NVIDIA Demos
From Wikipedia, the free encyclopedia
In order to showcase the prowess of GeForce chipsets, NVIDIA creates technology demos that render in real-time on the chipsets in question (while videos are usually also made available). This listing attempts to mention recent, more notable releases.

[edit] GeForce FX
[edit] Dawn
Dawn is likely the most well-known NVIDIA demo-piece yet. It was crafted to display the power of the GeForce FX series. Dawn is a forest fairy, and is used as the basis for some later NVIDIA demos. The demo features extensive use of the card's shaders.
[edit] Dusk
This demo was timed to appear during GeForce FX 5900's release. The eponymous main character Dusk is highly reminiscent of Dawn; sharing her wings, hair, and a similarity of form. She could be an urban version of Dawn, a striking opposite of the faerie's soft leafiness in her black street outfit. The Dusk demo added realtime shadows that were not present in "Dawn".
[edit] Vulcan
Vulcan is another FX 5900 demo. It features volumetric shading and multiple light sources.
[edit] GeForce 6
[edit] Timbury
Timbury, an entomologist that draws pictures of his specimens, stars in this demo created for the GeForce 6 series.
[edit] Nalu
Another GeForce 6800 demo, Nalu features a mermaid, based again on Dawn.
[edit] Clear Sailing
Once again using a marine theme, this demo showcases the animation of liquid on the GeForce 6 series. A pirate ship seeking to escape its regal pursuer on the high seas demonstrates water surface, foam and splash effects, along with enhanced fire, explosions and smoke.
[edit] GeForce 7
[edit] Mad Mod Mike
The rotund, jetpack-clad mountain of a man in this GeForce 7800 demo mods the formerly-wimpy computers of gaming enthusiasts everywhere into blazing performance rigs. Demonstrates PixelShaders 3.0, Radiant Lighting and Depth of field.
[edit] Luna
Something of a throwback to the abstract science fiction themes of the demoscene, this GeForce 7800 showcase once again features an eponymous female form, levitating with an intricately rendered head of hair. Again, upgraded shaders are used.
[edit] GeForce 8
[edit] Adrianne
The Adrianne demo uses complex shading and deformation techniques typically reserved for offline-rendered animation. Adrianne's skin shader is the most complex in the scene; 1,400 instructions per pixel, 15 render passes, five separate bump maps, and a complex, physically-based lighting model that simulates sub-surface scattering.
[edit] Froggy
The skin shader is a modified version of the Adrianne skin shader with modified scattering properties derived from photos of real frog skin. The shader has high-detail bump and detail maps and a complex, physically-based lighting model that simulates sub-surface scattering.
[edit] Box of Smoke
As you move the smoke generator within the box, the computational fluid dynamics simulation is being processed in real time on the GPU.
(The Box of Smoke demo allegedly also runs on nVidia's Geforce 6 and 7 series, whereas Adrianne and Froggy require an 8 series to run.)
