OO O OO 2004 Open Season - Sony Pictures Imageworks
O O OO O
O O OOO created tool for rendering maya scenes with Renderman - compiling
O O O O O Maya's shader networks into Renderman shaders (functionality very
O O O O similar to Pixar's "Renderman for Maya".) led team of developers to
OO O O extend functionality.
OO O OO
O O O O created tool for translating Maya scenes to in-house tool "birps",
O O O O greatly reducing time required for lookdev. (prop lookdev time
O O O decreased by 80%.)
O OO O
O O O O created tool for modeling/rendering trees.

O O OO O 2003 The Matrix:Revolutions - ESC Entertainment
O OOO O O
O O O O called in to assist sentinel swarm team meet production
O O O O deadline. created software to "destroy" sentinels - using both
O OO OO O a hand-animated library for gross movement and dynamics for
O OO OO O sentinel legs and debris. handled difficult task of transition from
O O OOO "live" mode to "dead" mode. software was used through-out battle
O O O O sequences.
O O OO O
O OO OO O created software to filter undesirable high-frequency jitter from
OO O O swarm animation. created software to re-time swarm animation.
OO OO OO
OO OOO OO worked with the pipeline team to optimize rendering of swarm
O OOO O (created module for their in-house tool "plexus".)
O O OOOO
O O OO OO worked with pipeline team to create utility mental ray shaders.

O O O O 2003 The Matrix:Reloaded - Sony Pictures Imageworks
O O O O
O O OO created tool (Maya) which allowed modelers to easily create miles
O O OO of pipe needed for underground tunnels. created tool to import
O OO O hand-modeled pipe, so that the pipe could later be rendered
O O O procedurally in Renderman.
O O O O O
OO O O O created the "Hindenburg effect" for the Nebukadnezar destruction at
OO O O O the end of "Reloaded". metal burned away from the underlying frame
OO O O O in a way reminiscent of the Hindenberg blimp.
O OO OO
O OO OO created the dynamics system (in Maya) for twisted metal and
O O O O windshield debris for the Nebukadnezar destruction. created
O OOO O particle-based fire and smoke for the explosion.

O O O O O 2002 The Matrix:Reloaded, The Matrix:Revolutions - Centropolis FX
O O O O
O O O O called in to troubleshoot Centropolis' atmospheric renderings using
O O O OO global illumination in mental ray. created a photon-density cache
O O O O mechanism, decreasing render times by a factor of 5.
O O O O O
O OO O created an artificial intelligence system to guide the 600 sentinel
O O OO O attack on the Mjolner in "Revolutions". the system - an advanced
O O O O flocking system - directed the sentinels in a high-speed chase in
O O O O O which they attacked in coordinated groups, dodged incoming fire,
OO O O O landed on the Mjolner, crawled along its surface in pursuit of the
OOO O O broadcast antenna. learned Maya in the process of development -
OOO O O O completed task in 10 days.

O OO O 2001-1999 mental images
O O O O
O O O OOO worked to create a "phenomena" (shader) library for the mental
O O O OO ray renderer, and then release the collection under the title
O OO O O "Phenomena for mental ray" to be published by Springer Verlag. the
O OO OO project has been cancelled.

OOO O O O 2001-1999 Washington University - Adjunct Faculty
OOO O O O
O O O O created and taught courses in computer graphics (both undergraduate
O O OO O and graduate level) including "Computational Art" and "Graphics
O O O O Laboratory".
O O OO O
O O OO O coordinated a student effort to create a data-flow based graphics
O O O O O library similar in function to Houdini.
O O O O
O O OO O coordinated a student effort to create (with a budget of $500) a
O OO OO O real-time virtual water environment. "The Waterworks" has shown at
O O O O O several prestigious events, including SIGGRAPH 2001.
OO OO OO
O OO O at the time of this writing (2005) Washington University is ranked
OO O O O at 11th place in US News and World Report's list of top national
OOO O O O universities.

O O OO O
O OO O O
O OO OO 1999-1996 Lume - Founder
O O O O O
O O OO O created a suite of photo-realistic tools for the mental ray
O O O O renderer. the tools used the then-ground-breaking technique of
O O O O high-dynamic-range light, creating impressive water, metal,
O OO O lighting and atmospheric renderings.
OO OO O
OOO O O O founded the company Lume, Inc., and supervised the porting of the
O O O O OO tools to Renderman, Lightwave, Maya, and 3D Max.
O O O OO
OO O OO O
O O O O O
O OO O O 1997-1995 Cyan - Riven: The Sequel to Myst
O O O O
O O O O O created the shader collection used in the rendering of Riven,
O O O O including shaders for lighting, atmosphere, water (surface,
O O OO subsurface, and displacement), metals, terrain, etc.
O O O O
O OO OO O created the render queuing software used by Cyan to efficiently
O O O exploit their render farm.

OO O O OO i have 20 years experience developing software under a variety of
O OO O O operating systems and languages and design paradigms - primarily
O OO O unix based - including Solaris, Irix, Linux, BSD, MacOS 9 and 10,
O O O Windows, etc. C, C++, Objective C, assembly, Scheme, perl, tcl/tk,
O O O O awk, sh/csh, Postscript, etc. i have done development with the
O O O OO following software packages: Maya, Houdini, Softimage, Renderman,
OO O O O mental ray, Lightwave, Entropy, Shake, Eddie, Photoshop, The Gimp.
O OO O O
O O OO i placed in the 98th and 99th %ile for the computer science and
OO OO O O math GREs, respectively.
O OO O O
O OO O O i was first published nationally at age 15 (Analog Magazine,
OO O OO O February 1986.)
