  • Responsible for technical direction, design and architecture of the code base
  • Lead team to create a new DX11 code base with competitive feature set
  • Managed scope and feature approvals for the engineering team
  • Collaborate with art leads to establish new process and pipeline for asset creation
  • Work with production to establish project schedules and milestones
  • Project lead for game finalization and shipping

  • Optimisation of the Unreal render pipeline to reduce GPU time by 2.0ms.
  • Worked with a team to solve and isolate bugs and issues with the Natal hardware, platform and third party software (GFx, WWise).
  • Changed the render thread pipeline to reduce execution time to stay within performance target.
  • Primary person responsible solving for crash bugs and soft locks.
  • Worked with a team to help keep the game within performance targets.

  • Shared in the design of a brand new engine code base to be used for a new AAA title (Xbox360, PS3, PC).
  • Implemented a cross-platform rendering system and render resource manager.
  • Implemented an asynchronous loading system for all level assets.
  • Implemented a basic scene graph for frustum culling, per-object light lists and shadows.
  • Implemented a cross-platform engine job system for cpu load balancing of work units.
  • Implemented base actor class. They served to keep the system entities synchronized (animation, rendering, physics, pathing and game) and to serve as a base for the update cycle (specially movement) with a concentration on concurrent processing.
  • Improved the engine framework to work in a multi threaded environment. Modified the game loop to allow for concurrent processing and fixup of game data.
  • Render system is run completely concurrently and asynchronously to the game thread - shared in the responsibility to create the methods in which the two threads update each other and control asset management.
  • Restructured the way that render data is exported and then loaded by the engine. The format went from a multi-packet (with differentiated load systems) to a single packet, single load system.
  • Integrated Havok into the code base. Implemented a simple interface into the Havok system for game side collision requests. Implemented a robust interface for interacting with the Havok Physics system.
  • Helped guide the development process, and mentor the programming team.
  • Worked with the Art Technical Director to define render features and the art pipeline.
  • Liaison with Art and Design to make sure that we were meeting requirements and that assets would be delivered in time.
  • Wrangled the milestone deliverables.
Senior Programmer
  • Pathing system was based on an A* two dimensional model. Wrote a series of routines for constructing an arbitrary walk surface based on a collection of objects (placeables) that had artist defined walk surfaces. Created a routine to validate face to face pathability that was used by the pathing system.
  • Analyzed and optimized the engine to improve performance for a range of PC hardware.
  • Isolated and fixed some rendering issues that were producing ill behaviour, either in visual appearance or in execution time.
  • Modified text and font routines to work with FreeType v2.0 and in general fix issues that arose with UTF8 support (localization).
  • Troubleshooting and firefighting for the shipping product.

  • Integrated O.D.E. (open source physics solver) into the engine code base.
  • Created primitive vs triangle-mesh routines to calculate the penetration depth and normal of intersection, providing for interactions with arbitrary environments.
  • Created continuous collision detection (swept volume) for interactions involving high-speed and/or small geometries.
  • Corrected/Improved a majority of the existing primitive-primitive penetration functions.
  • Implemented a new collision primitive (flat-capped cylinder) using a true mathematically defined cylinder. The common practice is to model a cylinder as an extruded octagon (or other n-gon).
  • Refined the mathematical parameterization of constraints.
  • Modified the methods used to solve the physical simulation ( the calculation of the forces generated by a given set of dynamics and constraints ).
  • Implemented limitations on the system to prevent mathematical divergence in the solution system.
  • Created a debugging visualization system.
  • Refined collision calls for performance on console systems (specifically the PS2).
  • Rigorously tested the collision system for stability and performance. Specific care was taken with floating point limitations (extreme value cases ).
  • Tweaked capsule collisions to provide the predictable, stable results for soft body simulation.

Consultant/Programmer
