Yes master i understand the trick of two polygon with epsilon distance

But it cause double work for hardware to deal with them !

I am not familiar with directx or opengl programming a lot !

But i remember there are options for back face culling ... Or similar tasks that will done by Gpu itself !

Are you sure today Gpus nvidia or intel .. Doesn't support automatic coloring of both faces !!!

If there were many fans like you for providing mathematical proofs through Maple ! then in the near future our computer algebra system not only could solve problems symbolicaly even can be a great assistant for helping to underestand proofs more easier

anyone know ? whether both face rendering of polygons are built in the modern GPU ?

Problem  Solved  by Chinese Mathematicians ?
but i could not find any comprehensive materials on web how they expained the solution ?
how they did use power of computer for finding proofs ?
 

thanks a lot Kitonum

it must be very useful for research on pixel based shapes

dear Alsu did you stop posting topics ?

I am proud to Hail Erik Postma

Kitonum thanks a lot

   I admire all  the Maple developers and their team work spirit !

To be a mathematician demand the creed of Pythagoras ... Einstein that made millennium. names for humanity !

Unlike the Stefan wolfram that prefered marketing rather than the Creed of a real Mathematician !

he assuming himself as a prophet like Moses and wrote huge book as Tora and all the rest of mankid must obey the only ten commandments he manage ...

JOHN MAY !

ARE YOU A SORCERER ?

@one man 
if i don't speak so foolish !
i guess your model can be extended so that it simulate a wheel that find its path in a weary road ?
somthing related to tires movment physics !

welcome and nice subject

thanks a lot !
it is so interesting for me !!!

Thanks a lot for your valuable solutions !

The collection of works you published here are prototypes for advanced facilities !
