[openvrml-develop] openvrml

[Corina G. <cor...@ya...>]

Hello, 

Can OpenVRML library be used for loading a vrml file format and 
parsing it? I am interested in transforming a .wrl in a .pcd file and I 
am wondering if I am on the right track. Thanks.

Yes.

Have a look at the prettyprint example for how you can provide your own
semantic actions to the parser.

Unfortunately, I still haven't upgraded OpenVRML to use the latest
version of Spirit. :-/  But what you are asking about can definitely be
done with what's there now.

Thank you for the reply! By running prettyprint I get the following error :

error while loading shared libraries: libopenvrml.so.9: cannot open shared
object file: No such file or directory

Do you know where this comes from?

Thanks,
Corina

It comes from the run-time linker. You need to set LD_LIBRARY_PATH to
wherever you've put libopenvrml.so.

But I'm not sure why the libtool launcher script wouldn't be taking care
of this if you're running pretty-print from the build directories; how
exactly are you building/running things?

Hi,

How did you install openvrml? Or, are any distributions used?
I think that does not install libopnevrml library (libopenvrml.so.9).

How do it become it if "Ldd your application" is executed?

We need more info.

Best regards,
  Nobuhiro

Thanks for the reply, I figured it out. I compiled openvrml from the source
code. I should have put LINK_DIRECTORIES in cmake .. that was it :)

That was exactly the problem, thank you. I was using cmake and not properly
linking directories. Now I just need to figure out how to extract the points
that need to be in the point cloud ... any advice? 

Thanks a lot,
Corina

Typically you'll need to maintain a stack of the state (that you're
interested in) during parsing.  You should be able to identify nodes of
interest to you in on_node_start; and then fields of interest in
on_field_start.

I extracted the points so far but I still need the faces(so I can add even
more points) .. and for that I need the type of coordIndex but somehow I
can't figure it out...

Thanks,
Corina

Erm... I would suggest consulting the specification on such matters.

It's MFInt32.
