Sandra, I had the same problem, it is because there is a narrow convergence range in the z direction with the default interocular distance used. I used the following and it worked. SimpleUniverse u = new SimpleUniverse(c); PhysicalBody myBody = u.getViewer().getPhysicalBody(); myBody.setLeftE

Hi, I wouldn't call myself a pro at j3d, but it seems to me that you need separate Shape3d objects for each face. Since the rendering only looks at the shape (and may even subdivide quadralaterals) there is no way to control the appearance of a subset of a shape's geometry. As for the second
