Hi Marco, I have done it by adding a second cube and then setting the render
parameters
for this second cube to render in wireframe mode. Just add the second cube in the same
BG/TG as the the first one, so they have the same translation and rotation.
This is the code to let the cube render in wireframe mode:
Appearance app = new Appearance();
// Select the color for wireframe lines
Color3f objColor = col;
ColoringAttributes ca = new ColoringAttributes();
ca.setColor(objColor);
app.setColoringAttributes(ca);
// Here you set the width for the lines in wireframe
// (as long as I know changing line width just works for OpenGL version).
LineAttributes la = new LineAttributes();
la.setLineWidth(3);
la.setLineAntialiasingEnable(false); // Setting antialising to true it far more
slower.
app.setLineAttributes(la);
// This will force render in wireframe mode for the cube.
PolygonAttributes pa = new PolygonAttributes();
pa.setPolygonMode(pa.POLYGON_LINE);
pa.setCullFace(pa.CULL_NONE);
app.setPolygonAttributes(pa);
YourCube.setAppearance(app);
Greetings from Spain
Hope it helps
