Pixelmap or image from 3D control?

[tbd]

Hi,

      How can I grab the current 2D view from a 3D control, as a Picture, pixmap, or image-type?

Thanks!

Hi,

You can use the 3D picture control "Render to Image" method. This method returns an image of the scene.

where Marcus teaches us how to insert the 3d graph in a PowerPoint presentation. He recieved 18 5-star ratings for that one.

Dear Tunde and Ben,

      GREAT!  while it's Tunde's solution that I needed...

.. it was fun to bump Marcus's post - which currently stands at 20/5.0!

Cheers!

Doh!  Sorry Tunde, I don't see a 3D picture control - only 3D graphs (which don't provide a "Render to image" method.)

I'm using 7.1 "Full" maybe that's why I'm not seeing the 3D picture control(?)

Graphs do have an Image property - but it's a "Picture" reference (the wire is teal colored, not blue!)  This "Picture" reference has a "render" method, but that exposes only scalers - 6 or so.  The 3DGraph's Picture-reference also has a "Handle" attribute, but that's another dead-end without more info.

I would like to automate the extraction of the image (or pixlemap) for a 3D Graph control!

BTW Tunde, you're BLUE!?  How'd you do that?

Cheers!

`Hi TBD,

That can be a little confusing the first time you run into into it.

The reference that LV creates on the BD when you drop a 3-d graph is a reference to the CW 3-d graph that runs inside an ActiveX conatiner.

Got to the FP and right-click on the freame of the 3-d graph and do a "create reference" (or invoke node) and you will get reference to the ActiveX container.

If you get a chance post an example.

Have fun!

Ben

Quite right - I didn't realize the FP control and diagram terminal referred to [slightly] different objects.

Well, I'm not sure what you might be expecting, but here's a GIF built from one of LabVIEW's 3D Examples.

Also attached is the GIF writer - which may be available at OpenG (under Picture lib.)

Cheers!

(and have fun   - )
