title: Texturing Opengl Terrain?
body: <p>What is the best way to texture terrain made from quads in OpenGL? I have around 30 different textures I want to have for my terrains (1 texture per terrain type, so 30 terrain types) and would like to have smooth transitions between any two of the terrains. </p>
  
  <p>I have been doing some browsing on the web and found that there are many different methods, including 3d texturing, Alpha channels, blending, and using shaders. However, which of these is the most efficient and can handle the amount of textures I am looking to use? For example: <a href="https://stackoverflow.com/questions/1110844/multiple-texture-images-blended-together-onto-3d-ground">This popular answer</a> describes how to use some techniques, but since the mixmap only has 4 properties (RGBA) and so can only support 4 textures. </p>
  
  <p>I should also note that I know nothing about shaders, so non-shader required techniques would be preferable. </p>
