simple_diffraction_with_gpu.cpp

This code is to calculate diffraction using the angular spectrum method on a GPU.

#include "cwo.h"
#include "gwo.h"

int main()
{
        CWO a;
        GWO g;
        a.Load("sample.bmp"); //Load image file 
        g.Send(a);
        g.Diffract(0.1, CWO_ANGULAR); //Calculate diffraction from the image using the angular spectrum method
        g.Intensity(); //Calculate the light intensity from the diffracted result
        g.Scale(255); // Convert the intensity to 255-steps data
        g.Recv(a);
        a.Save("diffract.bmp"); //Save the intensity as bitmap file
}
