title: Read float values from RGBAFloat texture in Unity 3D
body: <p>It seems people aren't discussing much around floating point textures. I used them to do some computations and then forward the result to another surface shader (to obtain some specific deformations) and that's cool, it always works for me if I digest the results in a shader but this time I need to get those values CPU side so I get a float[] array with the results (just after calling Graphics.Blit that fills the floating point texture). How can this be achieved?</p>
  
  <p>On a side note: the only guy that I saw using this method so far is Keijiro, for example in his Kvant Wall; if you have other sources I'd be grateful if you let me know.</p>
  
  <p>Incidentally, I know there are compute shaders and OpenCL and CUDA. This is the method I need now.</p>
