The following is taken from the 1.1.2 javadoc for the Raster object. http://java.sun.com/products/java-media/3D/forDevelopers/j3dapi/javax/media/j3d/Raster.html "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." -- Kevin Rushforth Java 3D Team Sun Microsystems [EMAIL PROTECTED] >Date: Thu, 26 Aug 1999 16:37:46 -0700 >From: John Sutter <[EMAIL PROTECTED]> >Subject: Re: [JAVA3D] A Raster Shape3D is not pickable >To: [EMAIL PROTECTED] > >Did you ever hear anything back on this?
