Virtual Reality
(2013-2016)
Projects
Researched rendering improvements for image
quality and performance regarding lens
distortions in head-mounted displays like the
Oculus Rift.
•
• Implemented
renderer with eye tracking
calibration procedure and foveated rendering to
save performance in the Oculus Rift DK2.
Advanced
in-home streaming
(2012-2014)
•
Innovating in the area of in-home streaming to
reduce latency by a factor of 2 plus increased
image quality.
•
•
•
Streamed app feels like running locally.
Open-sourced the frame work.
Android NDK app. Server: Windows, Linux, Mac.

Wolfenstein:
Ray Traced
(2010 – 2011)
Enhancing the new Wolfenstein game with ray tracing
• Created vision and founded the project to
demonstrate benefits of Intel’s Xeon Phi
hardware.
• Developed cloud-based rendering setup for realtime performance from servers towards thin
clients.
• Programmed the cloud setup with server and
client code in C++ to run under Windows and
Linux, added basic game code, support for new
model formats, animations etc. in C++;
implemented all shaders in self-created shading
language, orientated at HLSL
• Enhanced original content with high detail
chandelier model, car with reflections, a multiscreen surveillance station etc.
• Modified the game content to deliver best
performance using ray tracing (e.g. modifications
to handle 250 light sources, removing two-sided
geometry etc.)
• Implemented particle system with scripting
language
• Achieved close to linear performance scaling in
the cloud
• Support for notebooks and netbooks as thin
clients to run (streamed) fully ray traced games
• Support for up to eight Xeon Phi cards in a single
machine to combine their calculation power
(comparable to SLI/CrossFireX, but better scaling)
• Showing demos at various venues like Intel
Developer Forum
• Huge press feedback on almost all major tech
sites
• Received various Intel-internal awards

Quake Wars:
Ray Traced
(2008 – 2009)
Enhancing “Enemy Territory: Quake Wars” with ray
tracing.
• Created vision and founded the project to
demonstrate benefits of modern multi-core
architectures, to highlight technology leadership
and find research topics for ray tracing in games
• Support for new model formats, animations, multithreaded skinning etc. in C++; implemented all
shaders in HLSL-like language
• Worked with ray tracing library team on
requirements,
APIs,
bug
fixes,
tutorials,
performance optimizations etc.
• Enhanced and modified original game content to
deliver the best experience in a ray tracer.
Examples are adding a reflecting scope to a
sniper rifle, a physically correct simulated dome
made of glass, various implementations for water
with reflections and refractions.
• Runs on Windows (32 and 64 bit) and Linux
• Worked with the team on porting the demo to
Larrabee
• Showing the work around the world (CeBIT,
SIGGRAPH, Games Convention, Research@Intel
Day) and in an Intel Developer Forum keynote as
the only Intel Larrabee graphics demo ever
• Huge press feedback on almost all major tech
sites.
“The game itself was vastly expanded when
compared to original title” - TGDaily
• Received various Intel-internal awards
