[This does not appear to be related to the previous message in this 
thread; please start new threads as appropriate.]

openvrml::rotation and openvrml::quatf (see basetypes.h) provide 
conversions between the conventional VRML axis+angle format and 
quaternions. There are also constructor functions to create an 
openvrml::mat4f from a rotation or a quatf and functions to get a 
rotation from a mat4f. However, there is no code in OpenVRML that deals 
with Euler angles.

Can anyone tell me where I should be looking for 3d math and matrix utilities?

	for example, is there a method for converting  Heading Pitch Roll angles to SFRotation?

	NPS had a java class to do this... 
just wondering if we had a C++ class that could also do conversions (not just quaternion slerping)

	
thanks and best regards,

OpenVRML doesn't know about NurbsSurface. (It could probably be
implemented by twiddling the existing support for the X3D
NurbsPatchSurface node; however, note that OpenVRML is currently only
capable of constructing scene graphs with these nodes--rendering them is
not implemented.)

The assertion failure shouldn't happen; and in 0.16.3, it doesn't (for
me). You don't say what version of OpenVRML you're using.

[openvrml-develop] openvrml-player in CVS

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

openvrml-player, the stand-alone viewer, is in CVS and is in a
reasonably usable state. I encourage folks to check it out and take it
for a spin; building it requires libgnomeui and libcurl. This will go
into the 0.16.4 release.

With regard to that release, there are a few more things I'd like to fix
before putting it together; significantly bug 1521627 (JPEG decoder
can't read from an arbitrary stream). But I hope to get it out in two or
three weeks.

That's the problem.

According to the documentation, the GOption stuff was added in 2.6. I'll 
tweak the check in configure to make that version a minimum requirement.

choking on them. It's the GOptionEntry bit that's got
me stumped.

[openvrml-develop] OpenVRML needs a logo

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

openvrml-player is just about in a state where I'll check it in. This is
a stand-alone application that will be part of the default build
configuration. And once installed, it will be accessible through a cute
little icon in the desktop menus.

The "cute little icon" is where things kind of fall apart for me.
Creating digital art is not a skill I have honed; I could *really* use
the assistance of someone who's good at this sort of thing.

I'm looking for a logo that will be applied to all of OpenVRML--not just
the player. Obviously, it should iconify well--ideally down to 16 pixels
(though perhaps a recognizable variant of the design could be used at
really small sizes). I don't think I'm looking to replace OpenVRML's
existing textual logo (as displayed on the Web site); I'm thinking the
graphical logo would complement this.

So if someone within earshot of this list is good at this sort of thing
and would like to help, please contact me--either on- or off-list. Or if
you know someone not on this list who has a hand for these things and
who might like to help, feel free to forward this to them.

I've struck out in my attempts to reproduce this; the release build
works just fine for me.

Taking a closer look at the error messages, it looks as if the compiler
isn't finding the correct openvrml-gl-config.h. The correct one is
ide-projects/Windows/VisualC8_0/OpenVRML/openvrml-gl/openvrml-gl-config.h. It looks like the compiler may be finding one you generated from configure to build with gcc.

FYI, gcc's -Woverloaded-virtual is good for catching this kind of thing.

It looks like you are probably missing some preprocessor definitions.

Are you using the project files included in the distribution, or ones
you've cooked up yourself? If the latter, I suggest you compare your
project settings to what's included in the distribution. If the former,
I can take a look at this tomorrow.

Re: [openvrml-develop] Preventing rendering of background

[Philip L. <ph...@ed...>]

Solved it.. the insert_background method was being subclassed in the  
old code, but as the prototype for insert_background has changed  
between OpenVRML 0.14.3 and now, the subclassed method was not being  
called. Changed the prototype and now it works again.

Thanks.

I'd imagine the simplest way to do this is to inherit
openvrml::gl::viewer and override insert_background with an
implementation that does nothing.

[openvrml-develop] Preventing rendering of background

[Philip L. <ph...@ed...>]

Hi all,

I have what is possibly quite a simple problem, but one which has me  
a little baffled.

I have been updating some older code inherited  (using  
openvrml-0.14.3) which draws VRML on top of other pre-existing pixels  
in a window.

Updating this code to OpenVRML-0.16.3, object backgrounds are always  
drawn, overwriting the pixels that I need to display the VRML on top of.

Now that I look at it, I can't figure out how the backgrounds of the  
models were suppressed in the older code.. there is certainly nothing  
explicitly commented as such.

Is there some simple way to suppress drawing of backgrounds, in  
either the browser or viewer?

Cheers,

Phil.

[openvrml-develop] ANN: OpenVRML 0.16.3

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

OpenVRML 0.16.3 is now available.  The distribution can be obtained
from

  <http://downloads.sourceforge.net/openvrml/openvrml-0.16.3.tar.gz>

OpenVRML is a C++ runtime library for VRML97 and X3D worlds.  It is
capable of reading and displaying VRML/X3D; it can be used for creating
loaders, file converters, and VRML/X3D browsers.

OpenVRML includes a Mozilla browser plug-in.

You can find OpenVRML on the Web at

  <http://openvrml.org>


New in OpenVRML 0.16.3:

- Changed openvrml-gtkplug only to expect an initial stream when
  passed the --initial-stream argument.

- Fixed deadlocks in openvrml-gtkplug.

- Fixed a bug in openvrml-gtkplug that caused it to consume 100% of
  the CPU.

- Fixed relative URI resolution on Windows.

- Mozilla plug-in now registers itself as a handler for
  model/x3d+vrml.

- Fixes for compiling on Mac OS X PPC.

- Fixes for compiling with Apple's OpenGL framework.

- Fixes for compiling with Microsoft Visual C++ 8.0 Service Pack 1.

[openvrml-develop] 0.16.3 on the way

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

I had hoped to have the stand-alone viewer ready for 0.16.3; but it just
isn't progressing quite fast enough. There are some really useful fixes
on the OpenVRML-0_16-BRANCH now: mainly the fixes for building on Mac OS
X, a fix for the problem that caused openvrml-gtkplug (and thus the
Mozilla plug-in) to consume 100% of the CPU, and now fixes to build with
Visual C++ 8.0 SP1.

So I'll be putting together 0.16.3 in the next few days. The stand-alone
viewer will have to wait for 0.16.4.

[openvrml-develop] FW: [osg-users] Has anyone tried making a VRML loader using OpenVRML?

Hello,

If anyone is interested....

Yes, I have such loader. It needs to be updated to the latest OSG and new
OpenVRML (i.e. it doesn't work right now). It is not as full-featured as the
Coin-based loader, it can only load meshes and textures, though.

Well... It will be another example of using openvrml-gtkplug. It will
also be a reasonable example of how to integrate libcurl with the
GLib/GTK+ main loop. But it will offer no respite from the relatively
complex implementation of openvrml::resource_istream in
openvrml-gtkplug. In other words, it won't be of too much help for
someone who, for example, wants to learn how to use libcurl with
openvrml in the same process.

So openvrml-player won't obviate the need to extend the sdl-viewer
example to use libcurl (in order to show people how to do that).

Great, this will be really useful also as a reference check when writing 
other viewers using openvrml without having to set up the MOzilla stuff.
