My main view has several (perhaps many) polygonal active areas implemented as subviews. When the user touches the view, I want to identify if she hit one of those active areas.
Im craeating a dart scoring program (to use myself in my dart room) and want the user to be able to click in different areas of a picture of a dart board to register the thrown darts.
We need to figure out a quick and fairly accurate method for point-in-polygon for lat/long values and polygons over google maps. After some research - came across some posts about mysql geometric exte
I have been trying to figure out how to write a simple program to compute the x,y points for creating a regular polygon of n sides. Can someone give me some code examples that don\'t use preexisting f
What is the fastest way to find if a point is in a rectangle given in this form: I have two points which are the centers of opposite sides of the rectangle, and a number which is the height of those s
I have been looking at posts about determining if a point lies within a polygon or not and the answers are either too vague, abstract, or complex for me.So I am going to try to ask my question specifi
I\'m wondering what may be the most efficient way of determining whether a large number of points (O(1 million) are inside or outside a collection (O(10)) of polygons?The latter are not necessarily co
i have a typical question with the Geometric datatype of mysql, polygon. I have the polygon data, in the form of an a开发者_Go百科rray of latitudes and longitudes, ex:
I have a map that I converted from a raster graphic into an SVG file by converting the di开发者_高级运维fferently coloured areas into paths.
I can\'t figure out how to implement this in a performing way, so I decided to ask you guys. I have a list of rectangles - actually atm only squares, but I might have to migrate to rectangles later,
