Update: Moving Website to AWS

Posted on

I’m currently moving hosting providers from Hostgator to AWS, so sorry if the site has gone down over the last week! I think everything is up except https which I should get fixed in the next week. In the spirit of this blog, I might as well comment on the moving process. I moved from […]

Update: ECS and New Posts

Posted on

Whew summer is over. I ended up being even busier over the summer than last spring. I’m working on a startup, which is fast-paced and rewarding, but it really is a time black hole (things a physicist wouldn’t say for $100). I worked on the project some over the summer, but when my hours devoted […]

Update: Unity

Posted on

As I stated in my last post, I don’t have much time to work on this project right now. However I’m still working on it some. I’ve been porting it to Unity so I don’t have to worry about rendering. The above is a low-res pure noise map. Why did I switch to Unity? I […]

It’s been a month since my last post and (surprisingly) some people have actually messaged me asking when the next post will be. Unfortunately, I’m going to be very busy from now until May (in part learning stuff that will help with this project). The good news is I am very committed to this project […]

Climate 3: Insolation and Black-Body Radiation

Posted on

The only way for energy to enter or leave my climate simulation is through radiation. As is discussed more formally below, energy enters via solar radiation, and energy leaves via black-body radiation. I’m starting with this because these two phenomena drive the entire climate system. Without them, winds and weather can’t exist. With only radiation, […]

Climate 2: Rivers and Erosion

Posted on

I’m doing this a little out of order. Why groundwater and erosion first? Modeling the water layer on and in the ground is an isolated section of climate simulation. Whereas the air modeling has interdependent parts (radiation, convection, etc.), the groundwater system is self-contained except for precipitation and evaporation. I can easily implement a dummy […]

Climate 1: Climate Simulation for the Computationally Limited (Research and Overview)

Posted on

Unlike plate tectonics, computational climate simulation has an enormous body of research because of modern meteorology. Although we often we joke about incorrect weather forecasts, it’s pretty amazing how accurately we can model the entire atmosphere days in advance.  With climate simulation we have the opposite problem. Modern Global Climate Models are so detailed that it’s […]

Update: Climate Sim Stability

Posted on

This week I encountered an interesting simulation stability bug in my climate. All the air in my simulation was steadily traveling from low to high altitude. I haven’t posted on my climate simulation section yet so here’s a little background on how it works. I hope it’s enough to help this post make sense. My […]

Terrain Generation 5: Fault Features

Posted on

In my last post, I worked on making tectonic plates and smooth elevation transitions between plates, coasts, continents, and continental shelves. In this post, I’ll add additional fault features such as mountains and rifts. Also if you’re puzzled by any of my not-very-scientific plate tectonics, check out my post on Tectonic Plates. Table of Contents Fault […]
