boundary-fill algorithm or flood-fill algorithm
As you saw the implementation of scan line polygon fill requires that boundaries should be straight line segments. The seed fill algorithms do not require any such constraints. You only need to know an interior point of the closed boundary object to fill it. This interior point is called a seed point.
However, determination of interior point for complex polygons such as the one shown in figure itself is a challenging task.The following methods are used to determine an interior point of the area to be filled.
1. Odd-even rule,
2. Nonzero winding number rule.
Once an interior point of the object is determined, the boundary-fill algorithm or, flood-fill algorithm may be applied to fill the given area.

Can you give some basic features of computer graphics? The methods of computer graphics are the manipulation and creation of graphics (artificial images) by computer.
What is reflection and clipping? The reflection is actually the transformation that makes a mirror image of an object. For this use some angles and lines of reflection. Cli
Transformation for 3-D Rotation Rotation in 3-dimensions is considerably more complicated then rotation in 2-dimensions. In 2-Dimentional, a rotation is prescribed via an angl
To reflect the ball off of the polyline, we need to re?ect it off of the segment that had the minimum thit. But the reflection computation depends only on t hit , n, P and v, so th
