Back in the early days of computer gaming one may remember the Comanche flight simulator. The simple 3D engine used for this and other games is based on a so called voxel rendering engine. Searching the Internet for this technique I found this nice article from Alex Champandard and this one from Codermind. Putting two and two together, again I paid attention to the WriteableBitmap class that is part of Silverlight 3.
To emphasize the .NET Open Space 2009 that is starting tomorrow here in Leipzig, I used a special background texture for the sky. Just press the start button and use W-A-S-D of your keyboard to fly around the terrain. I will clean up the sources after the upcoming and put it here on my blog. So stay tuned.
