Detailed Description

The DtRenderer is the component responsible for rendering 3D images onto the screen.

The component responsible for drawing 3D images onto a screen is the DtRenderer. Each display engine owns one. The DtRenderer provides an interface for updating the scene graph and rendering the scene. Its update() and render() functions are called each display engine tick.

The core VR-Vantage Toolkit framework abstracts away from the underlying rendering implementation. This separation ensures that the rendering-independent code remains independent of OSG, while the rendering code exists in the libraries that depend on OSG. (VR-Vantage can support alternate rendering solutions.)
