- All Implemented Interfaces:
public class SoImageBackground extends SoBackgroundImage background node. Draws a background image.
This node provides a convenient way of rendering an image in the background of the scene. The position options like LOWER_LEFT can be used, for example, to place a logo in the corner of the window. The STRETCH and TILE options cause the image to fill the window and automatically adjust if the window size changes.
Note that the
SoImagenode can also be used to place an image in the scene, but the position of the image is specified in 3D coordinates. This node positions images relative to the physical drawing window.
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 image will be stretched or tiled across the entire virtual window.

public final SoSFFilePathString filenameNames file from which to read texture image. The standard image file formats are supported. See
SoRasterImageRWfor the list. If the filename is not an absolute path name, the list of directories maintained by
SoInputis searched. If the texture is not found in any of those directories, then the file is searched for relative to the directory from which the node was read. For example, if a node with a filename of "../tofu.rgb" is read from /usr/people/bob/models/food.iv, then /usr/people/bob/tofu.rgb will be read (assuming tofu.rgb isn't found in the directories maintained by
