The arches were modeled in Bryce and assembled to an arena. Around it a tilted mirror cube. Lit by the esoSky HDRI, made from a picture of the full Milkyway galaxy (Credits ESO/S. Brunier) from inside and outside as backdrop, a distant light and the sun. In front of the camera the EWL (extreme wide-angle fisheye lens) from Lenses & Filters (available at Daz 3D), horizontal angle of view 275Â°. An arena in a multidimensional space.
