Hello cj, basically for drawing different stuff you can use any of the scenegraph nodes in <ACG/Scenegraph>.

In PolygonMode you can add a bunch of points with add_point(const Vec3d& _v) and the lines connecting the points the in added order are then drawn. Alternatively you can use add_line(const Vec3d& _v0, const Vec3d& _v1) to draw a bunch of separate lines. //Henrik For example basically you can use the you can use On Thu, 15 Dec 2011 22:04:27 +0800 canjiang ren <rencanjiang@gmail.com> wrote:

Thank you very much. cj
