I am a new user of rtk, and I have some questions regarding the FirstReconstruction example given in github. I have generated an image as attached, with 4 tiny ball-like drawing hanging from the top. Can anyone explain to me why do I get such image and what
are the implications of constantImageSource, rei, constantImageSource2, feldkamp and fieldofview?</div>
