About using drawTriangles()

Another advanced method introduced in Flash Player 10 and Adobe AIR 1.5, Graphics.drawTriangles(), is like the Graphics.drawPath() method. The Graphics.drawTriangles() method also uses a Vector.<Number> object to specify point locations for drawing a path.

However, the real purpose for the Graphics.drawTriangles() method is to facilitate three-dimensional effects through ActionScript. For information about using Graphics.drawTriangles() to produce three-dimensional effects, see Using triangles for 3D effects.
