3D Artwork: multiple meshes in one view

[kulod]

Hi,

I am a newbie to iText and I want to render multiples meshes (stream in U3D format) in one view.

I tried to add multiple PdfAnnotations to one PdfWriter but this doesn't work. Is it possible to add several streams to one PdfAnnotation or what should I do?

Thanks in advance.

You will need to learn the U3D format and merge them in that format, then put the single stream into the PDF.

But whats about the nodes described in 13.6.4.7 of the PDF standard 32000-1:2008? Are multiple nodes included in one U3D file? Are there any libs to create U3D file?

By the way there is a problem with PDF standard page 537, so it can be displayed on my computer.
 

[Leonard Rosenthol-3]

Second sentence of 13.6.4.7 - "The 3D artwork shall be contained in the parent 3D stream object."   The actual artwork (vertices, nurbs, etc.) is in a single U3D stream.   I don't know about U3D libraries - do a web search.

What is the problem with the PDF?  Can you please be specific?

Also, are you using the version from the Adobe site or from ISO?

Leonard

I am using the reference from http://www.adobe.com/devnet/pdf/pdf_reference.html .
If I go to page 537 a message appears:

[Leonard Rosenthol-3]

can't read that :(.   Can you shoot just the dialog?

Also, that looks like an old version of Adobe Reader.  What version?

You are right I used version 9.x. But now I installed 10.1.2 and it doesn't work, too.

[Leonard Rosenthol-3]

My German is rusty, but it definitely sounds like the file might be corrupted.  Can you re-download and try again?

Leonard

Although I re-download it already earlier, it works only just.

But back to the nodes:
If there is a parent 3D stream object I expect that there can be also sub stream objects?

[Leonard Rosenthol-3]

That would be an incorrect assumption.  Where in the specification do you
see a place to put them?

[kulod]

In the PDF below you can see several models in the model hierarchy. Is this all coded in one U3D file?

Can anybody help me?
