Open Inventor and Large Model Visualization (LMV) -- The Solution for Large Model Visualization

In order to visualize graphics quickly, we have to be clever in choosing which primitives we feed to the graphics pipeline. The demand for increasingly complex 3D graphics models is growing faster than graphics workstation hardware can keep up. The only solution left is to find ways to represent models and scenes with fewer graphics primitives, and to send only the needed primitives to the graphics pipeline.

Since Open Inventor 2.4, there have been techniques to enhance large model visualization with view frustum culling and caching mechanisms and levels of detail. Starting with Open Inventor 2.5, we have gone further and added new techniques for visualization of large models and assemblies, as described below.
