Modified Menger Sponge

    Newer Older

    A "Level 2" Menger sponge. I purposely subdivided the blocks of the sponge to slightly less than 1/3 (3/10 instead of 3/9) to create the gaps between sub-blocks.

    The recursion was purposely stopped at 3 iterations (yes, a "Level 2") to keep the object count down. This image has 8,000 objects (20^3), but at 4 iterations, that balloons to 160,000 objects!

    Modeled in Structure Synth and rendered in sunflow. I'm also trying a different lighting model in sunflow for this one to cast even more photo-realistic lighting [a spherical light source, plus ambient occlusion global illumination, with diffuse shaders for the object and the ground plane].

      Very nice lighting

      @subblue: yeah, I wasn't so thrilled with the default lighting setup created by the structure synth exporter, so I manually edited a new lighting and shader setup. I'm really impressed with how capable sunflow is as a renderer.

      Nice, why don't you post a 3d version of this as well? :D

      Hey it is "Sponge Box Square Points"

      I've recently tried to load some of my 3D models, maybe you could save your model to a format that site could import so people could play with the object in realtime 3D.

      This version of the menger sponge looks like a block of flats.

      This kind of sponge gets very popular - will do one of these tomorrow.
