Lifting the Stone (calculate the center of gravity of any polygon)Lifting the StoneTime Limit: 2000/1000 MS (Java/Others) Memory Limit: 65536/32768 K (Java/Others)Total Submission (s): 5432 Accepted Submission (s): 2273Problem DescriptionThere are eclipsecret openings in the floor which are covered by a big heavy stone. when the stone is lifted up, a special mechanic detects this and activates initialize ONED arrows that are shot near the opening. the

The main idea: start with the origin and then add an x, Y value each time, find out how many points at the end of the polygon edge, how many internal points, polygon area is how much.Analysis:1, with the lattice point as the vertex of the line segment, the number of points covered is gcd (Dx,dy), wherein, dxdy respectively for the segment of the horizontal and vertical points accounted for. If DX or dy is 0

To give you illustrator software users to detailed analysis to share the design cool fashion polygon background of the drawing tutorial. Tutorial Sharing: First open the illustrator, draw a square on the artboard, then select the Pen tool, randomly draw the curve, through the square. You can turn on the smart Guides (ctrl+u) so that you can snap to existing points and continue to draw some of these lines. C

To give you illustrator software users to detailed analysis to share the creation of polygonal paper effect of ice cream painting system tutorial. Tutorial Sharing: The points we will be learning in this tutorial are: Application of BLOB Brush tool Polygon Construction The use of textures Gradient fill One, hand-painted modeling The so-called hand-painted modeling, in fact, is j

First, with transform panel We take positive Pentagon as an example 1, create a new file, in the scene to draw a straight line, press F8 into the film, the center as the upper left corner, as shown in Figure 1 Figure 1: The center is set in the upper left corner 2, select the line, press Ctrl+t to pull out the transform panel, and in the Rotate box to enter 72 (360/5), the angle of calculation is 360 degrees divided by the number of edges. As shown in Figure 2 Figure 2:transform Panel 3, press

Polygon game (DP), game dpDescription A polygon game is a single player game.NPolygon composed of vertices. Each vertex is assigned an integer, and each edge is assigned an operator "+" or "*". All edges are sequentially rounded up from 1NId. In step 2 of the game, delete an edge. SubsequentN-Perform the following operations in Step 1: (1) Select an edgeEAndETwo Connected verticesV1AndV2; (2) Replacing edge

Title Link: http://poj.org/problem?id=2007Test instructions: The vertex coordinates of a convex polygon are given in order to output each vertex in a counter-clockwise sequence. The first point given must be (0,0), there is no other point on the axis, there is no three-point collinear situation.Can be used to sort the cross product, vector p1xp2 > 0 shows that p1 counter-clockwise rotation /*in order to give the vertex coordinates of convex

This program is used to draw a color rotation regular polygon in AutoCAD in line for viewing ~This program is affiliated with Magictable (can be downloaded to the Cloud website: http://www.yiyunsoftware.com/), installed to use the program.After the download is installed in the AutoCAD command line output such as WP command, you can choose to fill in the parameters, click "OK", specify a point on the screen, a few seconds to draw a brilliant color rota

To find the distance from the point to the straight line:Double dis (point p1,point p2){if (Fabs (p1.x-p2.x) {return Fabs (P2.X-PEGX);}Else{Double k= (P2.Y-P1.Y)/(p2.x-p1.x);Double b=p2.y-k*p2.x;return Fabs (k*pegx-pegy+b)/sqrt (k*k+1);//return distance}}Determine whether a polygon is convexIf the hole contains any protrusions (i.e), if there exist any of interior points in the hole so, if connected by a Lin e segment, that segment would cross one or

Given a (x0, y0) B (x1, y1) C (x2, y2)1. Ask for 3 sides a,b,c2. Seek circumscribed circle radius first. (Must exist)Helen Formula + sine theorem get R = a * b * C/(4 * s) s = sqrt (Q * (q-a) * (q-b) * (q-c)); Q = (A + B + c)/2;-----because it's regular polygon. Then just ask for one side with two radii of area * N is good.3. Cosine theorem for 3 angles. Seeking greatest common divisor is the smallest angle regular
