title: Which mouse picking strategy for milions of primitives?
body: <p>I am rendering models based on milions (up to ten) of triangles using VBOs and I need to detect which of these triangles the user may click on.</p>
  
  <p>I try to read and understand how the "name stack" and the "unique-color" work.
  I found that the name stack can contain at max only 128 names, while the unique-color can have up to 2^(8+8+8) = 16777216 possible different colors, but sometimes there could be some approximations, so it can get modified..</p>
  
  <p>Which is the best strategy for my case?</p>
