Well, what I have is not so general so to include in a plib distribution.
I'm developing a flightgear grafical starting program and I have builded
some widget classes for this purpose. But I think that, a page which
provides an ordered list with a small description and snapshot of user
provider classes could speed development time of programmers, avoiding to
construct a class which someone else builded (or a class which is close to
those the programmer needs).

Starting with the node returned by the loader, you
can say something like:

 void extract_vertices ( ssgEntity *node )
 {
   /* WARNING - RECURSIVE! */

   if ( node -> isAKindOf ( ssgTypeLeaf () ) )
   {
      ssgLeaf *l = (ssgLeaf *) node ;

      ...extract the vertices from 'l'...
   }
   else
   if ( node -> isAKindOf ( ssgTypeBranch () ) )
   {
     ssgBranch *b = (ssgBranch *)node ;

     for ( int i = 0 ; i < b->getNumKids() ; i++ )
       extract_vertices ( b -> getKid ( i ) ) ;
   }
 }

It's a *little* more complex than that because there could
be ssgTransform nodes in the heirarchy - you'd have to
accumulate the matrix transforms to know how to position
the vertices you get out of the leaf nodes beneath.  Also,
you need to think about what you want to do with ssgSelector
nodes.

[Plib-users] plib class repository

Is there any user-defined class repository for plib?

Yes - of course it's possible.  There are lots of calls to any kind of
ssgLeaf node to allow you to access the vertices, normals, texcoords
and colours.  Read the documentation for ssgLeaf, ssgVtxArray, etc.

*MANY* (actually, probably *ALL*) of my games have a need to occasionally
delve into the vertex structures of ssgEntities.  Just take a look at
Prettypoly for example - it is a complete 3D modeller written around
SSG - you can drag vertices around with the mouse, mess with their
textures coordinates, etc, etc.

So - you are mistaken - it is a primary design goal of SSG that it does
not "hide" things from the application program.

You shouldn't need to do that (and if you do...beware of the LGPL...if
you use even a small part of our loader code in your actual game code,
you could have to license the entire game under LGPL).

OK - no problem - just load the two versions of the model into
separate scene graphs - use one for ssgCullAndDraw, use your own software
to traverse the tree structure of the other to extract the vertex and
polygon data for passing to the collision detection library.

You ask SSG for the OpenGL texture map handle (use ssgTexture::getHandle()),
then you can use OpenGL to ask about the texture using glGetTexImage(...)

SSG doesn't store it directly because OpenGL does.

No - but you can use Mark Kilgard's mktexfont program to make TXF font textures
from any font that X-windows can render - so I presume you could convert TrueType
fonts into TXF and render them that way.

If you were thinking of getting all the rescalability and general niceness of
Truetype fonts then FNT isn't really the right library for you.  Try GLTT.

There are several problems with doing this in FNT:

  1) Patent/copyright bullshit.  The TrueType algorithms are patented
     and I don't want to get into that nonsense.

  2) It's almost impossible to render TT fonts *efficiently* in OpenGL.
     GLTT does a reasonable job - but it's probably a hundred or more times
     slower than FNT.

We are already back in third place - only three votes away from getting

[Plib-users] (Again) accessing vertex infos of a loaded model

[Filippo Di N. <fil...@km...>]

I would like to load a model created with a 3d app into an ssgEntity and
then access the vertex info of it, from what I can understand it's not
possible... seems I'll have to steal the loader source code and insert
it in my little game.
I need to access vertex infos because I want to try a collision
detection library that needs vertex infos of a model.
I would like to use a detailed model for the graphics, and a much lower
resolution model to load into the collision detection object.
Any idea of how I can use PLib for this task without having to steal a
bunch of code from it?

Thanks to everyone!

[Plib-users] dimensions of a texture?

[Albin H. <gat...@ti...>]

Is there a way to get the dimensions of a texture stored in a ssgTexture?

I want the height and width, in pixels, of a texturemap.

If not, is there a reson why this information, used when loading a texture, 
is not stored?

Another thing, has anyone done any atempt to modify the fnt library to load 
truetype fonts?

[Plib-users] Well, I guess PLIB is not the most popular :-(

[Steve B. <sjb...@ai...>]

It looks like a massed vote from the OpenInventor and OpenSceneGraph teams
wiped out our chances of being "Best Scene Graph" over at VRsource magazine.
(http://www.vrsource.org).

Currently:

OpenGL|Performer      14.29 % (36)
Open Inventor(TGS)    28.97 % (73)
OpenSG                11.51 % (29)
OpenScenegraph        23.02 % (58)

WorldToolKit           0.40 % (1)
Others                 3.57 % (9)

Whilst I might concede that Performer, OpenSG and OpenSceneGraph are possible
candidates, there is NO WAY that anyone could consider the outmoded and S-L-O-W
Inventor scene graph in any way the best!

Yes - but...

CullAndPick is a special interface I put in there for PrettyPoly's
selection mechanism - it's not really intended for general use and isn't
at all easy to use.  It's also not documented.

I suggest that if you really want to use it, you examine the PrettyPoly
source code at http://prettypoly.sf.net

Yes.  Well, go to the main www.sourceforge.net site and look at the
'Contact SourceForge' link - click on 'staff' and you'll get here:

  http://sourceforge.net/docman/display_doc.php?docid=6047&group_id=1

From there you can email any of the six or so people that run SourceForge.

According to this post to the FlightGear list I am afraid it might be a
couple
of months before this policy is changed
http://www.geocrawler.com/lists/3/SourceForge/11853/25/6751895/

FWIW - There is also a clue as to perhaps the why of this policy change

I would have thought that every list owner/moderator (and even the
users) would be able to justifiably contribute to the discussion at
any time.  Of course it won't be read till the start of next week, but
that is still a lot sooner than the 16th.  I may be naive, so I ask:

I'm sure polite mail to someone @lists.sourceforge.net would get percolated

Re: [Plib-users] Newbe Question

[Dave M. <dp...@ef...>]

I got started with PLIB by looking at
plib/examples/src/ssg/tux/tux_example.cxx ; the function of interest is
sgSetCoord()...

void sgSetCoord ( sgCoord *dst, const SGfloat x, const SGfloat y, const
SGfloat z,
  const SGfloat h, const SGfloat p, const SGfloat r ) ;

This is used in tux_example.cxx like this

  sgSetCoord ( & campos, 0.0f, -5.0f, 1.0f, 25.0 * sin(frameno/100.0), 0.0f,
0.0f ) ;
  ssgSetCamera ( & campos ) ;

Playing around with this, you should be able to implement your flying code.
You can also look at the viewer example which lets you zoom and orbit a
fixed point.  You can also use quats or build matrices yourself...

http://web2.airmail.net/sjbaker1/matrices_can_be_your_friends.html

Manipulating direction vectors and quats have some advantages you'll
appreciate later like interpolation and immunity to gymbol lock.  Camera
systems can get very sophisticated and complicated, especially in collision
avoidance, but that should get you going.

I have no idea - I don't have much to do with the Windoze
side of the build mechanism.  I know that people do build
it under MSVC - so this *should* work OK.  I can't imagine
that SourceSafe should be involved.

Well, I design flight simulator software as my full-time
job - so I could perhaps help with any specific questions
you have.

Also, you might want to note that the FlightGear OpenSourced
flight simulator project (www.flightgear.org) also uses
PLIB - their mailing list (which has a significant overlap
with the membership of this list) is a *great* place to ask
questions about flight simulation.

I'm not aware of any online tutorials - it's rather a large
subject area and any comprehensive tutorial would consume
a dozen books.

[Plib-users] Newbe Question

[Red <red...@ya...>]

 Hey, I just downloaded plib-1.4.2. I'm using VC++ 6,
and when I try to open plib.dsw VC asks me for a
source safe login. Does anybody know what's going
on???

Also me and some friends want to make a sci/fi flight
sim. We pretty much understand what it takes to make
an fps, but have no idea where to look for tutorials
on flight sims. Does anybody have any suggestions???

Thanks

Yes - it does seem to have been left out of the distro.

I wonder how come nobody noticed before?

I'll email a copy to Marvin - privately.

[Plib-users] Re: Weird errors using ssg.h

[Steven W. <st...@ba...>]

Nevermind - I didn't use a *.cpp extension and the C++ headers in plib
were being parsed by the gnu C compiler, not the C++ compiler.  8(

My bad.  8)
