Ubuntu 9 3D desktop

The 3D Desktop of Ubuntu Karmic Koala edition. It's nice to see new concept to handle multiple workspace (virtual desktop) on a single screen. It use compiz (transparency, sphere, cube, cylinder...).

Augmented reality in train station

I have see in the Paris (Gare de Lyon) train station a augmented reality application.

Basically it show the shops, train places, train station reception desk. The screen is touch sensitive and you have to turn the screen in the indicated direction and a video show you the path you have to follow to go to the desired place.

It works not so bad. The system is called "DirectiVision". I cannot know more about the company for the moment because the website is under construction. (a french company).

The system do not use computer vision system (I think), only a rotation sensor to know in which direction the user look at.

DX11 Tech preview "Heaven Benchmark"

The Unigine team have released a new tech demo called "Heaven Benchmark" to show the advantage of using DX11 for Hardware tessellation purpose.

The following features are demonstrated:

  • Support of DirectX 9, DirectX 10, DirectX 11 and OpenGL
  • Comprehensive use of tessellation technology
  • Advanced SSAO (screen-space ambient occlusion)
  • Volumetric cumulonimbus clouds generated by a physically accurate algorithm
  • Dynamic sky with light scattering
  • Interactive experience with fly/walk-through modes
  • Benchmark mode

     The video of the demo:

    To see in real time the Hardware tessellation you can see this video (Tessellation On/Off) :

    Hardware tessellation look promising and give an excellent way of have a nice vertex map to fit the best to be adapted to the height map and so give the best visual result (compared to Parallax mapping).
