How can from 2D image I make a 3D in labview

Hi !
I have to do a project on how from 2D image to 3d on LabView!
Thank you for your time in advance.

I did things like that and it was fun.

This thread where we talked about the LV software I wrote for a N-Scale model train layout...

 may be helpful.

I had this image that was taken while part of the layout was hanging from the rafters in my garage and I was doing the wiring.

I used the pixel colors to define the point colors and added a manual control that I could use to define the elevation.

The edges were a bit wavy but since then LV has added a Cubic Hermite spline that would have worked better and helped with the edges.

Now if you want the color to define the Z-values of your triplets, you will have to come up with a method to convert the color to a magnitude. I favor splitting the color into three vectors, one for each of the RGB planes and then find the magnitude of the vector. Map that to the Z-Value for each point.

I hope you have as much fun as I did when I was doing that project!

Hi niks_radev,

did Ben's great project satisfy your needs? What exactly are you trying to do?

Hi, Martiko 

Thats exactly what i need. The problem is that i can not understand why the Highmap image is mirrored. If you could explain that to me that would be great!
