   Rendering to Floating Point Textures
  Hi again,I've been doing some research and I wanted to ask you guys.  What is best method of rendering to a high perscision texture in OpenGL.  I have an nVidia 6800 so I want to render to an float 32 render target.  I actually only need to store 2 32bit float numbers so using Luminance and Alpha or Red and Green would be good.I'm looking at pbuffers and FBOs.  It seems FBOs are the fastest am I correct.  Also is there any good documents or links out there for doing this kind of thing?  I've found very little in terms of how to render to texture.   
  Use FBO's... A good place to start is with the extension site.http://oss.sgi.com/projects/ogl-sample/registry/EXT/framebuffer_object.txt;  Here's a very good site about render-to-texture, FBOs, floating point textures etc:http://www.mathematik.uni-dortmund.de/~goeddeke/gpgpu/tutorial.html
