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.

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.

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.

Map of Chicago created by Traffic Crashes 2016 – 2018

Point and heat maps of Chicago created by plotting coordinates of traffic crashes. Time range used, spans from January 2016 through September 2018. The data can be found at data.cityofchicago.org.

Crash data shows information about each traffic crash on city streets within the City of Chicago limits and under the jurisdiction of Chicago Police Department (CPD).
