hello grp....(adsbygoogle = window.adsbygoogle || []).push({});

is there any algorithm of findin the total area of an intersecting plane. i have tried with set theory if a n b r two planes,

area(a)+Area(b)-Area(a intersection b)

but it takes such a long computation when u go on adding planes to the existing ones. I want to have something which cud b easily programmable....without takin much longer 4 computations(by the processor)...

So is there any new method.....

thnx in advance
