ABSTRACT

This paper presents Open Inventor extensions for working with offline divided models over a network. There are in fact two extensions. The first one adds a functionality for downloading models and textures from a network. There is allowed a non blocking texture and model downloading. The second one extension adds a functionality for maintain level of detail for downloaded textures. The main purpose for maintain level of detail for textures is in saving maximum free memory. Open inventor is object oriented library for interactive working with 3D grapics and is based on synchronous scene graph traversal. On the other hand these two extensions is asynchronous. We also present a possibilities to synchronize these extensions and the scene graph traversal. 1
