Objective
Develop excellent software. I'm mainly interested in computer graphics but am open to other challenges.
Experience
Maintaining and supporting our proprietary software renderer
for film and TV visual effects. Developing and migrating
shaders for renderers such as RenderMan, Arnold, and IRay.
Worked on a small team developing a proprietary software renderer used
for visual effects in feature films and commercials. Interacted with
artists to address rendering issues.
Maintained and supported
irradiance caching, subsurface scattering, shadow mapping, photon
mapping, and displacement. Highlights:
- Added multi-threaded rendering mode. Efficient parallelization of the pixel loop, shading, subsurface
scattering, deep shadows, photon maps, irradiance cache, shading cache, hair reflection cache, etc.
- Extended irradiance cache with gradients, neighbor clamping, smoothing, and stable
placement.
- Added adaptive sampler, reduced caustic noise, implemented deterministic sampling
techniques.
- Prototyped Open Shading Language support.
- Ported hair shaders to Houdini.
- Migrated department software codebase to new compilers and architectures.
Implemented a global illumination renderer. Adapted it for
precomputed illumination of levelsets of 2D and 3D scalar heightfields for
my thesis.
Developed scientific visualizations
(including
brain,
neuron,
molecular
dynamics,
and steam
cleaning)
for use in a variety of publications.
Developed software tools,
managed a student assistant, and
assisted others with programming and graphics problems.
Two major site redesigns,
plus two additional websites for other departments. Wrote
software
to provide site-wide visual consistency. Coded several
secure, interactive web-based applications (Perl CGIs). Installed apache,
proftpd, webinator. Provided web-related technical assistance,
poster design, photography, configuration, and backup.
