Enlarge a polygon that has colinear vertices in C#
The example Enlarge a polygon in C# shows how you can expand a polygon. The basic idea is to offset each of the polygon’s edges away from the polygon’s center and then see where adjacent edges intersect as shown in … Continue reading
Pingback: Code Project post “Clipping Plane in WPF 3D”

Sprialize an image in C#
This example shows how to spiralize an image. By spiralize I mean shade pieces of the picture with different colors so the colored areas for a spiral as shown in the picture. This could be a difficult problem. Fortunately I’ve … Continue reading
Fill a target area found by trilateration in C#
The post Perform trilateration in C# explains how a C# program can use trilateration to find an area where a target point lies. This post explains how you can draw that area. The Target Area The target area found by … Continue reading

Perform trilateration in C#
This post explains how a C# program can use trilateration to locate a point that is known distances from three other points. Trilateration is somewhat similar to triangulation, so following two sections begin by explaining what triangulation and trilateration are. … Continue reading

Draw many circles that intersect two points in C#
As I mentioned in my earlier post Connect two points with elliptical arcs in C#, an infinite number of circles (or ellipses) can pass through two points. This example draws some of them to produce an interesting pattern. This example … Continue reading

Connect two points with elliptical arcs in C#
As I mentioned in my earlier post Connect two points with arcs of midpoint circles in C#, two points alone cannot uniquely define a circle. An infinite number of circles (or ellipses) can pass through two points and therefore they … Continue reading

Connect two points with arcs of midpoint circles in C#
Two points alone cannot uniquely define a circle because an infinite number of circles can pass through two points and therefore they can be connected by an infinite number of arcs. If you add extra information, however, two points can … Continue reading
