[openvrml-develop] How to get the bounding sphere with openVRML?

[Joan T. L. <jt...@ho...>]

Hello,

I'm new with OpenVRML. I would be greatful if someone can explain me how I have tu use the OpenVRML API to calculate the bounding sphere of a VRML object.

Thanks in advance

Resizing, minimizing/restoring doesn't make things appear. When I tried
snoman.wrl and it appeared normal, after resizing the window, I could only
see his arm...4 times (it was still animated).
When the console shows the inconsistencies, the viewer freezes. The output
window of Visual Studio shows "First-chance exception at 0x7c812a5b in
sdl-viewer.exe: Microsoft C++ exception:
boost::spirit::parser_error<openvrml::vrml_parse_error,boost::spirit::position_iterator<boost::spirit::multi_pass<std::istreambuf_iterator<char,std::char_traits<char>

I added the libjpeg libraries, the textures are displayed correctly now.

Sounds like there might be a redrawing issue. Does resizing the window 
make things appear? How about minimizing/restoring?

IIRC, the project files that are included with the distribution aren't 
set up to build with libjpeg; you'd need to build libjpeg and change 
that if you want to see JPEG textures. PNG textures should work, though, 
assuming you're building with libpng.

Oops, my bad...I didn't set the right working directory. The viewer now only
sometimes shows the vrml-object. I get a blank console and viewer window
most of the time (say 16 out of 20). Sometimes the console shows only some
inconsistencies in the wrl-files and the viewer stays blank. And once in a
while (say 1 out of 20) I can view an object (no textures though). Any ideas
on this behaviour?

How are you invoking sdl-viewer? It only accepts valid URIs. And in the
case of sdl-viewer, it only accepts file (or relative) URIs.

You were right about that, I had the order mixed up, now I can build
everything.

However I can't seem to open wrl-files in the included sdl-viewer (or an
other program which uses openvrml). Every wrl-file I try to open I get the
console message:
"unrecognized error during resolution
no alternative URI could be resolved"
And in my output-window: "First-chance exception at 0x7c812a5b in
sdl-viewer.exe: Microsoft C++ exception: openvrml::no_alternative_url at
memory location 0x0246fb58.."
I can't exactly trace back in the code where this error occurs, so I hope
you have an idea?

That, apparently, is sufficient then. (In the absence of the "using"
declaration, you should need to qualify uses of "child_node" with
"openvrml::"; but if the compiler accepts the code without that, I don't
see a reason for you to care about that at the moment.)

I don't see this with the project files from the OpenVRML distribution.
Perhaps you modified the "Additional Include Directories" in the project
settings such that the compiler can no longer find "openvrml-config.h"?

Thank you for your fast reply, I changed to the boost 1.35 libraries and now
use the official distributions of png and ft2. After this I still had one
error, the last one I mentioned in my previous post. (vrml97node.cpp(27736)
: error C2885: 'child_node': not a valid using-declaration at non-class
scope).

	openvrml::mfnode::value_type::const_iterator iter =
		current_children_.value().begin();
	for (; iter != current_children_.value().end(); ++iter) {
		using openvrml::child_node;
		using openvrml::node_cast;
		child_node * const child = node_cast<child_node *>(iter->get());
		if (child) { child->render_child(viewer, context); }
	}

I wasn't sure what to do with, so I commented 'using openvrml::child_node;'.
After this, I could build everything. Except the release version of
openvrml-gl (debug builds fine). When I try to build the release-version, I
get quite some errors, most of them with OPENVRML_API or OPENVRML_NOTHROW in
the code.
An example:
	read_write_mutex.h(30) : error C2059: syntax error : 'string'
	read_write_mutex.h(30) : error C2146: syntax error : missing ';' before
identifier 'read_write_mutex'
	read_write_mutex.h(30) : error C2470: 'read_write_mutex' : looks like a
function definition, but there is no parameter list; skipping apparent body
	read_write_mutex.h(30) : error C2059: syntax error : '{'
points to:
	class OPENVRML_API read_write_mutex : boost::noncopyable {
		boost::mutex mutex_;
		boost::condition read_, write_;
		std::size_t readers_active_, readers_waiting_, writers_waiting_;
		bool writing_;

Any idea what I should do to get rid of these errors? And should I have
commented the line in vrml97node.cpp?

Thanks in advance,

My mistake. I thought it used print, but you're right.

So are you unable to get "print" to show anything from openvrml-player?

technologies, such as (but not limited to) X3D, VRML, COLLADA, Croquet, MPEG4, MPEG7, Java3D, and Canvas3D. The symposium will also
focus on recent trends such as interactive 3D graphics and applications on mobile devices.

Authors are invited to submit their work (short or full papers) for review by the international Program Committee. Both research and
applications papers are of interest to Web3D 2008. The papers must be innovative and contribute to the advancement of 3D Multimedia
technologies on the Web. Topics of interest include but are not limited to:
	·	Interactive 3D graphics and immersive systems for servers, desktop and thin clients,
	·	High-performance 3D graphics for Virtual Worlds, MMOs, Augmented Reality, and interactive on-line gaming
	·	Animated humanoids and complex reactive characters (e.g. avatars)
	·	Integration and interoperation with 3D Documents and Web/Multimedia technologies, including the Semantic Web
	·	Methods for modeling and rendering complex geometry, structure and behaviors
	·	User-interface paradigms and interaction methods for real-time 3D graphics and virtual environments
	·	Innovative 3D graphics applications for Web/Multimedia in industry, science, medicine, and education

Authors are invited to submit full papers of up to 9 pages (including figures and references) or short papers of up to 4 pages
(including figures and references) in PDF format via the Symposium Submission Site. Papers must be formatted using the document
templates for conferences sponsored by ACM SIGGRAPH. After acceptance, the final revised paper is required also in camera-ready
electronic form. Accepted papers will appear in the Symposium Proceedings, published by ACM Press.

openvrml-player is just a host for openvrml-xembed.  Fedora's
openvrml-xembed links with Firefox's libmozjs.

Are you able to see any console output from using "print" in JavaScript?

Can you see, for instance, the output from generated from moving the
sliders in rotation_toy.wrl (in the OpenVRML distribution)?

OK
I'm not seeing it the terminal...

this is the build included w/ fedora.
ldd shows that its not compiled w/ libjs so maybe that is the problem... ?

Note that you'll need to build boost as well and tell Visual Studio
where to find the libraries.

If you are using Visual C++ 2008 (9.0), I recommend using Boost 1.35.0.
The build system in 1.34.1 doesn't know about that compiler.

I think I've heard of this one; though I haven't built with the DirectX
SDK present.

For these, I generally use the official distributions.  They include
usable project files.

This is fixed on the trunk. (Though it looks like the fix didn't make it
over to the 0.17 branch; I'll address that.)

FreeType changed its function signatures some releases ago.  Either get
a fresher FreeType or set OPENVRML_FT_CONST to an empty string.  It is
set to "const" in the included project files.

For some reason, you need to qualify child_node here:
"openvrml::child_node".

As with the above issue, this is fixed on the trunk.

[openvrml-develop] Building openvrml

[M. v. D. <m.v...@me...>]

I've been trying to build the openvrml-0.17.5 library but I can't seem to
make it work. I'm not sure if this is the right place to post this, but if
not...let me know :)
I already changed and added some things I found on the internet to get where
I am now. I started with the original solution which I downloaded from
sourceforge.
- Added the include files from boost_1_34_1
- Rearranged the include files so the DirectX SDK's come last (because of a
new version of strsafe.h)
- Used the png and ft2build from openscenegraph
- Switched 'public

'public openvrml::node_impl_util::abstract_node<Derived>::template

not sure why, before I switched it, it gave an error)

Now I'm stuck at this error:

I've contributed to the OSG VRML plugin, and I suspect that the main 
issue with the latest OpenVRML distribution is that it adds an 
additional dependency without getting an apparent benefit from it in 
return. The VRML plugin would be the first OSG component to depend on 
boost, and adding this dependency can be a hassle especially on Win32. 
I'm sure that a lot of OSG users do not bother to build the VRML plugin, 
so making an exception for the ones that do use VRML or X3D may be 
acceptable. Let's make it clear that I do not set out the policy on this 
matter. I guess there just isn't a high demand for X3D support. Indeed, 
COLLADA has replaced VRML/X3D as an open exchange format, which leaves 
X3D's application area to be mainly web-apps. As for VRML97, if it would 
show that , for instance, OpenVRML 0.16 is a lot faster than OpenVRML 
0.14 or has otherwise better quality (memleaks, etc) then making a move 
to 0.16 may be worthwhile for sure.

Note that you'll have to add "x3d" or "x3dv" as an extension in de 
osgDB/Registry.cpp as well as fix the 
osgPlugins/vrml/ReaderWriterVRML2.cpp to allow for X3D file extensions.  
Also,  I would like to note that the current VRML plugin is not fully 
VRML97 compliant. In the latest developer release, there is support for 
IndexedFaceSet, Sphere, Box, Cone, and Cylinder.

There are references to BOOST being a problem on other platforms. Don't ask
me why. 

However, you can compile 0.16.x or later in OSG yourself and submit the
plugin.

There were no search matches for X3D on the OSG wiki.

The OSG plugin writers seem to be more interested in collada than X3D.

While I'm aware of OpenVRML's usage in OSG, I'm really not familiar with 
the particulars of it.  If no one chimes in here, you may have better 
luck asking on an OSG mailing list.

Hi all~

I see that openvrml can be used as a loader with openscenegraph
http://www.vis-sim.com/3dsceneBB/viewtopic.php?t=906


does that mean x3dv files too?

How is the mapping / node support once you are in the osg idiom?

it looks to be less than interchange:

Re: [openvrml-develop] ./configure script not finding freetype/fontconfig in OSX

[Hisham <hi...@al...>]

Never mind...I figured it out. pkgconfig was not installed on my
system. A 'sudo port install pkgconfig' fixed the issue. The
./configure script should probably be modified to make that error more
obvious. (I would do that, but I'm a relative newbie and already spent
too much time banging my head figuring this issue out...)

Thanks!

OpenVRML's configure script looks for pkg-config metadata to determine
the availability of FreeType and fontconfig.  These files end in ".pc"
and are generally stored in ${prefix}/lib/pkgconfig.  You may need to
make this directory available to pkg-config by setting PKG_CONFIG_PATH.

If that doesn't help, please post your config.log file.

[openvrml-develop] ./configure script not finding freetype/fontconfig in OSX

[Hisham <hal...@gm...>]

Hi I'm trying to run the ./configure script for openvrml-0.17.5 on Mac
 OS X,  but I get this error:

 "configure: error: fontconfig and FreeType are required for rendering
 Text nodes."

 I've installed freetype and fontconfig via macports, and made sure my
 LDFLAGS environment variable has "-L/opt/local/lib", but I still get
 the error.

 I do have the libraries in /opt/local/lib:

 $ ls /opt/local/lib/*freetype*

 -rwxr-xr-x  2 root  admin  514204 Mar  8 21:43 libfreetype.6.3.16.dylib
 lrwxr-xr-x  1 root  admin      24 Mar  8 21:43 libfreetype.6.dylib ->
 libfreetype.6.3.16.dylib
 -rw-r--r--  2 root  admin  602168 Mar  8 21:43 libfreetype.a
 lrwxr-xr-x  1 root  admin      24 Mar  8 21:43 libfreetype.dylib ->
 libfreetype.6.3.16.dylib
 -rwxr-xr-x  2 root  admin     855 Mar  8 21:43 libfreetype.la


 $ ls -all *fontconfig*
 -rwxr-xr-x  2 root  admin  184752 Mar  8 21:44 libfontconfig.1.3.0.dylib
 lrwxr-xr-x  1 root  admin      25 Mar  8 21:44 libfontconfig.1.dylib
 -> libfontconfig.1.3.0.dylib
 -rw-r--r--  2 root  admin  247424 Mar  8 21:44 libfontconfig.a
 lrwxr-xr-x  1 root  admin      25 Mar  8 21:44 libfontconfig.dylib ->
 libfontconfig.1.3.0.dylib
 -rwxr-xr-x  2 root  admin     967 Mar  8 21:44 libfontconfig.la

 Any ideas?

Ah, great!  This will be really good for me, and I think for other 
people who might be interested in using libopenvrml...
