Reading and manipulation of a VRML model through LabVIEW

[Bijan Najafi]

Hello,

In my application, I would like to read a VRML model through labVIEW and then manipulate it such as doing rotation and translation of the model. I installed the package of 3D picture control. However through this package I am unable to read a VRML model. I also installed Diadem insight for reading vrml model but I don't know how I can connect it to Labview to do image processing through LabVIEW instead of Diadem Insight. Finally I installed OpenGL V.1, but I didn't have any success to read Vrml model. I tried also to use ActiveX for using the function of the viewer of VRML model such as Cortona. But in these ActiveX librares I didn't find any function to load a VRML model. I was wondering if somebody can guide me.

There is a set of VI's that allow LabVIEW to feed data to NI Insight so you can use Insight to handle the rotation and translation of the model. Depending on exactly what you want to do that will probably be the easiest way to do it.

If you want to investigate this option please email me at robert.vandevanter@ni.com.

Dear Robert:
I'm a engineering student, and i'm doing my final project based in LabView.
Reading this thread i've found what i was loking for. I would like to move a vrml through LabView but representing it in INSIGHT. My problem is that i don't know how to generate the .cis archive that i need to make it work like in the examples of the six-axis-robot and the plane. I've got the VRML model only. Could you explain me how can i do it, or recommend me any kind of tutorial for beginners. Thank you very much!
Regards.

Juan,

The CIS files are DIAdem Insight scenes used by Insight. These files are created through DIAdem Insight itself and used within Insight. Some links that may help you are:

These will hopefully give you an overview of how to use DIAdem Insight to create these CIS files
