If you want a silhouette, then a neat trick is to render your mesh as normal. Then set line thickness to some value, and depth-test to EQUAL, and render back-faces instead of front-faces in wireframe. An alternative would be to use RTT and apply an edge filter via a fragment shader. -J ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
