NVIDIA Texture Tools & SDK 8.0

NVIDIA-SDK 8.0
This release of the NVIDIA SDK includes Shader Model 3.0 as well as hundreds of all-new code samples, effects, and tools to help you take advantage of the latest in graphics technology.

The samples include High Dynamic Range Rendering, Deferred Shadring, Instancing, Multiple Render Targets, Vertex Texturing, Soft Shadows, Perspective Shadow Maps, and much more...

The effects include Flame, Glow, Gooch Shading, Metals, Multitexture-Based BRDFs, Color Controls, a Selection of Image Filters, and much more...

This release of the NVIDIA SDK includes several exciting Shader Model 3.0 samples. In case you missed them running live at GDC 2004, we created several educational video clips we think you'll find interesting. These clips are meant to explain some of the techniques that will be possible with our next-generation hardware. Full source code for these samples and more will be available in the next release of our SDK.

Please note that the video clips were captured from live demos via a digital-to-analog scan converter and then recompressed. Although the voice-over explains the concepts behind each technique, colors and frame rates are not represented accurately and the effective resolution is reduced significantly. Any choppiness in the videos is caused by the capturing and encoding process that was used.
