What would be the recommended way to display this image in a graphics view?
We have no idea what your three-dimensional integer array data represents or what a logical way to display it would be. How does a 3d array represent image data? Is it a stack of multiple images?
I am currently using a nested loop to loop through the entire array and "QImage::setPixel(x,y,Qrgb)" to set every the color of every pixel.
Where do x, y, and the arguments for the colour come from in the three-dimensional array?
