A long time ago...
Before engineering, I was starting my journey into general CGI, game development and human-computer interaction.
Prototyping:
Invention: Pinch/Grab (2011-2013)
It might sound controversial, but it’s true: I am one of the inventors of the pinch/grab gesture as it is known today—the de facto standard for VR and AR hand interaction.
​
This work was done while I was at Softkinetic Systems (2011-2013), now Sony DepthSensing Solutions. At that time, AR and VR hand gesture recognition didn’t exist. Although gesture recognition had been researched for decades, our prototypes were specifically developed for depth and RGBD cameras. It turns out, these gestures are a perfect fit for XR
This is not really gesture recognition, however, it is a prototype for interaction using controllers
Game Development
Challenge Your Fears, (2010)
"Challenge Your Fears" Is an adgame for Head and Gatorade developed in 2010 in a small (one-man) indie game studio (floatbox Studios Ltda.) while living in Brazil.
In those days, games for cell phones were not so widespread as today, so the target platform was browser, and it had to be light and optimized to run on most PCs...
It's a mix between a shooter and tennis game. It was quite fun to develop this!
Some of the development process:
More game prototyping:
First-person shooter (2010)
I started a small experiment on FPS game at the time. Even for Unity3D, in those days it was not so easy and required some work-arounds.. here and there. unfortunately I did not move forward with this project.
CGI
Disclaimer: For most of the videos, the resolution kinda sucks I know. These are quite old stuff, maybe someday I try to re-upload everything in higher resolution.
Intro Video: Maya Hardware Particle Rendering (2009)
​It was so fun doing this, it ran (rendered) almost in real-time, compared to software rendering, which would take forever...
Vehicle design concept: Using cloth simulation (2006)

Camera matching/tracking
Homage to Escher (2005)
This was a recorded with a Sony Minidv Hand camera, a first experiment with camera matching (tracking) and composing animation.
It was my first contact with camera tracking and localization: in order to match the real camera motion of the hand-held camera using tracked image features. I did not really imagine that 20 years later I would be writing my own localization and mapping solution.
