Exoplanet art generated using Apophysis 2.08 3D Hack. The planet was generated using duplicate bubble transforms with slightly different x and y transform values. This variation in transform values led to slightly different overlayed reflections on the planet. Smaller bubble transforms were used to create the moons. The atmosphere itself was a rotation of the 3D double spiral generated previously. The rotation was done by adding a high value (0.9) of pre_rotate_x to the final transform (+FX). (In other words, the 3D double spiral was rotated almost 90 degrees and the planet was placed in the center of it.)
Finally, Xaos settings were used to manipulate texture and space by fine-tuning interactions between individual transforms (i.e. adjusting weight modifiers to/from transforms).
