I'd follow the LXe example in how to 'detect' photons arriving at the photocathode. For each photon I can then get the local coordinates of the photo cathode (x and y). See, for example:
You can then simply assign this information to your assumed pixels and you are done. No need to define a "read-out geometry".

I am not an expert in ROG and I have never tried using it in conjunction with optical photon detection. You may have more success getting advice on (which ever) Forum is suited for questions regarding 'read-out geometry' if you insist in learning how to get this right.
