Hi, Kyle, Renoir: Thanks very much for you guys's meaningful hints. I got it. What I am doing now is just as Renoir suggests, draw the outline of the original polygon in lineArray, and then draw the polygon using GeometryInfo class.
Actually, I don't care the outline when in shading mode, so didn't use the ordered group. I just hope when in wireframe mode, no extra lines are displayed, because that's annoying. In this mode, I set the PolygonMode as POLYGON_POINT, so all the edges for those triangles are not displayed, only the outline for the original polygons got displayed. This is not very good, because we have to draw twice. I don't know why J3D desn't provide show/hide edge as OpenGL does. Anyway, it works. Cheers, white.
