic algorithm. Statistics describing various metrics of the tree are instantiated, and fitness is calculated based on a number of weighted functions of these statistics. The goal of this project is to manipulate these weights to most accurately reflect the laws of nature, and observe the resulting trees. Using only a simple set of parameters, a recursive binary tree's growth can strikingly resemble that found in nature.
Dice3DS is a set of Pure Python modules for dealing with 3D Studio format (*.3ds) files. It maps 3DS chunks into a hierarchical set of Python objects; it's a lot like how ElementTree works for XML files. Dice3DS requires Python 2.6 or higher and Numpy. Note that it is not a wrapper for lib3ds.
