You'll have to install the developer's version to get the headers.  If
this happens, and the code lives under /usr/local/mozilla, you can add
/usr/local/mozilla/include to these environmental variables:

C_INCLUDE_PATH -- for the C compiler
CPLUS_INCLUDE_PATH -- for the C++ compiler
OBJC_INCLUDE_PATH -- for the Objective C compiler

All the compilers in GCC *should* see them then.  If there are any
libraries included with the code, put /usr/local/mozilla/lib
in your LD_LIBRARY_PATH or /etc/ld.so.conf and run 'ldconfig' as
root.

I've never encountered a person who hasn't been forced to use the
--nodeps option with RPM from time to time.  I don't prefer to use
it, myself.  Just my $0.02 USD...

Hopefully. I will definitely be looking at that issue in the context of
the new set() and get() methods.

Braden,

Does this mean that the "route event to PROTO" bug will be
resolved in 0.12?

crazy!

im using mandrake 7.2 here and the libstdc
is all screwy

i thought i could get away
doing a rpm --nodeps

but it dont like it

sigh...
i wish there must be an easier path to compile here

[Openvrml-develop] Looking down the road

[Braden M. <br...@en...>]

Here is a bit of a roadmap for the next few of OpenVRML releases.

For 0.12:
* Change to using std::string instead of char * most places.
* Implement set() and get() methods for setting eventIns and getting
  eventOuts for all nodes.
* Refcount VrmlNamespaces with a smart pointer.
* Implement dynamic loading mechanism for Script node language binding
  components and finalize the API for these components.
* Preliminary Java support for the Script node.

For 0.13:
* New node component architecture.
* Functionally complete Script node Java support.
* VrmlMatrix support for JavaScript.

For 0.14:
* Asynchronous I/O.

Obviously, the further we look into the future, the hazier things are.
And of course, this is all subject to change. But per this roadmap, the
API should be mostly complete with the 0.14 release. The one component
that may remain in flux is the Viewer. This will receive attention as
the node implementations are tweaked for conformance.

The biggest change in all this is the new node component architecture.
It will allow the library to be extended with new nodes *without*
recompiling the library. New nodes can be added as C++ shared objects
*or* as VRML PROTOs. I'll be posting more information about this as the
work for 0.12 nears completion.

The header file is typically included in a "mozilla-devel" package if
you use RPMs. mozilla.org, unfortunately, has done a less-than-exemplary
job of establishing standard installation locations for things like
header files, and OpenVRML's configure script is biased toward the
decisions Red Hat has made for its RPM packages. Patches to support
other schemes are welcome, as long as they don't break what's currently
working.

i think i found an error in the config log


it looks for mozilla/jsapi.h

no such file or directory!!

which i cant see anywhere in the mozilla install dir

so im cvs in the mozilla/js again to enable that

did this and im still getting cant find libmozjs.so

whats up?

i tried

ldconfig setting to /usr/local/mozilla

./configure --with-mozjs=/usr/local/mozilla

then i tried linking to libmozjs.so from /usr/local/lib

then i tried copying over the libmozjs.so to there and to /usr/lib too

the configure script cant find it!!

what could i be doing wrong?

The easiest way is just to install Mozilla.

"libjs" is the name of the library created by the "reference build" for
SpiderMonkey. The Mozilla build, however, creates "libmozjs". There's no
technical reason that we couldn't build against "libjs", other than the
fact that OpenVRML's build scripts aren't currently set up to
accommodate this.

Yes, the docs suck. But since I'm working on rearchitecture, improving
them is not a high priority. Most of the stuff I've touched in the API
now has Doxygen comments, though that's really only a first step toward
decent documentation. Sane docs will be a high priority once the new
node architecture is in place.

Re: [Openvrml-develop] installing spidermonkey on linux

[clayton c. <dr...@sm...>]

one question:

how does one install spidermonkey libs


i also see a prob with openvrml is always looking for libmozjs.so
when the lib , from js-1.5-rc3a is called libjs.so

is this true?
or am i missing a step with the install?

im assuming im just supposed to cp LINUX_All_OPT.OBJ/ to /usr/local/lib/
??


any help appreciated

[Openvrml-develop] Are there any good examples out there?

[Diana G. <dia...@nr...>]

Ok, so I have openVRML and I have spent the last two days reading over the
code and trying to figure it out.
The documentation is horrible!  But on the otherhand the code seems good.  I
think documentation should become a priority, the code is too deep for just
tracing your way through it.

Anyway besides the point, I would like to use these libraries to program
with VRML.  Almost like using performer.  I want the ability to trace the
scene graph, manipulate nodes, and add in features.
Does anyone have any example programs of using these libraries for anything
besides a viewer?

Thanks in advance for your help.

Re: [Openvrml-develop] matrix to transform

[Nigel S. <ni...@ni...>]

Peter,

There is some code in a volume of Graphics Gems
for decomposing a matrix into scale, translate,
rotate and shear components.  It would need some
adaptation from rotating about the x, y and z
axes....  An LGPL implementation is available in
my GLT library:

http://www.nigels.com/glt/

Cheers,

Just use VrmlMFNode::getElement().
