An application that wants to run on a cluster just needs to open a ClusterWindow that can distribute all changes across the cluster and can very easily drive a Powerwall or a CAVE without having to worry about distribution protocols and other complications.

It features a blocked state management system to reduce the overhead for state change optimization, highly flexible traversal and other mechanisms to allow run-time exchange and enhancement of core data structures, but the most unusual aspect is its multi-threading approach.

The state of the scene graph is represented by the whole scene graph, only protecting individual nodes can still lead to inconsistent results e. Languages Deutsch Edit links.

The work is concerned with three main parts: Wolfram KresseDirk Reiners. I started with pure OpenGL but then I found those scene graph libraries which are looking quite nice.

The API encapsulates a mesh Management and visualisation of non-linear history of polygonal 3D models Jozef Dobos. In this paper, we propose an approach for rendering diffuse and glossy reflections using environment maps. Retrieved from " https: Image-space occlusion culling is an useful approach to reduce the rendering load of large polygonal models in scienti c computing, mechanical engineering, or virtual medicine. Asked 6 years, 5 months ago. Development on both started about the same time, and both opengs similar names.

The Bidirectional Texture Function BTF is a suitable representation for opesng appearance of highly detailed surface structures under varying illumination and viewing opens.

The Complete Reference Heather Williamson. The same mechanism also allows highly flexible and effective clustering. Lowering the entry barrier for students programming virtual reality applications Martin Lambers.

I'm resigning as a moderator from all Stack Exchange sites, effective today. Author Fellner, Dieter W. The Eurographics Association The design of the frameworks is inspired by the OpenInventor oprnsg functionality, OpenSG uses selective multi-buffering, by duplicating opnsg small parts of the graph for each thread that needs to be protected while sharing the bulk data like vertex arrays and texture images, and only duplicating these using a copy on write mechanism.

Stack Overflow works best with JavaScript enabled.

To synchronize an application running on several machines, only the changes for each frame are sent to each machine and integrated into the local scene graph. Scene graphs are notoriously hard targets for multi-threading, as they contain very large data structures easily consuming hundreds of megabytes opwnsg memory. Can we trust that image?

Citations Publications citing this paper. This way the distinction between local and remote changes is almost invisible.
