New York City Drug Crime Map Visualizations

The data is collected by the New York Police Department. It can be found here data.cityofnewyork.us. To create the maps below, the dataset titled “NYPD Complaint Data Historic” was filtered down by the calcification of “Dangerous Drugs”. Carto was used to render maps.

Simulating Rigid Bodies interacting with Fluids using Blender

Physics animations created using Blender. Combining Rigid with Fluid.
How?
First, the rigid body simulation was created using the Blender Game Engine. Then, the simulation was recorded, so each rigid body object had its own animation. Next, in Blender’s Cycles Engine, all the animated rigid body objects were assigned either Fluid->Obstacle or Collision physics attributes. From there, another simulation was baked on top of the rigid body animation using either particle or fluid sims.

Chicago Knife Fight Maps 2010 – 2019

Mapping a collection of knife crimes in Chicago.

Date range spans from 2010 through 2019. The data comes from data.cityofchicago.org, and is collected by the Chicago Police Department (reported incidents of crime).

Reddit’s most hateful subs, or subs most hated by r/AgainstHateSubreddits

I’ve always been interested in the ever dynamic classification of hate on Reddit. As the post modernist set of moralities continues to expand, more and more subjects, ideas, and opinions become taboo. A growing creep of egg shells in Reddit’s ecosystem. One particular subreddit spearheads the outrage operations: /r/AgainstHateSubreddits.

It being a new year, I wanted to get a clearer picture of the sub’s current targets. So I wrote a quick script to parse out all subreddits names from hot post titles and created a simple wordcloud. Font size emphasis is increased by frequency of occurrence.

Double Pendulum and More Simulations

Unless the initial conditions are identical, they never swing the same.

The video below, displays a variety of chaotic blooms.

Gravity Simulations with Particle Streams

A compilation of gravity force simulations. Animations show what happens to a stream of particles when the force of gravity changes, or the source of gravity moves. These simulations were baked using Blender’s physics system.

Flower like shapes and interesting stream knots can be seen forming in the video below.

Fluid Resolution Differences in Blender 2.79

A video compilation showing how fluid behaves at different resolutions. These clips were rendered using the cycles engine in blender 2.79. Two distinct structures were created for the fluid simulations.

Close Packing Defect Formations of Equilateral Spheres

I made some animations of crystallographic defect formations using equilateral spheres. Point defects, lattice regions, and other interesting patterns can be seen forming in the video below. This was created using Blender’s rigid body physics system.
