As Mathias and Tom pointed out, you can capture the image as a BufferedImage or as a JPEG file. A slick way to move images from a DisplayImpl on one machine to a RemoteSlaveDisplayImpl on another machine is illustrated in visad/examples/Test64.java (client) and Test63.java (server). This allows mouse interactions on the client machine to be aplied to the original display on the server machine. As you point out, you can also send the original data between machines and attach it to a new DisplayImpl. The intermediate level, the Java3D scene graph, is not Serializable. But VisAD has its own internal scene graph classes that are Serializable. These are used by DisplayImplJ2D. Also, a DisplayImplJ3D creates a Serializable internal scene graph first, then converts it to a Java3D scene graph. The visad.cluster package uses this with custom Java3D DataRenderers that create Serializable internal scene graphs on cluster nodes, send them to a client, where they are merged and converted to a Java3D scene graph. But custom DataRenderers are a little deep for what you want to do. I think the RemoteSlaveDisplayImpl, or the JPEG file, is the right approach for your problem.
