Impossible Geometry - Reutersvärd Rectangle in a Sphere

 

This Reutersvard rectangle was tough to align.
Used the blender addon by Matias to create the initial Reutersvärd rectangle and then modified it, and added lizards..

Oscar Reutersvärd (29 November 1915 – 2 February 2002) was a Swedish graphic artist, who in 1934 pioneered the art of 3D drawings that may initially appear feasible, yet cannot be physically constructed. He is sometimes described as “the father of the impossible figure” - Wikipedia

Impossible Geometry - Triple Ouroboros Penrose Triangle

 

Inspired by @matiasgarate3d ‘s art spotlight - https://sketchfab.com/blogs/community/art-spotlight-impossible-penrose-snake/

Had remembered the Ouroboros(snake eating its own tail) I’d seen in tattoos and on tv (Millenium had it in the opening titles).. anyway that sent me down a rabbit hole and I decided to do a triple headed version.

Used the blender addon by Matias to create the initial penrose triangle and then modified it.
Heres the 3d model

3d scan - Stump

A tree stump we pass on our dog walk route. Its of a tree that had been eaten up by termites. Was chopped down before it damaged powerlines.. but it actually broke in this uneven way, since it was hollowed out by the bugs.

Scanned with Scann3d but the scan failed.. so I ran the same photographs through Meshroom and got these results. Cleaned up and decimated(reduced detail) in Blender.

Quick Sculpt in Webgl

 Daily doodle in a browser app called SculptGL. Its a 3d sculpting tool that doesnt require any software to be installed.. runs on a browser. Infact this particular doodle started on my phone..and  then I used my computer to refine it a bit.

Heres the 3d file (VR and AR  enabled)
