I am currently creating my own 3D renderer (think something like OpenGL). As a first step, I created a mini program below to render primitive 2D shapes essential to 3D graphics: points, lines, and triangles with z buffering. I'm hoping for code review on three essential methods in the class Displ...

I wrote a rudimentary implementation of doubly linked list. Feel free to comment anything! #ifndef __CLRS4_LINKED_LIST_H__ #define __CLRS4_LINKED_LIST_H__ #include <common.h> #include <concepts> #include <iterator> namespace frozenca::hard { using namespace std; template <typename T> class Li...

I am trying to understand the following code from Matlab: numElements = sizes(ii)/sizeOfDouble; hostData = randi([0 9], numElements, 1); gpuData = randi([0 9], numElements, 1, 'gpuArray'); % Time sending to GPU sendFcn = @() gpuArray(hostData); sendTimes(ii) = gputimeit(sendFcn); % Time gathering...

I am writing a code that generates a URL and attempts to perform a web scraping upon the resulting website. However, since there's too many variables to take into account, I did something like this: try { const url = StarCityController.getSearchURLForCard( card...
