Are you aware of any Catmull-Rom Spline implementations...

[dmafackler]

Specifically in LabVIEW.

We have an application for image correction that will make use of this class of splines.

Otherwise rolling our own based on DirectX, OpenGL, or implementing based on prior work:

The Catmull-Rom spline algorithm guarantees that the generated spline path passes through the provided points.

This brings back memories of a project I worked on 10-15 years ago. We bought a vision system solution that was to characterize the performance of an analog pressure gauge and calculate a custom non-linear dial. It appeared that their curve-fit forced the path to go through each measured point and the dials looked horrible - graduation marks bunched together in some points, spread way out in others. There was some inaccuracy in the measurements so the gauges weren't accurate. I changed to a polynomial fit and Bob was my uncle.
