VtkExtension is a heterogenous library of C++ classes for use with VTK. Included are additional geometry sources, extended collection classes, extended XML parser and string facilities, as well as composite classes abstracting larger application needs.
freetsx - free plug-ins, shaders and tools for trueSpace (3D modeling-animating software by Caligari).
JBean3D project aims to develop JavaBeans components representing classes in Java3D.
sjgui is a gui framework for use in interactive OpenGL applications. The main goal is to provide very easy and fast way to develop portable interactive interfaces, using object-oriented approach. It is easily extendable to suit your needs and is platform
The extremely popular coolpowers series of plugins and shaders for Caligari trueSpace is now an open community project. From cel shading to blurred reflections, from glowing effects to landscape generation, there is something here for everyone. Power up
MindEngine is an API-independent and cross-platform 3D engine written in C++. It is completely modular in design with a fully-working plug-in system and supports OpenGL and Direct3D rendering APIs with the aim to one day include support console systems.
CSJB (Crystal Space Java Binding) is a package of java classes, that can interface with the Crystal Space 3D engine, via Java's Java Native Interface (JNI).
Straylight is a geometry visualization system which is tightly integrated with the Geomatrix geometry engine.
C/C++ library with functions and datastructures which come in handy with 3D programming. F.e. it contains a 3Dstudio MAX' ASE importer/compiler, vectormath functions etc. It's developed as an add-on library for DemoGL, but can be used by any other program
OpenGL bindings for Objective Caml programming language.
R.I.S.E. is a state of the art engine and framework for the simulation and realistic image synthesis of natural phenomenon based on physics, biology and chemistry.
Terrain Voyager Engine is an OpenGL accelerated, multi-platform (Win32, Linux, IRIX) landscape engine. One of the goal of it is to make a small FPS game.
OpenGL Based, C++, Win32 execution platform for your audiovisual effects. It allows you to develop standalone executables or screensavers (win32). Just program the graphical effects as objects and schedule them using an easy script.
tdmagic is an Open Source library for scripted procedural modeling, texturing and animation.
A fast and lean render engine with multiple renderbackends
TacitPixel is a scalable C++ framework for building application prototypes for interactive collaborative VR/AR applications. It provides a number of features that make prototyping fast and portable. TacitPixel is the successor of the TAP and Twisted Pair engines.
Owl-Blender takes a properly annotated OWL file as input and outputs a Blender file to create a 3D visualization of the ontology.
The software for solving special problems of mathematics and physics
The project "FD-Method For Solving PDEs" contains the software for solving the nonlinear Klein-Gordon equations (see www.arxiv.org/abs/1203.5979 for more detail). The project "Infinite systems of matrix equations" consists in developing algorithms and software for solving systems of matrix equations. In the present version the project allows one to solve an infinite system of matrix equations which arises in the theory of stability preserving structural transformations of systems of second-order ODEs (see http://arxiv.org/abs/1204.1814). The project "Nonlinear Stourm-Liouville Problems with Distribution Potentials" is developed for solving nonlinear Sturm-Liouville problems with integrable potentials including Dirac delta function. The numerical-analytical method used in the project is called the FD-method. It was first proposed by Professor V.L.Makarov in 1991.To learn more about the problems of such type and the FD-method see, for example, http://arxiv.org/abs/1112.2540.
