There is a paper here: http://fulltext.study/download/439400.pdf

I thought that tsplines was patented?

Hello Brian,

If I understood it right, it isn't an implementation for manipulating and processing in a CAD-application. It's more a proposal of a special datastructure for import/export T-Splines between different applications with a Step-extension. So I don't know if it touches the Sederberg patent. I've compiled the code, but the STEP output needs an application which supports the special EXPRESS-extensions. Very interesting for people with a lot of mathematical knowledge or a lot of time -so nothing for me.

Have a nice day
Karsten
p.s.: Thanks for the link - I didn't find it:-)

Thank you Karsten.

Hello Brian,

I agree with you - for the next 7 years we will find some other interesting stuff;-) or the forum will bring them to us:-)

Have a nice day

Maybe something like that?

Sure I have not said that will easy or even possible! :)
For the moment we have yet our eyes! ;)
Thx for the time's reflexion!
