Detailed Description

Gradient background node.

Draws a color gradient background.

This node provides a convenient way of drawing a color gradient background for a scene. The first color (color0) appears at the bottom of the window and the second color (color1) appears at the top of the window. Rendering of the gradient is automatically recalculated if the window size changes.

Generally background nodes should be placed at the beginning of the scene graph so that geometry is drawn on top of the background. Background nodes have no size, are not pickable, and do not modify the OpenGL depth buffer.

Another convenient feature is that this node renders correctly on a tiled display that represents a single large virtual window, for example using the MultiPipe extension (see SoXtMPExaminerViewer). The gradient will be interpolated smoothly across the entire virtual window.
