title: Any good resource for a XNA voxel based terrain engine?
body: <p>I've been working on my attempt of a game (XNA/C#) for a week now and now I'm that far to create a terrain. I'd most likely use a voxel based engine for this (similar to Minecraft), actually I've tried a lot to play around with Cube tutorials, but most of them are just very basic and don't help me a lot. Right now I've though about following structure:</p>
  
  <p>Game -> Handles main tasks. </p>
  
  <p><strong>--></strong> Invokes World class. <strong>--></strong></p>
  
  <p>World -> Is responsible for all the tasks that happen in the world, keeps the block data.</p>
  
  <p><strong>--></strong> Triggers Block's draw() function after giving over the screen offset <strong>--></strong></p>
  
  <p>Block -> Draws the block at the correct screen position, given by World</p>
  
  <p>However, as I need to render thousands of blocks this could be going quite hard, because I've no experience in 3D programming. </p>
  
  <p>Is it still efficient to do this using the 36 (6 sides x 6 points for 2 triangles) indices method because I could imagine that this eats a lot of memory?</p>
