   Fragment Shader, texture writing
  Hey I am reading information from a texture in my fragment shader, i then process this information and want to save it. Can i save it directly in the texture - how will i go about this?I know that as a last resort i can use the render to texture extension and simple render the scene to the texture the only problem is that the texture format is GL_FLOAT32, how will that work if i render it to a texture then?   
  i would say: render to fbo
