I walk around with my recorder apps and collect data from the world around me.
I visualize the datasets in Houdini.
I wrote a couple of apps for my Pixel phone to record lots of data from the many sensors found on the device, using ARCore and other computer vision algorithms.
I wrote tools to import and manipulate the datasets into Houdini (but this can easily be extended to other 2D and 3D visualization softwares).
Once I parse the data in Houdini, I start exploring the patterns I see and imagine ways to create and visualize the procedural geometry found in such datasets.
