5.5- An Inside Test Of Polygon By Winding No. Method Or Non Zero Winding No. In Computer Graphics

An Inside Test Of Polygon By Winding No. Method Or Non Zero Winding No. Method In Computer Graphics
In non-zero winding number method we need to know the direction of each edge in the polygon, i.e. whether the edge is clockwise or counter-clockwise. The winding number is number of times the polygon edges wind around a particular point in the counterclockwise direction.
Polygon Filling Algorithm - Learn about Computer Graphics in simple and easy ... Step 4 − Fill all those pair of coordinates that are inside polygons and ignore the .... Draw a scan line from the point to be test towards the left most of X direction.
Once the polygon is entered in the display file, we can draw the outline of the polygon. To show polygon as a solid object we have to set the pixels inside the polygon as well as pixels on the boundary of it.Now the question is how to determine whether or not a point is inside of a polygon. One simple method of doing this is to construct a line segment between the point in question and a point known to be outside the polygon, as shown in the figure (a). Now count how many intersections of the line segment with the polygon boundary occur. If there are an odd number of intersections, then the point in question is inside; otherwise it is outside. This method is called the even-odd method of determining polygon inside points.

In Our Channel Students can access computer graphics lectures with complete syllabus and all videos are in hindi language so they can understand easily. our motive to provide computer graphics lectures in hindi because it become easy for students to understand the concepts very easily and it took very less time so it also save your time as well.
Student will find many computer graphics tutorials in youtube but i guarantee that you will not find any other channel who teaches in easiest way as our channel does. Computer graphics videos are more in demand as it is is one of the most important subjects of many computer science streams.
As i already told that computer graphics videos in hindi is provided in our channel even all subjects are covered in hindi to make it easy. Many students follow books for computer graphics tutorials but it is not easy to understand from all things from the books so here is our channel who guides in many ways and hindi language make the concept the easiest.
Computer graphics is one of that subject which has been taught from very beginning in the school level.
The motive of making the computer graphics in hindi subject to make computer science students feel that it is very important and easy subject. Computer graphics lectures are provided by many lecturars but i ensure students that here you will find all lectures and many computer graphics notes with the making concepts clear. Notes Link:

Nice teaching method sir i love your teaching method ♥️

[@yugaluk0710]

Sir agr point extreme left ya right me edge m se guzarta hai to value kya lenge ?

[@ritudash3664]

Sir thanks for these amazing videos these were really helpful for my exams.

[@adityakalhan812]

sir what will happen if the line that we draw from the point cuts a vertex? will we follow something similar to the previous video?

[@omkarbhoir9819]
