Hi,guys:
about winding in opengl,i have a little confusion!

The combination of order and direction in which the vertices are specified is called winding

If you view this triangle being
drawn from the direction in which the normal vector points, the corners appear counterclockwise
around the triangle. This is called polygon winding
So,the first winding is the same as the second winding???
Sorry,new to opengl and 3d graphics!

First quote applies to GL.
Second is not completely exact, because there is no need of normal to define polygon winding.
