I am trying to use the GPU for scientific computing and was looking at an fpbuffer as a good rendering target to use before reading the results back to the GPU. I am finding it difficult to get any good information on what the fpbuffer offers in terms of functionality. The vectors that I want to work on are going to need more than 8 bit precision per component, can I use a C float (x86 win) level of precision per component? i.e. do fpbuffers offer higher levels of precision than a regular pbuffer?
thanks for any help on this.
