О докладчике: Rev Lebaredian began his career at JPL as a Networking Engineer and then transitioned
to high-end computer graphics at Warner Brothers Digital as a Technical Director, and author of the cartoon
renderer for «Marvin The Martian in 3-D». On behalf of Warner Brothers Digital, Mr. Lebaredian presented a
technical sketch at the 1996 Siggraph Computer Graphics Convention entitled, «Traditional Cell Animation
Look with 3D Renderers». Mr. Lebaredian left Warner Digital in the spring of 1996 for Dream Quest Images
to write the hair renderer (Yeti) for «Mighty Joe Young». After completing 'Yeti', he started his own software
company, Steamboat Software, Inc., developing the high-end 3D rendering package Jig. The first version of
Jig received a Computer Graphics World 2000 Innovation Award within five months of its release. Mr.
Lebaredian has worked the past year at NVIDIA Corporation, architecting and developing the technology
which ties Cg (NVIDIA's shading language)seamlessly and unobtrusively into the application.
Programming Real-time Graphics with Cg
Докладчик: John Spitzer, NVIDIA Corporation, Director of Developer Technology
Аннотация: GPUs are becoming more and more complex with every generation, with the latest generation
introducing general programability at the pixel level. Cg (also known as HLSL) allows graphics programmers
to access the newest features through a cross-platform high level language, without being burdened with
assembly language shaders. This presentation covers the details of the Cg language, as well as how you can
hook it into your application and development workflow.
О докладчике: John Spitzer is Director of Developer Technology at NVIDIA Corporation where he
oversees development of tools, technology, art and educational materials for the 3D software development
community world-wide. John collaborates with game developers on a daily basis, evaluating the technology
in their games and assisting in the implementation of advanced visual effects. John has participated in a
number of industry standards committees relating to 3D graphics including the OpenGL Architectural
Review Board (ARB) and serving as a founding member and Chair of the SPEC OpenGL Performance
Characterization (SPECopc) organization. While serving on SPECopc, John defined, designed and
implemented the industry standard SPECglperf benchmark. John presents at many developer educational
events each year on topics ranging from performance optimization to advanced shading techniques. John
holds bachelors and masters degrees in computer science from Rice University.
Graphics Performance Optimization
Докладчик: John Spitzer, NVIDIA Corporation, Director of Developer Technology
Аннотация: Good performance is about finding and eliminating bottlenecks as they appear in your game.
This presentation covers each of the areas in the graphics pipeline that may potentially become bottlenecks:
CPU, geometry transfer, vertex processing, primitive assembly, rasterisation, shading and framebuffer
operations. For each area, we will discuss simple diagnostics for determining whether or not it may be a
bottleneck, and actions you can take to improve performance or eliminate the bottleneck altogether. This
presentation covers both industry standard APIs for 3D graphics: Direct3D and OpenGL.
