It contains a 3D point that is defined in the local object coordinate system of the Shape3D node that references the Raster. It also contains a type specifier, a clipping mode, a reference to a ImageComponent2D object and/or a DepthComponent object, an integer x,y source offset and a size (width, height) to allow reading or writing a portion of the referenced image, and an integer x,y destination offset to position the raster relative to the transformed 3D point. In addition to being used as a type of geometry for drawing, a Raster may be used to readback pixel data (color and/or z-buffer) from the frame buffer in immediate mode. <p> The geometric extent of a Raster object is a single 3D point, specified by the raster position. This means that geometry-based picking or collision with a Raster object will only intersect the object at this single point; the 2D raster image is neither pickable nor collidable.<P><P><HR><P><!--
