After downloading and reviewing the NI Labs 3D Visualization Demos, we have some questions and issues. We found two examples in the demo package: a VI called Software.vi that uses an Express VI and a 3D Picture Control, and a VI called example_1.vi that uses a new object called a 3D surface plot. Because these are different approaches, it is not clear which direction NI will be taking in upcoming LabVIEW releases. Is the intent to continue to develop the 3D surface plot or merge its functionality into the 3D picture control?
We would like to develop an application that maps data onto a 3D object, an object that we have exported from a CAD package. Software.vi, the example that uses the Express VI, seems to be close to having the functionality we need.

I read some insightful posts above. But can anyone explain to me how the Software.vi VI implements point-and-click selection?
The pick function from openGL casts a ray and returns the first Object it crosses. That is, the meshed object. Where to go, from there, in order to find the actual point coordinates? A meshed object has many points, so I don't think it would be feasible to plot the points as separate individual objects.
Thank you all.
