Platformer

Source code on Github

A remake of the first level of the delightful 1990 Gamebody platformer Gargoyle's Quest.

Features

Implemented in Rust, using just wgpu for the display stack, as a learning experience.
Gamepad support, via gil-rs
Full audio
Post processing to provide pixellated Gameboy-esque LCD graphics effects

Marching Cubes

Source code on Github

An experiment with multithreaded marching cubes which degenerated, as should have been expected, into an LV-426 simulator.

Features

Multithreaded marching cubes tesselator, using an octree space subdivision to reduce the space to march
Simple OpenGL renderer, from first principles, no libraries or engines here
Several volume primitive types, up to an infinite paging terrain with automatic spatially stable random greebling system
Simple post processing stack, used for procedural sky and volumetric noise-based raymarched fog

Realtime multi-body tracking in VR

Work done at Vulcan, Inc to create realtime physical embodyment in VR, using multiple Intel RealSense depth cameras.

Features

16 Intel RealSense depth cameras, with automatic extrinsics computed via computer-vision by observing a Steam Vive Tracker with an attached aruco.
Each depth camera had a dedicated Intel NUC running human body pose tracking software, and the poses were transformed to world space and sent to a pose aggregating server
The pose aggregating server spatio/temporally tracked humans in the room and computed the best pose skeletons for each through analysis of the 16 pose streams
All this was presented in real-time to users wearing a SteamVR headset, allowing users to see one another in the room and interact.

Surfacer

Source code on Github

A 2d side-scrolling physics-based game which I never finished. It no longer even compiles, because it depends on pre-C++0x11 tr1 libraries. I plan on attacking it and getting it running again, because it's too neat to let succomb to bitrot.

Features

Destructible terrain, where cut-off geometry is dynamic, and part of gameplay
Soft-body monsters! Grubs! Jellies! Worms! Grippy tentacles! Gross stuff!
Fluids
Quaint fullscreen shader effects
SVG-based geometry representation of monsters, game items, and player, allowing me to design them in Illustrator

SGF / SRE

SimpleGameFramework & SimpleRenderingEngine: 3D Game framework written between 2007 and 2010. Written from ground-up ( as-in, I started with an empty project, and wrote it all myself) in C++ and some ObjectiveC, and with rendering in OpenGL/GLSL.

Features

Physics, using the OpenDynamicsEngine and Bullet, as pluggable modules
Shadow mapping for directional (using CSM), point and spot lights (using depth cubemaps), with efficient visibility culling of light volumes
Quirky materials framework
Voxel-based terrain, editable in real-time, with Lindstrom-Turk edge-collapse mesh optimization, uzing the CGAL library.
Threaded Python scripting for the physics system - mainly used to make autonomous robotics simulations that can query their environment and send commands to servos/motors/actuators/etc
Automatic environmental greebling details like grass, decals, etc using 3d perlin noise to keep distributions naturalistic

Squizit

Source code on Github

iOS implementation of classic dadaist Exquisite Corpse game.

Skills

Woodworking

Professional Experience

2022+:Video Apps Engineer, Apple
2020-2022:Graphics Engineer, Streem LLC At Streem I have been responsible for optimizing and extending the iOS graphics pipelines for Streem's AR applications. I have developed custom rendering paths, optimized existing ones, and worked to develop custom user experiences through AR to help customers best utilize the platform.
- Prototyping several different strategies to optimize scanning a user’s space both in terms of speed, quality, and enjoyment
- Implementing graphics pipelines for the above (mostly via ARKit, but a fair amount of custom metal pipeline and shader code)
- Optimizing the graphics pipeline for both performance and quality of appearance
- Testing these prototyped experiences with users, and developing a final polished experience which is currently shipping in the Lowe’s app.
- This work won an AWE "auggie" award for Best Consumer App, see also the accompanying promo video
2019-2020:Software Engineer, Bluehawk LLC, contracted to Google In my work for Google (through Bluehawk) I was responsible for building a tool for identifying the nuances and corner cases of Android performance, to aid in making Android a better platform for games. In this role was responsible for designing and building the testing framework, data reporting/analysis, and a suite of tests which exercise OpenGL, multi-threading strategies, and other performance-oriented tests relevant to game engine designers.
2016-2019:Software Engineer, Rapid Prototyping at Vulcan, Inc At Vulcan I was responsible for prototyping Paul Allen’s vision with a goal towards productization and IP generation. My work at Vulcan focused on AR/VR experiences, but dabbled in other directions at times:
- Augmented reality in-stadium fan experience for the Seahawks for AR glasses and phones built in Python/numpy, Unity and native C++
- Hololens-based security glasses experience (ML backend) to aid personnel in recognizing persons of interest on a property, built in C#, C++ and Unity
- Developer simulator for Vulcan’s Holodome, built in C# for Unity
- Input calibration for Vulcan’s Holodome installations, built in C# for Unity
- Multi-camera synthesis for simulating “body presence” in virtual reality with a network layer built in C++, and user experience in C# for Unity
- Android-based data collection/distribution system for health workers in developing nations to monitor trends to detect possible outbreaks
- Indoor location tracking for venues to improve customer experience while preserving user privacy built in Swift on iOS
1999-2016:Art Director & Client-side/Interaction programmer, mobile application developer, APCO Worldwide.Designer and implementer of client side user experience for websites, mobile apps, and so on.
- Fully responsive web application front ends written in HTML, SASS/CSS, and Javascript
- Native mobile applications for iOS and Android, written in Objective-C, Swift, and Java>
- Designed user experiences in Sketch, Photoshop, and Illustrator
- Prototyped user experiences using web technologies (HTML, SASS/CSS, Javascript)
2013-2015:UX Designer, UI Designer, Full-Stack Developer for ConsultPro (startup) I was responsible for the UX design, UI design and implementation of an iPad app for Hair Salons. I was also responsible for designing and implementing the network sync prototcol that enabled all signed-in devices to see and work with up-to-date data.
1997-1999:Graphic designer, UI designer, & UI programmer, University of Virginia, Darden School of Business.Responsible for designing and building educational tools in Macromedia Flash & Director.

Personal Work

In my free time, I write silly experiments in Rust, C++/OpenGL, and so on.
