NVIDIA is offering five special sessions at this year's Game Developer's Conference designed to introduce you to the latest advances and technologies offered.  This year's sessions are no exception.  We will be offering the following talks this year:

  • NVIDIA APEX: From Mirror’s Edge to pervasive cinematic destruction
  • The In and Out: Making games play right with 3D Stereoscopic Technologies
  • CUDA and Multi-Core Gaming: Lessons from Gamebryo Floodgate
  • NVIDIA APEX: High-Definition Physics with Clothing and Vegetation
  • Platform-independent shader development with mental mill: the making of Dead Rising 2

You can find additional details on the NVIDIA GDC 2009 page.  We encourage you to visit that page from time to time, as we will be announcing more details as GDC draws near.

We've updated the beta of version 5 of NVSG, the NVIDIA Scene Graph API.  This beta supports 32 and 64 bit versions of both Windows and Linux.  Some of the features of this release include:

  • Native support for loading MetaSL shaders
  • Cg 2.1 support for expanded rendering capabilities and better performance
  • Render framework optimization, delivering substantial performance improvements – especially for larger, shader-bound scenes
  • Massive scene capabilities from NVScale functionality on Quadro Plex systems
  • 10-bit/component color support for significant image quality improvements when used with compatible hardware.
  • New stencil buffer support, including a new StencilAttribute, enabling stencil buffer operations to occur per drawable.

PhysX Visual Debugger (PVD)

The PhysX Visual Debugger (PVD) allows you to visualize, debug, and interact with your PhysX application's physical scene representation. 

The PVD offers the following powerful features:

  • View object frames, contact points, bounds, velocities, center of mass, force fields, and more
  • Left-click and drag to interact with objects
  • Examine the complete set of physical properties for each physical object
  • Object transparency for complex scenes
  • Up-axis definition for compatibility with various scene formats
  • Orbit and flythrough cameras
  • Left-handed and right-handed coordinate systems
