 We know that the arguments (x,y) of get_sample represent number between 0, 1. It is not fully clear for me in which pixel (i,j) of the input image they mapp into. is this given by i = x * OUTPUT_WIDTH and j = y * OUTPUT_HEIGHT?

Any help with this?

Have someone writen some function that will transform (x,y) into some polar coords?

 The offset you might be looking for could be 1 / SIZE?
