the next step is to learn how to create your own shapes.
First create an Appearance
Appearance polygon1Appearance = new Appearance();
Lets make a simple Rectangle:
in this example, the rectangle will have height of 3m and width of 2m,
with coordinates (0,0,0), (2,0,0), (2,3,0) and (0,3,0)
(notice the veritices are in counter-clockwise order)
QuadArray polygon1 = new QuadArray (4, QuadArray.COORDINATES); polygon1.setCoordinate (0, new Point3f (0f, 0f, 0f)); polygon1.setCoordinate (1, new Point3f (2f, 0f, 0f)); polygon1.setCoordinate (2, new Point3f (2f, 3f, 0f)); polygon1.setCoordinate (3, new Point3f (0f, 3f, 0f));
Then add the Polygon to the Scene Graph using that Appearance (assuming objRoot is your SceneGraph name)
Note: If you do not put your verticies in counter-clockwise order, they will not be seen.
