Does a point lie inside a polygon - Milgram - 1989 () Citation Context ...s dynamics. Here, we use the hybrid grid to get a unique denition of the boundary of the computational domain. It is important that the boundary be unique since we employ the ray method (see Milgram =-=[10]...
The point-in-polygon algorithm allows you to programmatically check if a particular point is inside a polygon or outside of it. A common way to tackle the problem is to count how many times a line drawn from the point (in any direction) intersects with the polygon boundary. If the line ...
The number of intersections for a ray passing from the exterior of the polygon to any point; if odd, it shows that the point lies inside the polygon. If it is even, the point lies outside the polygon; this test also works in three dimensions. One simple way of finding whether the poi...
If the test point is on the border of the polygon, this algorithm will deliver unpredictable results; i.e. the result may be “inside” or “outside” depending on arbitrary factors such as how the polygon is oriented with respect to the coordinate system. (That is not generally a problem...
We define first a quasi-closest point that can be locally found through the uniform subdivision cells, and then we provide the criteria for determining whether a point lies inside a polygon according to the quasi-closest point. For a large number of points to be tested against the same ...
the point is inside the polygon (Figure 3). Unlike the convex test, where an intersection means that the test is done, all the triangles must be tested against the point for the non-convex test. Also, for the non-convex test there may be multiple barycentric coordinates for a given point...
