Well, pretty much all of the other PLIB libraries depend on SG - so if
you have SSG, PUI or FNT code then you're already using SG - you just
don't know it.

There is a Quaternion test in the PLIB examples package.

What I guess I was concerned about was whether this business of
debug code generation was something that was defined in the '.dsw'
file - and therefore something that we need to fix.

I'm not Windows person - so I don't understand the subtlety of this.

However, I'm planning on doing a 1.8.3 release of PLIB today and if
changes are needed to the Windows build mechanism, I'd like to get them
in ASAP so they'll be included in this release.

  It looks like the sg lib is built using debug code generation while
the rest is built with multi-threaded debug code generation.  Double
check the build settings for your libraries and projects.  If they are
all ok then you could try putting libcd.lib on the ignore library list

[Plib-users] FW: PUI font

[Clay, B. <bc...@ba...>]

3rd try.  The messages never get to the reflector

-----Original Message-----

Subject: PUI font


After a couple of false starts on my part I finally got PUI to work with
the Blue Marble Viewer (BMV).  It will open many doors to usability.

Because of the internal workings of BMV I have to used PUI without GLUT
which isn't a big problem.

There is however one remaining problem.  My first PUI app was a network
based controller to control the BMV scene.  This one used GLUT and had
great contrast.

The GUI created for BMV without GLUT doesn't have the same contrast nor
apparently the same fonts.

I have attached 2 images.  The bmv_cntrl.jpg is the with GLUT app and
the other jpg is from Blue Marble.  It looks like I am restricted to
using black text without GLUT because that is the only color that is
clear enough.

In the bmv_cntrl program I did not specify a font (used the default
font. There dosen't seem to be any difference if I specify one with in
BMV or not.

I tried
			puSetDefaultFonts(PUFONT_8_BY_13,
PUFONT_8_BY_13);
and
			mButtonFont->load(fontName.c_str());
			puFont times_medium(mButtonFont, fontSize);
			puSetDefaultFonts(times_medium, times_medium) ;

And
			puFont times_medium();
			puSetDefaultFonts(times_medium, times_medium) ;

None of them seem to clear up the problem.  The font size and type
changes on screen so it does appear to be loading the font just not
drawing it clear with any color but black.

Any thoughts would be greatly appreciated.

Yeah - don't install Mesa - get the nVidia drivers

I suspect that you have some kind of sound deamon
installed - several windowing systems install them.
They sit there, hogging the sound card, mixing incoming
audio from the windowing system and locking out other
programs.

[Plib-users] sound in plib

[Guihua Y. <sha...@ya...>]

Hi, 

I installed plib 1.8.2 in my laptop(dell inspiron
8200). The OS is  linux redhat 9.0, also I installed
mesa 6.0( possibly I shouldn't install this since I
have Geforce 4, which has hardware support for
opengl), freeglut. Everything works fine, except the
sound.

When I play a sound file in linux, it works fine. But
when I ran plib 1.8.1 example and try sound example, I
got this error: 

slDSP: open: Device or resource busy
WARNING: slScheduler: soundcard init failed.

What could be the reason? Should I do any other
setting to make the sound work?

Thanks.

Sharon

Well, I guess so.  You can certainly run PLIB stuff within FLTK windows (there is an example of how to do
that in the 'examples/src/pui/fltk_demo').   However, to mix FLTK windows with windows made with another
windowing toolkit seems like you're getting into dangerous territory!

I'm not aware of any such limits...I guess this is a question for John Fay.

> 3 when i load the 3ds object if it use texture i need to add it is there an option to

If it uses bmp or rgb images, PLIB will load them automatically.   If you want to use
some other image file format then you'll need to catch the filename and load the texture
yourself.

You need to write a callback function to create the ssgSimpleState:

Before you start loading files:

    ssgLoaderOptions *loader_opts = new ssgLoaderOptions () ;
    loader_opts -> setCreateStateCallback ( getAppState ) ;
    ...set other loader options maybe...
    ssgSetCurrentOptions ( loader_opts ) ;

Then write 'getAppState' like this:

   ssgState *getAppState ( char *fname )
   {
      ...fname is the name of the texture map - you load it and
      attach it to an ssgSimpleState...
   }

Well, you can get gl.h and other GL headers from www.opengl.org somewhere.

However, 'libGL.so' utterly has to be there - that *is* the interface and if it's
not there then no OpenGL programs will work.

Probably, you have the 'back end' part of the OpenGL driver that X uses installed
but don't have the 'front end' part.   I'm not really familiar with ATI cards so
I don't know how it works.  Probably, this is something tied up with the DRI stuff.

Sorry I can't help.

However, it's safe to say that this isn't a PLIB issue.  There isn't an OpenGL
program on the planet that doesn't need libGL.so!

Re: [Plib-users] Where does plib look for gl.h?

[Darrell B. <da...@du...>]

I've just removed all GL directories and libGL* files from my system but 
now I have a bit of a problem. When I install my ATI drivers it doesn't 
come with any gl.h files or libGL* files. It just has a file called 
glxATI.h. Which, incidentally, is installed in /usr/include/GL! I tried 
to install MesaGL but that failed.

Any ideas?

Darrell

Re: [Plib-users] Where does plib look for gl.h?

[Darrell B. <da...@du...>]

Thanks for your help. I wasn't aware of their being a standard location 
so I apologise but it's really not me you should be arguing with. I'm 
using Gentoo Linux and the official ATI drivers and as because of this 
the location of the files is defined by the person who created the 
package. I am going to find out whether it's a problem with Gentoo's ATI 
driver package or the one that ATI deal out and will kindly ask that 
they sort it out. I am thinking about removing all OpenGL libs and 
headers from my system and starting again.

I'm very unhappy with Andy and the AC3D situation.   I purchased a copy
of AC3D some years ago (it's practically the only piece of non-free softw=

I have on my home machine).   It came with 'lifetime' free upgrades.

Recently, Andy has started a company to sell AC3D - and he claims that as=

a result that contract is null and void and if I want an upgrade, it's go=

to cost me money.

For that reason, I will not upgrade to the new AC3D - and I recommend tha=
t
nobody else does either.

Hence, you won't be suprised to hear that I'm reluctant to support the ne=

AC3D file formats.

We will NOT upgrade the AC3D loader for PLIB until/unless the AC3D people=

honor their responsibilities to their customers.

Those are *all* incorrect!

   /usr/include/GL/gl.h

...that's a part of the OpenGL standard for Linux.  Most other OS's
put it somewhere like that too.

I worked on the committee that decided this.

OpenGL doesn't have to be a part of X11/X11R6/xfree - there are new
cellphones and PDA's that run Linux and have OpenGL implementations -
but which DON'T run X.  For those systems, it would be nonsensical to
put gl.h in any directory with X11/X11R6 or xfree in it's path - and
since we'd like all OpenGL programs to only have to look in a single
place, it should be in a system level directory.   /usr/include is
where these things belong,   /usr/include/GL is the standard.

Please stick to it!

> Where does plib look for gl.h because I can create a symlink to the 
> location.

PLIB looks in /usr/include/GL/gl.h - but if it can't find it there, it
goes on to looks in /usr/X11/include/GL/gl.h. That's because some older
Linux distro's (incorrectly) put GL in the X11 tree.

FYI:  The library for OpenGL should be in /usr/lib/libGL.so - and nowhere else.
The GLU, and GLUT/freeglut libraries should be in the same places as OpenGL itself.

It's a very bad idea indeed to allow your system to get polluted with copies of
things like this because when you upgrade something, you are very unlikely to
catch all of the copies and you'll find some programs picking up old copies.

That's very hard to diagnose - so I *STRONGLY* recommend that you do a 'find'
on gl.h and libGL.so and delete all of the copies that are in non-approved
places.

hi

1 can i use fltk & fluid to add one more window to code that wrote in PLIB??
  if i can use it how can i do it? i know i need to add to project->setting the fltk definition but when i compile it isn't work?

[Plib-users] AC3D loader problems

[<fli...@ba...>]

I had a little conversation on the new AC3D Format wirh Andy Colebourne.
Here is was he wrote to me (see also
http://www.ac3d.org/forum/viewtopic.php?p=3D1824#1824 )


I had a quick look at the plib code. In ssg/ssgLoadAC.cxx:=20

Code:=20
static int search ( Tag *tags, char *s )=20
{=20
  skip_spaces ( & s ) ;=20

  for ( int i =3D 0 ; tags[i].token !=3D NULL ; i++ )=20
    if ( ulStrNEqual ( tags[i].token, s, strlen(tags[i].token) ) )=20
    {=20
      s +=3D strlen ( tags[i].token ) ;=20

      skip_spaces ( & s ) ;=20

      return (*(tags[i].func))( s ) ;=20
    }=20

  ulSetError ( UL_FATAL, "ac_to_gl: Unrecognised token '%s'", s ) ;=20

  return 0 ;  /* Should never get here */=20
}=20


replace:=20
Code:=20
  ulSetError ( UL_FATAL, "ac_to_gl: Unrecognised token '%s'", s ) ;=20


with:=20
Code:=20
ulSetError ( UL_WARNING, "ac_to_gl: Unrecognised token '%s'", s );=20

replace ' Code:=20

That may fix it.=20

[Plib-users] Where does plib look for gl.h?

[Darrell B. <da...@du...>]

I can't get plib to find gl.h and I know for a fact that OpenGL is 
installed because XScreensaver compiled and works fine with GL 
screensavers. When I run "find / -name gl.h" this is what I get...

/usr/lib/opengl/xfree/include/GL/gl.h
/usr/lib/opengl/xfree/include/gl.h
/usr/X11R6/include/GL/gl.h

Where does plib look for gl.h because I can create a symlink to the 
location.

Michael Wessels wrote:

Write a function like this:

   ssgBranch *process_userdata ( char *data )
   {
     if ( data == NULL || data [ 0 ] == '\0' ) return NULL ;

     if ( strncmp ( "Tribune1", data, strlen ( "Tribune1" ) ) == 0 )
     {
       ssgBranch *b = new ssgBranch () ;  /* ...or whatever you want this node to be */
       /* whatever you need to do here */
       return b ;
     }

     return NULL ;
   }


Sometime after ssgInit() but before you load your model:

   ssgLoaderOptions *loader_opts = new ssgLoaderOptions () ;
   loader_opts -> setCreateBranchCallback ( process_userdata ) ;
   /* You may wish to set other loader options here */
   ssgSetCurrentOptions ( loader_opts ) ;

...then just load your model in the usual way and whenever SSG
needs to create a branch node, it'll call your 'process_userdata'
function with the comment as the parameter.   If this is a 'special'
node, then you create the node and return it as the result.  If it's
not special then just return NULL and the loader will do something
appropriate.

Re: [Plib-users] Identifying objects after loading an AC3D- modell

Hi Steve,
in my '.ac' file I have the comment field "Tribune1". How can I tell the
PLIB loaders to call a callback function in the application when they find
this comment field ?
Can you give me a strip of code-lines ?

Yes.

All PUI widgets accept 'user data':

    puObject::setUserData ( void *data ) ;
    void *puObject::getUserData () ;

...or you can read the legend or the label:

    char *puObject::getLegend () ;
    char *puObject::getLabel  () ;

Menu callback:

I'm setting up a menu and need to use the same callback for several of the 
menu items and have the callback figure out which one was selected.

Is there anyway to get the string and/or value that was selected in the 
menu or submenu?

The SSG base class has:

    print ( FILE *fd ) ;

So use:

    root_node -> print ( stdout ) ;

Depends on which windowing library you are using.

Our new built-in 'PW' windowing system only supports one window - so don't use that.

However, if you use GLUT, you could copy the example in plib/examples/src/pui/complex.cxx - it opens three
windows.

That means the source of PLIB and any changes you might have made to
it...not to your application.  That's a crucial distinction

In order to use LGPL'ed code you have to make sure the end user can
re-link your application with new versions of PLIB.
