The objects were generated by Incendia_NEXT, converted to a 3D object in Geometrica, cleaned up in MeshLab and smoothed in Bryce. As material blueish diffuse, PHT boosted specular, partly reflecting. Light and reflections by the WpH76_SC250 HDRI from the Hyper Textures Base set (available at Daz 3D). Ground and wall by the Seamless Background by Art Wade; transparent and reflecting with bump. Two antagonal objects.
