Sam Johnson

Game Developer

"What I cannot create, I do not understand."

-Richard Feynman

Hi! My name is Sam. I'm a programmer and an indie game developer.

I want to work for you! I currently live in Boulder, Colorado, but I am willing to relocate.

Portfolio

I'm working on a fantasy action RPG called Shattered Lords. It's about uncovering the mysteries of a long dead crystal kingdom, overcoming madness, and surviving in the face of all odds. Check out the latest development video:

I built its engine from scratch, with Java and OpenGL. I also did all the animation and modeling myself, in Blender.

Over the past few years, I've written a very complete game library in Java. It forms the backbone of Shattered Lords; and handles math, physics, animation, model loading, sound, window creation, and more. It's open source!

Skills

Having built my own engine, I have a thorough understanding of game programming. I've written systems ranging from collision detection to skeletal animation; optimized and tested them; and weaved them together into a cohesive, modular whole.

My language of choice is Java; but I know C++, Python, Javascript, and Lua; and I'm always willing to learn.

I have a passion for, and deep familiarity with graphics hardware and APIs, especially OpenGL. I'm obsessed with physically based rendering. For the ultra nerdy, here's a list of each graphics algorithm I personally implemented, just for Shattered Lords.

  • Cascaded Shadow Maps
  • Horizon-Based Ambient Occlusion
  • Anamorphic Bloom
  • Screen-Space Reflections
  • Reconstruction Motion Blur
  • Dithering
  • Tonemapping
  • Fast Approximate Anti-Aliasing

I routinely write development tools to make it possible to create games. Whether the need is rendering cubemaps, computing bounding volume hierarchies, or converting assets; I'll make it automatic and convenient.

Also, I love version control, and use it religiously—I use Git, and I've used Mercurial and SVN before.

So often, games are all about simulation! In that vein, I am well versed in physics, optics, and more. Perhaps my astronomy knowledge could beef up your space game. Maybe you need a realistic model of atmospheric scattering... for your space game! Or maybe some special relativity will give you that edge in the highly competitive SPACE GAME market. I LIKE SPACE.

The flip side of science is math. I have extensive knowledge in linear algebra, numerical analysis, geometry, and a dash of calculus.

I can set your world in motion. I have tons of practice making game animations in Blender. I've also used 3ds Max. My technical knowledge complements this skill nicely. I can make the animations; write the tools to convert and process them; and write the engine that blends, plays, and renders them.

I made this website! Good design makes me very happy, and this passion rounds me out as a developer. I'm very experienced with Photoshop, HTML5, and CSS. Programmer art doesn't always have to be bad!

Personality

I will not stop until it works. At the end of the day, this is the quality you're really looking for. When it matters, I am someone who does not give up. Ever.


I will learn whatever it takes. That includes new languages, APIs, tools, or even entire crafts. I will consistently go outside my comfort zone in order to deliver results.


I will treat my work as art. I won't take shortcuts because I'm a perfectionist. This isn't always a good thing—sometimes I keep working on something when others would rightfully call it finished. Of course, quality takes time.
