Object-oriented 3D Toolkit

MeVisLab makes extensive use of the Open Inventor library, an object-oriented 3D toolkit developed by Silicon Graphics (SGI) offering a comprehensive interactive graphics programming solution.

Open Inventor presents a programming model based on a 3D scene graph that simplifies graphics programming. It includes a rich set of objects such as cubes, polygons, text, materials, cameras, lights, trackballs, handle boxes, 3D viewers, and editors that speed up programming time and extend your 3D programming capabilities. Furthermore, it is easily extensible to add new functionality.

Open Inventor and MeVisLab

The MeVisLab implementation of Open Inventor is based on the original SGI source code that was released to the public in 2000. This implementation builds on Windows, MacOS X, and Linux on both 64- and 32-bit architectures and has been extended with various features, e.g., support for Vertex Buffer Objects.

MeVisLab Open Inventor can also be used independently of MeVisLab and is offered under the LGPL 2.1 license.

The sources of the MeVisLab Open Inventor implementation are included in the MeVisLab SDK installer.

We welcome any useful contribution to MeVisLab Open Inventor. If you feel you would like to share your improvements of the Open Inventor source code please contact info(at)mevislab.de and send us a patch.
