Dam Repair




An old project from last year got resurrected briefly.
Heres the post from back then.

We were commissioned to build a diorama of a dam and floodplain for an exhibition.
It now needs to be setup at Atree's campus. So we went over and took stock of the diorama, its plumbing and electronics..
I need to go back tomorrow and do some water proofing.

Scull Scan


Was out with the dogs, when they discovered this canine skull.. The lighting was just right for 3d scanning (overcast, no strong shadows) so I took out my phone and got clicking.

32 photos later, we headed home and I put them through a free tool called Meshroom  and then took the result to Blender for some minimal cleanup and mesh simplification using the Decimate modifier.



Here's the result -



I need to remember to take more closeups.. in this case you can see that the canines didnt scan right.. also need to take a few more pics of the interesting surroundings.

Steampunk Airbus


My main broadband connection has been down for months, so streaming has not been possible in a while. Anyway I decided to get back to my mid night daily doodles regardless of wether I can stream the process or not.


Heres the latest product of one such session-





A concept .. sort of steampunk.. flying bus.

Inspired/adapted from this amazing (and much more detailed) art by Concept Artist Braydan Barrett 

Heres a timelapse of the initial modelling session

Undead Cat ABS Print

Had sculpted this undead cat a while back,

Here are the first prints via shapeways


I love shapeways, their quality and range of material options is unrivalled.. but
- their shipping costs sometimes cost more than the cost of the print, and
- the shipments take 2-3weeks to get to my part of the world.

So I got my maker buddy Vincent to see if these files can be printed on one of the printers he has.. heres the first print in ABS from a Prusa -


There are some visible issues with splitting etc.. but the detail is astounding!
I'm very impressed. Took around 6+ hrs with 10% infill.


Here it is after all the cracks glued back and some copper hand painted details

and here it is next to the old shapeways print



If your interested in the original sculpt,
- You can see the making of video here  
- You can view it in 3d here and if you have a printer, you may download the file and have at it.
- If you don't have a printer, you can order a print via shapeways here

War Paint




Done entirely in blender.
Materials and lighting with Sketchfab.




Here are some screen grabs from the process...
Sculpting in Blender is so much fun these days, now that I've unlearned some of my Zbrush workflow..

Texture painting with bpainter(beta addon with more brushes) is a load of fun!



Winged Creature

Daily doodle.. experiment going back and forth from zbrush to blender and then back to zbrusn.
Modelled with zpheres in zbrushcore and some modelling in blender(wing membrane). Finally taken back to be sculpted in zbrush core

Vitruvian Creature



The Vitruvian Man, or simply L'Uomo Vitruviano, is a drawing by the Italian polymath Leonardo da Vinci around 1490. It is accompanied by notes based on the work of the architect Vitruvius.


Image result for vitruvian man

The drawing, which is in pen and ink on paper, depicts a man in two superimposed positions with his arms and legs apart and inscribed in a circle and square. The drawing and text are sometimes called the Canon of Proportions or, less often, Proportions of Man.The drawing is based on the correlations of ideal human proportions with geometry described by the ancient Roman architect Vitruvius in Book III of his treatise De architectura. Vitruvius described the human figure as being the principal source of proportion among the classical orders of architecture. Vitruvius determined that the ideal body should be eight heads high. Leonardo's drawing is traditionally named in honor of the architect. - Learn more about it at Wikipedia

Here's one of my daily doodles of a creature inspired by it.


I sort of went with it.. and worked on it for a few more nights.
Heres a composition with multiple posed ones..
Its amazing that with websites like Sketchfab, one can create real time graphics that look as good as still renders from just a few years back. Complete with Depth of Field, Subsurface Scattering and beautiful lighting. After modelling it in Blender I went straight to sketchfab to work out the materials and lighting!


...

And heres the final "hatchling".

Mouse Keyboard Headset Combo


Ordered this combo set for my new  work computer - Redgear Manta Redgear MT41
It arrived a few days before my desktop arrives, so am using it with my laptop..

Was skeptical about the membrane keys but on using it(after years of laptop keyboards and cheap budget keyboards), its just so good!
Cant imagine going back to the laptop's keyboard now!

The included mousepad is really luxuriously good!


Changing colors:
Keyboard:
- Pressing the ScrLk key changes the color
- Pressing the Fn key and ScrLk key lets you turn on breath mode(it cycles through the 3 colors.
  I havnt figured out how to make it breath just one color)
- Pressing ScrlLk key during breath mode will just switch back to static mode.

Mouse:
-Out of the box its  been programmed to have a certain color set to certain dpi so if you use the -+  buttons to change dpi it will also change color.
-If you install the software on the cd you can do advanced modifications.i haven't fully explored it    yet(have not found a single color breath option).. see the screenshots of the interface.

Headset:
- As far as I can tell there is no way to control the lights.. nor do they react  to music etc.
- The lights are sometimes not the same on either side
- Disconnecting the usb plug switches it off. some might prefer that.

Cons:
- Not a fan of the narrow Enter key.

- Mouse software was on a cd.. and I had no cd drive on my machines.. the website had no download    section. Luckily my friend had an external cd drive sitting around.anyway heres a download link if you need it.
- Headset lights are  weird
- No white light option in either the keyboard, mouse or headset

Pros:
- Low cost. lets be frank, i'd love  to get in on the cherry key setups.. but who has the cash for that? not me.
- Just the keyboard and mouse combo actually cost more.. so this deal is a real steal.. while it lasts.
- The included mousepad is really luxuriously good!
- Finish and build quality are really good.. total value for money.
Get this combo here: https://amzn.to/2x4J4lY

Projection Mapping in Odisha


Did a last minute rush job on a projection mapping assignment in the city of Cuttak in Odisha..
Here are some bits and pieces of it.. more documentation to follow.

I had a couple of days to generate graphics for a 30min show.. so decided to bring my home computer along.. that way I could work on one while I rendered on the other..
 


This is how you travel with a gaming/3d modelling rig!

and this is how you set up a nerve center in the hotel room.

Here are some glimpses of the projection mapping during rehearsals




Big Red Mech

A quick blocking out exercise of a big red mech..

A Spider Man

Not your usual wall crawler this.


Spider Man by Chaitanya Krishnan on Sketchfab

Modelled with Zspheres. 
Sculpted and painted in Zbrush Core



Undead Jet

Another daily doodle.. of an undead aircraft.



You can follow along here:
Started it off in Blender.. 
and finished it in zbrushCore 

Daily Doodle Cybernetic Dinosaur

The title is pretty self explanatory :D



Heres the work in progress.. you can hit the speed options and watch it as a timelapse/hyperspeed video
