The polygon is said to be convex if we travel either continuously clockwise, or continuously anti-clockwise. If a polygon fails this test, it is said to be not convex. ... The following are examples of convex and not-convex polygons: ... The above polygons are represented by the respective co-ordinates:

CiteSeerX - Document Details (Isaac Councill, Lee Giles): . We prove that there is a motion from any convex polygon to any convex polygon with the same counterclockwise sequence of edge lengths, that preserves the lengths of the edges, and keeps the polygon convex at all times. ... 13 Convexifying monotone polygons – Biedl,

The equations are valid for all convex polygons of n33. Numerical Example: Hexagon; We start with a convex hexagon randomly generated with a node at !1,0". The element is shown in Fig. 5. The nodes are;

Although shape 1 and shape 3 seem to follow the rule of convex polygons, shape 2 seems to me non-convex since I can connect points 2 and 4 into a line segment that doesn't fall in the polygon. Can we say that the OpenGL Architecture Review board where wrong about what they described in the redbook?

Introduction to figures and polygons. Brought to you by Math League Multimedia. ... The following are examples of polygons: ... A figure is convex if every line segment drawn between any two points inside the figure lies entirely inside the figure. A figure that is not convex is called a concave figure.
