[Toon-members] Re: [libcvd-members] template error in tag-20090724

[Gerhard Reitmayr]

Hi,

I suggest not to use four point pose algorithm anymore. That's why I  
excluded it from the build and marked it deprecated in the  
documentation. These are reasons not to use it:

- there is a three-point-pose algorithm in tag that is
  - faster
  - numerically seems to perform better
  - does not require SVD (dependencies on LAPACK)

cheers,
  Gerhard
