rfid triangulation

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

Before accidentally see Ovilia with Threejs did a low POLY, that is, the effect of the image plane triangulation, feel very stunning, and then took a little time to try. I did not use the Threejs, so I use the Canvas 2d drawing API directly, because it seems that the effect is not threejs. Directly on the demo: http://whxaxes.github.io/canvas-test/src/Funny-demo/lowpoly/index.html (also can be seen on the mobile side, but because of the large amount

The course report for a course in the undergraduate course period ~~ The content includes introduction to RFID, market application and prospects, working principles, risks, security and privacy policies, and a total of 5 points. Because the length is too long, we will divide it into two blog articles. The first part of this article is the introduction, market application and prospects, and working principles. 1.

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

From software to hardware, IBM and other companies have long been equipped with RFID (Radio Frequency identification, radio frequency identification) technology, users are full of expectations. IDTechEx Company's latest survey shows that, including systems and services, the RFID market will rise from 2.7 billion U.S. dollars in 2006 to 12.3 billion U.S. dollars in 2010, to 2016 market size will likely expa
