Calculating area of surface #2

Closed yconst closed 10 years ago

yconst commented 10 years ago

First a big thanks is in order for a great library.

My question is, is there any command to calculate the area of a surface? If not, is there any other way of doing it?

Thanks.

Hi,

I know that at some stage area calculations functions existed, but I think that they were not induced in the distribution due as they were not stable enough. One approach is to do subdivision, and calculate the area of the resulting triangulation. I think this was the approach followed, but it was slow.

Thanks for the reply. I'll try this approach, since in my implementation I am deriving triangles already for drawing.

If I may take the chance to ask, what are future plans for extending SISL functionality?

Thanks

Hi,

The extensions are done in GoTools, there you have CAD boundary structures, 3-variate volumes for Isogeometric Analysis and The novel Locally Refined B-splines.

Many of the algorithms of SISL are integrated in GoTools.

Thanks I'll take a look at GoTools then.
