Hello, V. Zudin, you wrote: SVZ> Confused a mention winding'. I thought that depth a circuit enclosure (0,1,2 is considered... On a picture). . So depth actually also is considered. Produced algorithm value s = 0 - the point means does not belong to a polygon. Produced value s = 1 - means belongs. Produced value s = 2 - means does not belong by rule ODD, but belongs by rule POSITIVE. And so on. Actually, the algorithm only also does that calculates depth of an enclosure. What here can confuse?

Look at this decision, it denies classical geometry (the corner does not exist, there is a direction change). http://files.rsdn.org/125374/sg.png

#### Re: Point hit in a circuit

through it the challenging task dared more - the intersection (superimposing of figures), there the decision was reduced to a difference of vectors. Well and a classical rational way such tasks do not dare.

How many peaks are required for the description of such polygon? 2. How search of points on a surface on which the accessory of a point to a polygon is defined is fulfilled?

How search of points on a surface on which the accessory of a point to a polygon is defined is fulfilled? 1. The figure is described in the vectorial form, there is no concept of peaks and this concept is not used. As there is no concept of a corner for the arbitrary curve. The corner is concept from ancient geometry which is not real also to which there is no even an accurate determination - on sense this increment of a vector at the curve description, simplified to one point. 2. Such surface is described elementarily - by sampling of the following point on the basis of a current vector. The problem can be only standard - selection of noise on the image, join of parts and ; these are recognition problems. On the basis of this idea very much for a long time has been implemented  fillings of figures. More precisely so it is not correct to name, this selection of all integer parts (circuits) within considered region.
