RE: [Plib-users] Picking and selection routines

[Allen Y. <ay...@wr...>]

Hi, Steve:
Thank you for your quick response. Does your library support picking vertex?
The project I am working is that we are creating 3D terrain mesh. We want to
let the user to pick any point on the mesh to get exact location data
(latitude and longitude). 

Thanks

I created some 'support' functions inside PLIB's SSG library for this
but they were created especially to support the PrettyPoly modeller and
they are neither documented nor particularly intuitive.

You can dig through the PrettyPoly sources and see how we did it - they
are at http://prettypoly.sf.net

Regrettably, I do not have the time to hand-hold you through the exercise
right now.
