Experience
Procedural Planet Renderer
https://www.dropbox.com/s/sh4owe3wlgq7469/planet.zip?dl=0Developed a procedural planet renderer from scratch. It was made for the T3 Entertainment company and completed in two years. I used the following technologies: Direct X9, GPGPU, real-time ambient occlusion, Planet Mesh LOD with up to 81 times zoom-in, and physically accurate atmosphere scattering.
Tachyon Wars
An online space strategy game with AI developed as a personal project. I created this game independently, including the server and client code, half of the 2D/3D art, all shaders, sounds, database, and more. Some art and music were outsourced.
Casual Spider Solitaire
