interpolation of points


Trin

Recommended Posts

Hi Lavas,

I have a 3D model of an unknown object which has some hill and Vally. I choose some points on the surface of an object and i want to make a path through it, so i want LabView to find some points between the marked points. I was thinking about interpolation, but if i run an interpolation will the result be some points on the surface again, or may it gives me some points inside the object? Any idea?

The result will depend on what algorithm you chose for interpolation, e.g. linear interpolation, polynormial interpolation ...

Wether the interpolated poionts will located on or inside the original surface, it's up to wheter the mathematic model of your surface happen to be close to the model you used for interpolation. And I think your question is a pure mathematic problem, not related to LabVIEW at all.

(Just Personal idea!)

why dont you build an array from your points... and then you just split the Array into 1D arrays and use the "interpolate 1 D array" tool

once i did something like that in a 3D Surface Graph...

if i can find the example i will send it to you...
