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.

Stump Nov 2020 by Chaitanya Krishnan on Sketchfab

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)

The material is just a matcap with the curvature tweaks as below

The rest of the look is using SSAO and sharpness

Batman Tactical Flight Suit

 Did this sculpt on #Batmanday 
Inspired by mempo masks.. gave batman's mask(usually just a cowl) a tactical and aesthetic update.

You can see the full 3d sculpt (slightly optimised model) below.

Cybernetic Trapeze Artist

Started working on my second character and other elements…

1) Sculpted reptillian cybernetically enhanced character(will add more details later)
2) Currently sculpting the multi armed cyborg character..

ToDo:
Trapeze hover drone things.. and other arial objects..

A trapeze act in a futuristic and alien circus. Work In Progress, not final

Scifi Circus Trapeze

(Work In Progress)

Taking part in the SciFi Circus character Sculpting challenge at Sketchfab. It has some awesome prizes, but also I love the theme this month! Check it out here.

I did a rough blockout of the scene and composition.. now doing some sculpting.
The model can be viewed here:

Have a few weeks to work on this in my free time. You can view recordings of the sculpting sessions at my youtube channel or this playlist.

Comprehensive Geologic Map of the Moon

Have you ever wondered what kind of rocks make up those bright and dark splotches on the moon? Well, the USGS has just released a new authoritative map to help explain the 4.5-billion-year-old history of our nearest neighbor in space. Read all about it at https://www.usgs.gov/news/usgs-releases-first-ever-comprehensive-geologic-map-moon

Anyway heres my 3d version incorporating the maps available at the above link.
Made with Blender and displayed in Sketchfab

   
   

        Comprehensive Geologic Map of the Moon

Below is a key to the color coding on the surface:

For the first time, the entire lunar surface has been completely mapped and uniformly classified by scientists from the USGS Astrogeology Science Center, in collaboration with NASA and the Lunar Planetary Institute.

The lunar map, called the “Unified Geologic Map of the Moon,” will serve as the definitive blueprint of the moon’s surface geology for future human missions and will be invaluable for the international scientific community, educators and the public-at-large. The digital map is available online now and shows the moon’s geology in incredible detail (1:5,000,000 scale).

Winged Hound Polygon Style

Modelled and animated in Blender. Rendered with cycles.

Hainu are winged dogs. They are strong, fast, and ferocious, and can be as menacing to humans as wolves. … According to the first story, recorded in the Chikugo Kokorogashi in 1777, the winged dog was a ferocious creature which attacked humans and livestock.

Japanese name: 羽犬 Romanized name: Hainu

Rigged and animated version of an older Daily Doodle with Blender.. see the original here - https://sketchfab.com/3d-models/winged-dogs-dfc4e6eb25d04bff9ec780f4c3cb3f4e

Heres the AR and VR viewable model:

Sculptjanuary 2020

I did finish Sculptjanuary last month, but didnt have the time to write about it, so here goes. The topics in the prompt list were quite good, however I was busy with a family emergency and couldn't give it all i could. Still heres the full set:

To truely appreciate them check them out in 3d (also VR and AR enabled) at https://sketchfab.com/chaitanyak/collections/sculpt-january-2020

Let me know if you would like to see me print any of these, or refine and put them up on shapeways.
