Visualizing Leap Motion data, 3D Graphs and objects.

[coqwas]

HI,

I have recently started a project using a Leap Motion hand tracking device. I am able to communicate fine and extract all the frame data, the data I'm most interested in is the (stabilized) XYZ finger (pointable) position.

I am struggling with plotting these points in 3D space, which type of 3D graph to use, or 3D picture frame?

Eventually I want to be able to load a 3D object (standard regular shapes to begin with, ideally STL ASE VRML objects later) into the 3D space and monitor the finger XYZ co-ordinates and feedback when they make contact with the shape.

Thanks in advance.

Hi coqwas,

I've found an example which should be helpful for loading the STL format, I'll look into some other methods as well.

Load an ASCII STL file into LabVIEW 3D picture control

Hi coqwas,

Here is another example which will work with ASE, STL and VRML.

Robotics Simulation Utility using 3D Picture Control

Hope this helps.

Best Regards,

Thanks Chris!

The robotics simulator is a very useful link.

My main problem is still plotting the xyz coordinates on a 3D graph, I have included a screenshot of my attempt, but I'm getting a miss-match of data types (obviously), I have tried every combination of bundles clusters but all to no avail 😕

I have been looking at the "Creating Points and Lines" example vi

any advice?

Thanks again!
