Front and Back sides of a polygon
Posted on 2006-05-12
Can anyone tell me how do I determine the FRONT and BACK side of a polygon?
is it true that the +Z face is always the back, the -Z face is always the front?
I'm asking this becoz my glLighting isn't lighting my model correctly ... even though it did light the glutWireTeapot and glutSolidTeapot properly.
Please reply asap, I need to know it urgently...
PS, i read some articles that suggests that the FRONT and BACK are determined by the way you place ur vertices in between glBegin and glEnd... pls comment on that too.
Thanks A LOT!
