GPU Gems 2 Coming Soon

GPU Gems 2: Programming Techniques for High-Performance Graphics and General-Purpose Computation, published by Addison-Wesley, is a compilation of chapters covering the latest programming techniques for today’s graphics processing units (GPUs). Real-time graphics programmers will discover the latest algorithms for creating advanced visual effects, strategies for managing complex scenes, and techniques for advanced image processing. Readers will also learn new methods for using the substantial processing power of the GPU in other computationally intensive applications, such as scientific computing and finance.

GPU Gems 2 is hard bound, approximately 800 pages, and printed in full color throughout, with over 300 diagrams and screenshots. It will be released at the upcoming Game Developers Conference (March 7 - 11, 2005). You can sign up to be notified when the book is available.

Cg 1.3 Released

This 1.3 release of Cg introduces several significant new features:

  • New 'vp40' profile, that enables texture sampling from within vertex programs
  • New 'fp40' profile, that provides a robust branching model in fragment programs, and support for output to multiple draw buffers (‘MRTs’)
  • Support for writing more than one color output (i.e. ‘MRTs’) in the arbfp1 and ps_2* profiles
  • New semantics to access OpenGL fixed-function state vectors from within ARB_vertex_program and ARB_fragment_program
  • New ‘-fastprecision’ option for arbfp*, fp30, and fp40 profiles, to use reduced precision storage (fp16) when appropriate.
  • (New in Cg 1.2.1) The 'arbfp1' profile will attempt to generate code differently if the 'MaxTexIndirections' option is set to some non-zero value.

NVShaderPerf for Forceware 71.80 Drivers Released

This latest version of the NVShaderPerf command line utility uses the same technology as the Shader Perf panel in FX Composer to report shader performance metrics for Forceware 71.80 drivers. It supports DirectX and OpenGL shaders written in HLSL, GLSL, Cg, !!FP1.0, !!ARBfp1.0, VS1.x, VS2.x, VS3.x, PS1.x, PS2.x, and PS3.x. You can get performance reports for your shaders on the entire family of NVIDIA GPUs, including cycle count, register usage and pixel throughput metrics.

Tip of the Month
 

Don't use the Read Time Stamp Counter (RDTSC) to do timing in your app. Here's why: It is unusable on mobile platforms because calculations assume a fixed clock speed. Mobile platforms (such as notebooks) will throttle back the CPU at unexpected times making the tick count from RDTSC useless. Instead use QueryPerformanceCounter, which insures consistent architecture independent results.
