I don’t have much experience with vectors and for this problem I need to be able to read in a txt file that contains a grid that looks like this: I know that I want to put it into a vector of vectors so I have written this so far vector<vector<char> > map; I am ..

I am currently trying to draw a 2D grid on a single quad using only shaders. I am using SFML as the graphics library and sf::View to control the camera. So far I have been able to draw an anti-aliased multi level grid. The first level (blue) outlines a chunk and the second level (grey) ..

Im trying to upsample my image. I fill the upsampled version with corresponding pixels in this way. pseudocode: upsampled.getPixel(((int)(x * factorX), (int)(y * factorY))) = old.getPixel(x, y) as a result i end up with the bitmap that is not completely filled and I try to fill each not filled pixel with it’s nearest filled neighbor. ..

I need to make a gird in c++. I have some points in 2-D space like (x,y). In my program I need to create a grid which each points should be in this grid based on its (x,y). and then I have to divide this grid to boxed with height and width of R (radius) ..

What is the problem in this? When i print the matrix in main function it work fine. But when i pass it in function and print their it gives me "invalid type argument of unary ‘*’ (have ‘int’)". The program is.. #include<bits/stdc++.h> #define ll long long int #define endl "n" #define loop(i,a,b) for(int i=a;i<=b;i++) #define ..

I am thinking of coding a layout manager to create desktop UI in C++ so I wonder if anyone knows or has experience in these topics, what is the best approach for a grid/table layout? I have been playing around with QT, GTK, wxwidgets and they all have different approaches in their grid/table layouts. for ..

I have created my own simple version of the Matlab inbuilt Meshgrid function for my research project using the following code int N = 10000 //note that I want this to be a huge array double *X= new double[N*N]; double *Y= new double[N*N]; for(int j = 1;j<=N;j++) { for(int i = 0;i<=N-1;i++) { X[j*N+i] = ..

I really stuck on writing Tip Calculator program, I did this program so many ways but still there is a mistake, and I can’t even click to start the program Could you please help me ? I am trying to set upt the calculate button but don’t know if it’s right and how to set ..

Basically I’m drawing a grid with 250k tiles. If I draw in a loop this grid the memory stays at 120mb but if I translate the coordinates of each tile with an offset, as soon as the grid starts to get drawn outside of the window viewport, then the memory grows and grows every frame ..

I need to fix the code that generates the grid. It should fit in the graphics window. My current is also drawn outside the graphics window and it is not always a regular grid. std::vector<QPoint> Draw::grid(int n, int height){ std::vector<QPoint> points; double a = rand()%100; double b = rand()%100; int size = sqrt(n); points.push_back(QPoint(10,10)); for(int ..
