I’m in the process of optimizing some old prototype line rendering code. This code isn’t broken, but on every frame, it creates many line geometry objects, renders them once, and throws them away, never to be used again. Then it creates more line objects on the next time–repeat. Allocating memory all of the time like

As a continuation to my last post, I have been working from time to time on the character I had mentioned there. So, I guess I’ll talk a little bit more about my workflow as of recently. I was using Zbrush to not only texture the character, but also to unwrap its UVs using Zbrush’s

Happy Halloween from the FRL! To celebrate, I thought it would be fun to talk about masks and avatars in the virtual world. I’ve always found the idea of choosing your appearance to be interesting. In online games and forums, people have been choosing avatars to represent themselves for decades. Sometimes, people will attempt to

Those were the days where people interacted with simple visual or textual ads. Now, we walk by them on the subway and on the streets without a second glance. Our generation has became immune to much of the visual noise and over stimulation around us. So, many companies are beginning to use Virtual Reality to

One of the things I like most about studying a new topic is learning about the tools used by practitioners in that field. Through my process of implementing computer vision / deep learning research papers, I became aware of the Python Pandas module that is widely used by data scientists. When used within a Jupyter

A couple weeks back during one of our research meetings, Ken asked everyone to imagine what a world without screens could be like and to prototype them at the lab. It’s a question I’ve been fascinated with and curious to see what path we actually end up taking to get there. I figured I’d share

This week, I began learning a little bit of Cinema 4D. It’s another 3D modeling software known mostly for its motion graphics suite. I took 2 -3 days to learn the basics of modeling and UV mapping in Cinema 4D. I made a piggy bank.               As someone who

I talked about collision avoidance by using Unity NavMesh in my last post. The result is great if you have an agent who needs to avoid all the obstacles no matter when they move or stay stationary. The NavMesh agent module in Unity takes care of the pathfinding, and the obstacle module defines what objects

UIST 2018 was just held in Germany a week ago. I am curious that how it is like this year so I was planning to go through it quickly at the beginning. First, I found out there was still quite a lot of work related to handmade new devices and robotics. The wearable shape-proxy interface, PuPoP, looks
