bluetooth triangulation

The main topic: according to the order of the clockwise or counter-clockwise to give a multilateral point, to break this polygon into a n-2 triangle, the requirements of these triangular rows of the largest area of the Triangle area as small as possible, to find the minimum value.Ideas: with the interval DP can be easily solved, The polygon may be a concave shape, note that the triangle must be inside the polygon, so you can remove the split triangle contains other points, but other in the polyg

Question-related definitions: (1) triangular subdivision of convex polygon : A set of chords that divides a convex polygon into a disjoint triangle. (2) Optimal split : A given convex polygon p, and a weight function w defined on a triangle that consists of a polygon's edge chord. It is required to determine the triangulation of the convex polygon, so that the sum of the weights in the triangles is minimized. To split the case. If Convex (n+1) edge

Polygon: A piecewise linear closed curve on a plane. which consists of a series of straight line segments.? A convex polygon is usually represented by a counter-clockwise sequence of polygonal vertices, that is, P = {v0,v1,...,

This paper mainly discusses the algorithm to extend the line into 2d line surface.It's easy to extend the P0P1 line into a polygon.vec2f line = P1-p0vec2f normal = vec2f (-line.y, line.x). Normalized () .vec2f A = p0-thickness * normal;vec2f B = p0 + thickness * normal;vec2f c = p1-thickness * normal;vec2f d = p1 + thickness * normal;If this is a straight line, but if there is a polyline, we also need to calculate the intersection point whereFirst we'll find out tvec2fT= ((P2-P1). Normalized ()

In the practice of looping statements, it is a classic example to draw a positive triangle, but if the method is not the right one, the resulting code is very complex and not highly applied.There are two ways to draw the positive triangle, the first is a more troublesome approach, is through the induction of each row and column and the required triangle of the intrinsic relationship obtained, more cumbersomePackage complementation;public class Trangle {public static void Main (string[] args) {in

Bluetooth 1.2 vs 1.1: 1. Adaptive Frequency Hopping (AFH ):Adaptive Frequency Hopping TechnologyThe main function is to reduce interference problems between Bluetooth products and other wireless communication devices. 2. Extended synchronous connection-oriented links (ESCO ):Extended synchronous link-oriented channel technologyIt is used to provide audio transmission with high QoS, and can further meet the

equations. There are three types of solutions for a: 1. Give 4 match points to get a 8X9 formula, and rank (A) = 8. So the null-space of a is a solution. 2. When there are more than 4 points, we need to solve the super-definite solution. The solution we want is the singular vector corresponding to the smallest singular value of a. 3. Since the solution of H depends on a coefficient scale, we can constrain h by changing the coefficients. If we make h3,3 1, then we get For n points, our solution
