How to built a surface using 3D points   
Hello,

I think this is the right place for asking my question. My project need to collect lots of points in a coordinate system
 and construct them into a surface with spline interpolation(e.g.NURBS..).

Since I have no experience with computer grapic, I do not no where to start. Maybe I should begin with drawing points?

My former application has been built in Phab, and the surface will be part of the whole project. Is it possiable?  how 
can I creat a windows to diaplay the surface in PhAB?

Any help is appreciate!

Jason

Hi Jason!

So just to clarify ....

Do you want a Photon program that makes GF calls

OR

Do you just want a GF program?

You can do both, and there are examples available for both 2D and 3D.  Just let me know what we want, and I'll let you 
know what to download.

Kind Regards,
-Derek

RE: How to built a surface using 3D points   
Hello Derek,

Thank you very much for your response.
I think I need Photon program make GF calls, because it will be a module of a Phab application. I plan to get some 3d 
points first, and then use this GF function to interpolate or approximate these points into a surface.

This is what I am thinking about the function now. What will be useful for me and any suggestion please?

Many thanks and best regards,

Jason

Hi Jason,

Please check these out, one if Photon and 2D GF, the other is Photon and 3D GF, and another is a mix of all three.
