Recently, I helped someone solve a problem. How can I determine whether a coordinate point is in a polygon area (two-dimensional ). I searched for a circle on the Internet and wrote my own code. There are multiple algorithms, such as convex polygon and concave polygon. In short, this is troublesome. Continue searching and learn that there are ready-made class functions in Java/dotnet class libraries to solve this problem. Considering that there are not many people familiar with it, we will shar

　　The so-called vertex buffer is a buffer that stores vertex data directly on the GPU and does not need to be copied from the CPU to the GPU.

In the bipartite graph, there is a problem: vertex overwrite. Figure GVertex OverwriteQ is a set of vertices that contain V (G). Q contains at least one endpoint on each edge. All vertices of Q overwrite edge set E (G ). If the overwrite of each vertex requires a different price, it can be said that it is a different cost, or a point right, the problem can be described as: when the edge is overwritten,

What is the difference between d3dfvf_xyzrhw and d3dfvf_xyz? I didn't seem to have thought carefully before. I just saw the saying in beginning directx9: The rhw value, which stands for reciprocal of homogeneous W [1], tells direct3d that the vertices that are being used are already in screen coordinates. this value is normally used in fog and clipping calculations and shocould be set to 1.0. Today, an experiment was conducted to show that if no rhw exists in the

To solve this problem, you must master the following two points: 1. minimum vertex overwrite of a bipartite graph = maximum matching of a bidirectional bipartite graph/2. 2. Using Vector in STL, you can easily create an adjacent table for graph storage. Push_back () and clear () operations are mainly used. 3. scanf () and printf () functions can easily implement the input and output in the question. For details, see the code.

The output shoshould be printed on the standard output. for each given input data set, print one integer number in a single line that gives the result (the minimum number of soldiers ). an example is given in the following table: Sample input4 0 :( 1) 1 1 :( 2) 2 3 2 :( 0) 3 :( 0) 5 3 :( 3) 1 4 2 1 :( 1) 0 2 :( 0) 0 :( 0) 4 :( 0) Sample output1 2 Sourcesoutheastern Europe 2000 Recommendjgshining is the minimum vertex overwrite of a bipa

In my recently written terrain renderingProgramIt is found that using vertex buffer cannot increase the frame rate. Using VBO can indeed increase the frame rate by at least twice, but can display lists achieve the speed of VBO? My video card is NVIDIA geforce FX 5700le, and the video card driver 81. 98. However, we found that using displaylists can save half of the video memory compared with VBO through the NVIDIA gdebugger test. I went to gamedev and

For a directed graph, given the start point and end point, ask him about the number of cut points. The cut point means that removing this point makes S and T disconnected. S and T are also cut points. First, find an arbitrary path from S to T. If there is no path, the number of cut points is N. If a path is found, mark the point in the path, first of all, it is clear that the cut point will not be on any point outside the path, because after removing the point outside, there is still the path ju

Given A point of p (x0, y0) on the plane, determine whether the point is in the Triangle ABC. The vertex coordinates of the triangle are A (xa, xb), B (xb, yb ), C (xc, yc ). You can use the area method to determine the area. The method S (A, B, C) indicates the area of the Triangle ABC.1. If abs (S (A, B, C) = abs (S (P, B, C) + abs (S (A, P, C )) + abs (S (A, B, P), P is inside or beside the Triangle ABC; if there is abs (S (P, B, C )) abs (S (A, P,

Import Determines whether the touch point is inside a polygon.Method 1. Mathematical Methods The advantage of this method is that any platform can be used, not only for AndroidAlgorithm: Solve the intersection of the horizontal line and each side of the polygon through this point. If the intersection of one side is odd, it is true. Okay, we actually need to look at the intersection of the single side ray of this point and the polygon.
