3D picture control importing objects

[mak007]

Hi,
I'm having problem with importing round objects, from Solidworks (*.wrl files) to labview 3d picture control, like sphere or cylindar with extruded cut. Does anyone experienced this problem or knows solution?
thanks.

wrl files are really VRML text files. I do not think the 3D picture control has any functionality to support wrl files. It is basically just an OpenGL based control and any import from a specific format would need to be coded somehow.

Rolf,
As a matter of fact, the LV 8.20 release has dedicated functions to import WRML (and other formats) files, in the Graphic & Sound/3D Picture Control/File Loading subpalette.

I know the are blocks for importing files, but they're not funcional. there is a picture in attachment so you can see result of importing file from Solidworks 2004 to Labview 8.2.

Hmmm, that is pretty interesting. I wonder which free Open Source VRML library they use for that. It seems very unlikely to me that they might have developed their own and buying it seems a little like overkill to me unless they are planning on extending LabVIEW into 3D VRML authoring.

I also tried to import a few wrml files picked up on the internet. No succes yet. Anybody with more luck ?

Well, WRL is not always the same. There are many varients and complexities and some will only work with certain VRML Players. If the function however fails to even import simple static WRL files then there is something bad. Under http://cnx.org/content/m12977/latest/ however is a description of a Solidworks project to import into LabVIEW 8.20 so I would assume this to work. The inverted pendulum visualization which is supposedly a Solidworks animation looks quite nice.

I saw that example earlier, and I don't have any problems with importing rectangles or cubes from solid (wrl must be VRML 97) just round objects.

Hello Charly,

When i try to import an Vrml object from an exported part from IronCad, i only get to see it if i remove the last object ?
I don't know why but i think it has to do with the light sources.

It's difficult to debug for me because, i don't understand the all the relations of objects and licht sources etc.

Is there a tutorial somewhere ?

Hi Wazig,

Here is a tutorial on Creating Advanced User Interfaces with OpenGL Based 3D Visualization with a section showing how to import a VRML file:

http://zone.ni.com/devzone/cda/tut/p/id/3170

Is this the tutorial you were looking for? Please let me know. Thanks!

Best regards,

Steven
