5.1. Overview

The DirectViz extension allows Open Inventor applications to render 3D scenes with very high realism and scalability by using the Real-Time Ray-tracing engine OpenRTRT™ as an alternative to OpenGL. DirectViz addresses the demanding needs of styling and conceptual design, virtual prototyping, and visual simulation that are not currently satisfied by graphics processors and OpenGL. This section introduces the main concepts and benefits of OpenRTRT and DirectViz.

DirectViz is a separately licensed extension. You must have a DirectViz license string in addition to your Open Inventor license string. One of its fields specifies the maximum number of ray-tracing cores that are used for rendering.
