Portfolio of Recent Work

Drain Defense

January 2023 - May 2023

A finished prototype of a fluid based tower defense game. Playable here.

• Led small team to develop idea and assets. Taught various team member how to use git and gitlab.
• Features custom AStar pathing for water, debris avoidance, stairs, and 2d water and land connections.
  
• Fluid flowmap for velocity and real flowing fluid simulation. My custom implementation resolves the flowmap for floating bodies each time the terrain is edited.
• Custom GLSL shaders for object and river waves.

Normord

September 2022 - Present

Small team consisting of myself (lead programmer) and a 3D artist to create a indie single player horror shooter.

• Implemented enemy AI and navigation, weaponry, AI threat analysis, and player controller.
• Relied heavily on linear algebra.
• Led team to adopt git, gitlab, and figma.

Not Boring Content

August 2022 - November 2022

3D teaching tool to help teach programming using the Godot game engine.

• For more usage examples see github link here.
• Used to teach pre-teens fundamentals of programming.

Stactory

September 2021 to August 2022

3D Factory themed physics based puzzle game using the Godot game engine.

• Maximized number of rigid bodies present in the simulation.
•  3D models in blender (really enjoyed learning UV mapping)
• Unfortunately later learned that Godot was not the right engine for this type of game.
• Very early demo still online here.

Orometric Noise for Procedural Terrain Generation

June 2021 - March 2022

Novel solution to procedural terrain using Orometry and a modified cellular noise function.

• Published research and gave dissertation using standard Chinese (fun).
• Became one of very few Americans to get a CS Masters from Sichuan University.
• As you can tell from more recent work, I was wrong in my thinking that "I'd better study terrain gen, after all any game I want to create later will definitely need 3d terrain!"
• Became familiar with procedural terrain method techniques both real time and not.

Bookshelf

March 2018 to September 2019

Created digital bookshelf for children's books using webdesign tools and java backend.

• Became fluent in old-school tools: Glassfish, Netbeans, JSP, mySQL, and more for web development.
• Enjoyed learning how to use Allibaba's web tools for domain names and CDN renting.
• Performed the miracle of successfully setting up Glassfish with HTTPS certificates.
