VVVV at a Workshop with Jonathan OHear

In Nov 2022, I attended a workshop with Jonathan OHear at Attakalari. This was an interesting workshop for me, as it had been a long time since I had sat down to learn something new. In this case something entirely outside my comfort zone - VVVV 

On each day Jonathan introduced us to byte sized concepts in lighting and coding, in what I as an educator, found was a well thought out and manageable lesson plan. 

We learnt how to program an ESP32 variant that had wifi and bluetooth as well as a battery pack(added by the support team Transmedia at Attakalri)

The workshop culminated in a show where we showcased our projects for the public.

This was pretty much my first time doing any electronics in over a decade, was pleasantly surprised with how simple things had gotten. 
We learnt to control DMX lights as well as LEDs and use sensor inputs from everything  from motion sensors to brain scanning devices.

I however opted to use a webcam(modified for infrared) to track a person's movement and use that to manipulate a 3d model that would generate particles, based on the movement.
Heres what that looked like:

Unfortunately I dont have any pictures or footage from the final day, but it was pretty much what you see above. The 3d model I used as the base object that would be the emitter of particles, was a 3d scan of my desk at SMI.

This is the patch I eventually had.. 

heres a primer:

For anyone who may need this in future heres the setup I got working - DOWNLOAD
Have added a dampner to delay/soften the movement and color transitions.
Used the mesh from a 3d scan of my office desk as the emitter.

Heres a forum thread that was a big help to me.

On the last day we put on a little show for the public, allowing them to witness and interact with our creations.

This is the happy group on day 1 - 
Hope to run into them again!

Found the time to quickly doodle this for the weekly art challenge.

Modelled in Blender. Hex textures done in Inkscape.

Cyberpunk Catbed

Did a scan of our cat Pinku the other day while she was fast asleep.
This is what I did with that scan

The original scan had some bugs because the lighting was suboptimal, so large chunks were missing.

I took it to Blender to explore some repair techniques, but woundup building this contraption around it.

Heres the finished model..

You can also try it in AR with Snapchat -

You can also try it in Instagram with this code:

Heres a video of the process I followed to use the 3d scan of my cat in the model. It covers cleanup and using the decimate modifier to optimise the geometry.

Voxel Batman

 Made a quick model for Batman Day 2022
(cheated the traditional voxel process, by using the Remesh Modifier in Blender)

Heres a timelapse of the process. Scroll down for the normal speed video.

Heres the 3d Model

The video below is of the entire session from start to finish.

Kracken Lens


Dug out this model from an old speed modelling session.
Turned it into a snapchat lens.

Greasepencil to Sketchfab - Pagoda of the crystal relic

Decided to revisit working with grease pencil and tried to find a way to upload it on sketchfab.
heres a video of the greasepencil version and the version I got working in sketchfab.

Heres the model up at Sketchfab

Pagoda of the crystal relic by Chaitanya Krishnan on Sketchfab

The process I followed involved 3 steps

1) Converting the greasepencil object to a path

2) Adding some thickness…

3) Converting this to mesh

if the mesh is too dense(most likely) use the Decimate modifier to optimize it

This gives you all the paths converted to usable thick meshes… which works in Sketchfab.

Now I need to figure out how to get fills and brush styles(if even possible).

Synthetic Human in Lab


Built this for a client last year. Its a small part of the final video.
The suit, hair and vfx were created in Blender by myself and Parag Gupta. We used Blender primarily, and Adobe After Effects for the final composites.

The character was created using Makehuman - http://www.makehumancommunity.org/
The lab was from this scene over at Sketchfab - https://sketchfab.com/3d-models/secret-laboratory-blocking-b5c3ebc5da774f86a794d9e18db6c2e7 by rhinohopper

Old Crone Gator

Heres the old crone gator I was working on. Started with an exploration of techniques in Blender, ranging from box modelling, using the skin modifier, and finally some minor sculpting.

This is the doodle it started as

Here are some more stills rendered out of sketchfab using their lab tools.

And heres the sketchfab model itself

Will rig it some day. but first want to try a print

Meanwhile heres a stylised toon shaded version

Psyche - Change My Mind 2022

Earlier this year I participated in an event that was a collaborative experience with art-scientist Andrew Carnie. Along with other artists we worked on sculptural entries that made up the exhibit Change My Mind, which deals with the mind and its potential alteration using implanted devices.

As an emerging media artist myself who works with VR, AR, Projection mapping as well as other technology and techniques, it was refreshing to get back to working with paper!

Heres what it was about, for me.

Changes in my life over the past couple of years have brought about an upheaval in my personal and professional life. It has meant a combination of me coming to terms with my situation and relationships as well as old unaddressed issues.  As a means of adapting and better equipping myself, I’ve been exploring my mental health and looking into habit breaking exercises for my well being.  There is no shortcut for such development or therapy today. 

Perhaps one day an implant could facilitate this kind of growth and recalibration.

This work is an attempt to visualise this process, where an implant would rip out undesirable parts of one's personality or behaviour, while nurturing and enabling other underdeveloped ones.

My first thought was to create something in Virtual Reality or Artificial Reality, my current artistic medium, to depict an implant that could hack into digital devices, networks, blockchains.

However, upon introspection over the last few weeks, on my own exploration of my mind, I decided to try a different approach, embracing an old familiar technique to evoke a fantastical technological breakthrough of sorts. 

For this piece I have used paper carving and sculptural techniques. I used to love this medium almost two decades ago. Lately I have been revisiting positive things from my past, and so decided to revisit this medium for the project. 

You can watch the video session that it culminated with below:

The event was facilitated by Science Gallery Bengaluru.
