Surface plots show a 2D image as a 3D plot, where the 3rd dimension is given by the intensity. Because only one slice of an image stack can be displayed a time, SurfacePlot2D offers a method to set the displayed slice:
	// Add the image as a volume
	Content c = univ.addSurfacePlot(imp);

	// Retrieve the SurfacePlotGroup
	SurfacePlotGroup splot = (SurfacePlotGroup)c.getContent();

	// Scroll through the slices
	for(int i = 0; i < 15; i++) {
		splot.setSlice(i + 1);
