Hi boosters, Further to Noah Steins message: http://lists.boost.org/Archives/boost/2005/10/95348.php I have attempted to make an implementation of grassmann points as intermediate results of cartesian point addition operations. Its available as "grassmann_point.zip" in the (new) "Graphical" directory. There is a file test.cpp in the "boost/lib/graphical/examples" directory Any comments welcome. ( Mathematicians help would be appreciated to verify whether the concepts are correct too. My grasp of grassmann spaces etc is shakey to say the least) . Enclosed is the header grassmann_point.hpp to give a flavour of the type. (Of course to run it you will need the other files in "grassmann_point.zip"). Only tested in VC7.1 All comments welcome... regards Andy Little begin 666 grassmann_point.hpp M(VEF;F1E9B!"3T]35%]'4D%02$E#04Q?5%=/7T1'4D%34TU!3E]03TE.5%]( M4%!?24Y#3%5$140-"B-D969I;F4@0D]/4U1?1U)!4$A)0T%,7U173U]$1U)!

Hi boosters,
Further to Noah Steins message:
http://lists.boost.org/Archives/boost/2005/10/95348.php
I have attempted to make an implementation of grassmann points
Unfortunately my implementation seems to be grossly simplistic and innaccurate. I underestimated the complexities of grassmann points. I am about to update the zip file in the vault ("Graphical" directory) so that the grassmann_point operators have no calculations. (Hopefully I can fill these in at some stage!). Meanwhile Sorry for the noise!. Any help on implementing the calculations would of course be appreciated.OTOH if the calculations are too costly, that would seem to rule this method of point addition for performance reasons. Apologies again Andy Little
