Re: [Plib-users] Save *.ac Files, File empty

[Michael W. <michael.wessels@z.zgs.de>]

Hi all,

as I know in ppe you can load an *.ac model and can save with a new file-name.
This means, that in ppe the *.ac-loader and *.ac-writer works well.
Can I have more informations about this *.ac-loader and *.ac-writer?

Michael

Probably the problem that Michael has is one I had also and that is
documented in the todo list. Since I get this with more or less all
loaders/writers, I don't think its the .AC loader/writer.
Also note that counting the number of polys returns zero, so its not
that surprising that the AC writer writes out an empty file.

Its funny you bring this up now; The day before yesterday we started a
discussion about this on PPE devel, please look into the archives.
Unfortunately, all of us are fairly confused.

I would guess the aperture is mem space that the AGP may read?
I *think* we have the effect with non-AGP cards as well.

Is there an expert on all the memory types (private, committed
reserved, etc etc) and on mem usage here?

Bye bye,

[Plib-users] A bit off-topic: Mem. utilization

[<ha...@sl...>]

I'm sure this is a frequently asked question, but the glutCreateWindow()
function takes my process memory utilization from 1.2mb to 162mb.

On bootup, I get this:
agpgart: AGP aperture is 64M @ 0xe4000000

So that's about the aperture size times 2, when I start the process.  I
guess I should be checking "glut" docs for this, not this mailing list.  I
figured someone here would know exactly whats going on though.

Hello!
I put the headers and libraries in the proper directory, but it didn't 
work since I tried the new Plib1.3. which works fine.
Now I'm trying to compile FlightGear.
Thanks

Aha!  Your headers are installed in the wrong place.

There is a standard for this (search for "OpenGL ABI for Linux" in Google and you'll find it).

You need (as a minimum):

   /usr/include/GL/glut.h
   /usr/include/GL/glu.h
   /usr/include/GL/gl.h
   /usr/include/GL/glext.h

   /usr/lib/libglut.so  {with optional version numbers)
   /usr/lib/libGLU.so   {ditto}
   /usr/lib/libGL.so    {ditto}

Distributions that install these things in /usr/X11/lib are in violation
of the OpenGL specification for Linux...your should email the Mandrake guys
and complain.

Mandrake will claim that OpenGL is a part of X and so should be installed
in the X11 area - but they are wrong - there are versions of OpenGL that
run without X and /usr/include/GL is the "official" place.

RE: [Plib-users] Save *.ac Files, File empty

[Dave M. <Dav...@dy...>]

When you walk the graph, try just checking for a LEAF instead of particular
type of leaf.

  if ( e -> isAKindOf ( SSG_TYPE_LEAF ) )

The leaf class has everything you need to count triangles and verticies.

There was a little problem concerning the type of leaf
saved (it uses VTables instead of VtxTables) but 
Dave McClurg should have submitted the correction.
May be the use of a more recent CVS image should 
solve the problem.
It worked perfectly (providing you do a flatten
before) with the correction.

[Plib-users] Vertices and Triangles in ssgTransform

[Michael W. <michael.wessels@z.zgs.de>]

Hi Steve,

my intetntion is not to save an object in a *.AC-file. This was only a
test, to see by debudgguing the code in what way the informations of an
object are strored.

I need the information about the vertices and triangles of an object in
my FlightSimulator-programm to calculate shadow.

I am loading the AC-objects with ssgLoadAC in an object of ssgTransform
class.

How can I get the needed informations out of the ssgTransform-object?

Can you help me?

With best regards

Michael

NoNoNo!

You need GLUT 3.7.

Well:

   % which xmkmf
   /usr/X11R6/bin/xmkmf                                                            

...so I guess you are right.  I have no idea why you don't...but
it's OpenSource - so if you don't have it then you can have it - Right?

Alternatively - grab freeglut (URL below in my .sig), it builds with
just the usual './configure ; make ; make install'.

Re: [Plib-users] Having trouble with ./compile

[Martin L. M. <exa...@ba...>]

Hey again.
  Okay, I've determined that I haven't got glut.  I went and got the 
newest stable ver, 3.6, and unpacked it to its own directory.  
Following the linux-specific directions, I set everything up for 
creating a make file... but I don't have xmkmf!  I _think_ xmkmf is 
part of the Xwindows library, so how can I not have this?  
  I realize this isn't exactly in the direct purvue of this list, but 
since you all (most of you) got PLIB to compile, I'm hoping you can 
help me again.
  Thanks for your time!
Martin

[Plib-users] TuxFleet-0.3.2 released

[Alexander R. <a_r...@in...>]

Hi,

I've uploaded the 'newest' version of TuxFleet to my project page
	http://tuxfleet.sourceforge.net

The only changes are a bit of cleanup and a ./configure ; make
process via autoconf, should be easier to compile.

TuxFleet needs plib-1.3.0 by Steve Baker (plib.sourceforge.net) to
compile.

A i386-linux binary is also available.

If you don't mind, please download the source and/or the binary and test
it and send your comments back to me ;-)

If you're able to build a Windows-binary, I'd like to appreciate your
help, too.


Any feedback will be welcome



Alex

[Plib-users] Save *.ac Files, File empty

[Michael W. <michael.wessels@z.zgs.de>]

Hi all,
with the following code I read a *.ac model and try to save it again.

Code:
static int countVertices ( ssgEntity *e )
{
  int count = 0 ;

  if ( e -> isAKindOf ( SSG_TYPE_BRANCH ) )
  {
    ssgBranch *br = (ssgBranch *) e ;

    for ( int i = 0 ; i < br -> getNumKids () ; i++ )
      count += countVertices ( br -> getKid ( i ) ) ;
  }
  else
  if ( e -> isAKindOf ( SSG_TYPE_VTABLE ) )
  {
    ssgVTable *vt = (ssgVTable *) e ;
    count += vt -> getNumVertices () ;
  }

  return count ;
}

static int countTriangles ( ssgEntity *e )
{
  int count = 0 ;

  if ( e -> isAKindOf ( SSG_TYPE_BRANCH ) )
  {
    ssgBranch *br = (ssgBranch *) e ;

    for ( int i = 0 ; i < br -> getNumKids () ; i++ )
      count += countTriangles ( br -> getKid ( i ) ) ;
  }
  else
  if ( e -> isAKindOf ( SSG_TYPE_VTABLE ) )
  {
    ssgVTable *vt = (ssgVTable *) e ;
    count += vt -> getNumTriangles () ;
  }

  return count ;
}

/*
Load Model.ac with plib
*/
static void load_model()
{
 char Data_Path[128];
 char Type_Name[128];
 int Num_Triangles;
 int Num_Vertices;
  test_obj = new ssgTransform ;
  sprintf(Data_Path,"..\\Data\\");
  ssgModelPath   (Data_Path) ;
  ssgTexturePath (Data_Path) ;
  ssgEntity *obj = ssgLoadAC ("cube.ac") ;
//  ssgFlatten         ( obj  ) ;
  test_obj -> addKid ( obj  ) ;
//  ssgStripify        ( test_obj ) ;
  root_scene = new ssgRoot;
  root_scene -> addKid(test_obj);
  Num_Triangles = countTriangles(test_obj);
  Num_Vertices  = countVertices(test_obj);
  sprintf(Type_Name, obj->getTypeName());
  ssgSaveAC("test.ac",test_obj);
}
But the file test.ac is empty without vertices.
Num_Triangles and Num_Vertices gives zero.
Using obj instead of test_obj I got the same result.

Running this part of code in the complete code the cube is visible.

What is wrong?

With regards

Michael

Actaully I've seen some Irix versions of Netscape try the decompression
trick as well (but I think the machine's netscape might had been setup to
pipe the file through gzip and then to disk in the mime-type settings).

Anyway, what version of Winzip are you using?

That's probably because you downloaded it with Internet Explorer which is
buggy.

If you did use IE, what happened is that *it* automagically uncompressed
the GZIP but didn't rename it without the '.gz' extension;

If you rename <whatever>.tar.gz  to <whatever>.tar and then use Winzip
to un-tar it, you'll be fine.

Alternatively, download it with Netscape - which works.

Sounds like you don't have GLUT installed.  You can get
GLUT from www.opengl.org or www.mesa3d.org (and other
places too).

I'm betting that your 'configure' script didn't actually run
properly.

Without GLUT, PLIB won't build and without PLIB, no FlightGear!

Hi,
I'm new to plib and I wanted to compile it to use FlightGear, but when
compiling plib I have the messages:
 GLUT_LEFT_BUTTON undeclared (first use this function)
 GLUT_RIGHT_BUTTON undeclared (first use this function)
 GLUT_MIDDLE_BUTTON undeclared (first use this function)

If I want to compile FlightGear, It doesn't find plib!!
What is the problem.
Thank to answear me

Hi Wolfram,

I have downloaded the source-tar-file as tar.gz but could not extract it
with winzip.

Do you can send me the ppeWalkScene.cxx by e-mail ?

getNumTriangles and
getTriangle. Search the documentation for these.
The good point is that one interface does all cases:
- ssgVtxArray and ssgVtxTable.
- triangles, quads, n sided polygons.
- ignores points and lines.

So, with very little code you can get all faces as triangles.
You just have to walk the scene graph. See for example, in PPE, in
ppeWalkScene.cxx the function:

void ppeBuilder::countGeometry( ssgEntity *e )

[Plib-users] Triangles and Vertices

[Michael W. <michael.wessels@z.zgs.de>]

Hi all,
I have loaded an object *.ac in my programm with

 char Data_Path[128];
 int Num_Triangles;
  aircraft = new ssgTransform ;
  sprintf(Data_Path,"..\\Data\\");
  ssgModelPath   (Data_Path) ;
  ssgTexturePath (Data_Path) ;
  ssgEntity *aircraft_obj = ssgLoadAC ("body.ac") ;
  aircraft -> addKid ( aircraft_obj  ) ;
  ssgFlatten         ( aircraft_obj  ) ;
  ssgStripify        ( aircraft ) ;

For further manipulation I needs information about the triangles and
vertices of the aircraft_obj. I will implement shadowing after the NEHE
Tutorial Lesson 28.

What commands from plib I have to use ?

With regards

Michael
