title: Texturing Spheres with Cubemaps (not reflection maps)
body: <p>I want to texture a sphere with a cube map. So far my research has thrown up many many results on Google involving making OpenGL auto generate texture coordinates, but I want to generate my own coordinates.</p>
  
  <p>Given an array of coordinates comprising the vertexes of an imperfect sphere (height mapped but essentially a sphere) centered on 0,0,0, how would one generate texture coordinates for a cube map?</p>
