Скачать или смотреть odd even rule computer graphics | Inside Outside Test For Area Filling Algorithm

In this video we will be learning about odd even rule for inside outside test for area filling in computer graphics.
In Odd-even rule we draw a line from any position P to a distant point outside the coordinate extents of the object and count the number of edges crossings along the line.
If the number of edges crossed by the line is ODD then the Point P is in the interior.
If the number of edges crossed by the line is EVEN then the Point P is in the exterior.

CONDITION for Odd-even rule:
You need to make sure that the line drawn from the point P does not intersect a vertex or endpoint.
EXAMPLE: ODD-EVEN RULE
