we'll choose TheDXGI_FORMAT_B8G8R8A8_UNORMbecause it's compatible with Direct2D. We'll turn off display scaling, multisampling, and stereo rendering because they aren't used in this example. Since we are running directly in a CoreWindow we can leave the width and height set to 0 and ...
I usually have to deal with large 2D arrays. Before using them, I need to reset all the value to 0: 1 2 double* arr= (double*) malloc(height*width*sizeof(double));for(inti=0; i<height*width; i++) {arr[i]= 0;} However, this loop is time-consuming. I notice that in Relea...
