I learned about it on RH 4.something, rpm distros have been doing it for
quite sometime.  One thing that may hide it is choosing the development
option in the initial install so that the installer automatically
installs the -devel rpms and the user may well be none the wiser.

Debian has done this for quite some time.

The regular part comes with just the .so's, the ; the -dev portion includes
the headers and the .a's in case any developers would want to
statically link.

Without touching on what *should* be done, I believe the intention is
exactly what you allude to ... install the minimum possible portion of
the library to allow binaries to run.  Remember packaging for most
people is all about pre-compiled binaries.

There are some benefits to this approach.  It minimizes download times
and hard drive consumption (don't forget that the -dev versions of the
lib package also include the .a's.)  It gives *most* people exactly
what they want.

It's been this way on Debian ever since I can remember so I'm used to
it and don't think twice about apt-get'ing the -dev portion.

But, to be fair, there is a downside to this approach (which touches
on some of the down sides to package management in general.)

I'll make you a deal: As soon as you come up with a scheme that does
exactly what *everyone* wants 100% of the time, I'll invest my life
savings in your company, or vote for you, or do what ever is

I suspect an annoying (but growing) trend with distro makers that they have TWO versions of every RPM
that relates to libraries - one is the "Development Version" - which comes with headers and binaries,
the other contains *just* the binaries.

I've seen this with the latest version of SuSE and it's *INCREDIBLY* annoying.

The header files take up very little space - and if they install the library without the headers
then it can only be used by binary-only applications.  When you try to install a source-code based
project, it *looks* like the library is installed when you ask RPM about it - but in fact it's
only halfway installed.

We never used to get this kind of complaint - but now I see them all the time.

So, look for a RedHat RPM with "Development" or "Developer" somewhere in it's title - and you'll
have what you need.

Failing that, you can download GLUT and you can either install it yourself - or (if you prefer not
to screw up the existing RPM install) just copy the header files into /usr/include/GL/

GLUT is to be found on www.opengl.org and on www.mesa3d.org - as a part of the Mesa install.

You need 'glut.h'...that's all I think.

You also need to install the -devel rpm.  I don't use RedHat but on my
Mandrake 9.0 machine I have libMesaglut3-4.0.3-6mdk as well as
libMesaglut3-devel-4.0.3-6mdk.

[Plib-users] Ssgtimedselector not working?

I did the same but loaded it into a timedselector.... But it doesnt
work.

I did everything mentioned on the website, like setting duration, adding
kids, and starting the animation.
Basicly it sits on the first frame and doesnt move.

I added the model frames from 3ds and added them as kids to the
timedselector node.

What am I doing wrong? Or is it broke somehow? Do I need to make an
additional call to update the animations?

Does anyone have a code example showing how to actually use a
timedselector node? There seems to be something magic about it .. :)

Actually, thats exactly what I was going to do... I thought maybe there
is a better way to do it, especially cause those .ase files may become
quite large.. Also, are you afterwards saving it as an ssg file? Or do
you just keep it as .ase?

Why not convert .3ds to .ase with 3D Studio Max and use the .ase's?  Thats 
the way we do it.

As to your animation questions, we are building seperate .ase files for 
each frame and loading them into a ssgSelector.  It is certainly not the

[Plib-users] Animation formats....

[SkyFlash <sky...@ch...>]

I still have no luck importing my models animated...

How does the modeler have to export the model to be of any use for
importing into PLIB?

Only formats that can load animations seem to be .ase and .ssg. The
second is unavailable so the only one working seems to be the .ase
format. But how do we need to save the model? With keyframes? Without?
And how do we load the animations from .ase into PLIB and convert them
to the .ssg format?

On a sidenote, does anyone have a anim importer for 3ds or a way to
convert 3ds animated models into the .ssg format??

In the case of PLIB, the Kernel and *many* other projects,
the second number in the version is odd for a development
version, even for stable.

So, 1.4.2 was not exactly "better" than 1.5.0 - it was
more adequately tested - and more stable - but had less
features than the development/unstable version.

We make it quite clear that 1.5.0 is unstable - and that
you should only use it if you are a developer.  1.4.x was
stable and should be used by preference.

[Plib-users] PLIB versions numbering

[torcs <to...@fr...>]

Hi All,

I'm using PLIB for TORCS as it is *really* a great
library by the features and by the "P" for portability.

I had some problems in the past from PLIB version numbering.
For all the projects except the kernel, bigger version
number means "better" or at least newer version.

I was facing a lot of support requests due to the use
of the 1.5.0 version (which was the same as 1.4.0 IIRC)
instead of the 1.4.2 which had more features.

As the releases are not frequent for the stable branch
and even less frequent for the unstable branch, it would
be a good thing to go back to only one stable branch with
increasing version numbers.

I know in advance that the 1.6.x vs 1.7.x versions will
generate confusion in the users mind as some distro
(like Debian) propose the 2 versions of PLIB.

Thanks to all for your efforts in providing such a useful
code to the others.

Bye,
Eric.

For FlightGear, we built animations as a separate layer on top of plib
rather than trying to do anything inside plib.  You specify animations
using XML wrapper files, referencing objects inside a model by name
(that wrapper files can also import submodels into the model);
FlightGear adds a callback and userdata to the scene graph so that the
animation will update automatically when the named branch is
traversed.  Here's an example from the XML wrapper for a Cessna 172P,
to rotate the rudder:

 <animation>
  <type>rotate</type>
  <object-name>Rudder</object-name>
  <property>/surface-positions/rudder-pos-norm</property>
  <factor>17.5</factor>
  <center>
   <x-m>4.84</x-m>
   <y-m>0.0</y-m>
   <z-m>-.16</z-m>
  </center>
  <axis>
   <x>0.25</x>
   <y>0.0</y>
   <z>1.0</z>
  </axis>
 </animation>

"/surface-positions/rudder-pos-norm" refers to an internal property in
FlightGear -- FlightGear publishes all of its state through a property
tree that can be loaded from or saved to XML, or accessed through a
GUI or over the network via HTTP or FTP.

I didnt find out yet. Its doing something wrong, but I didnt find it

Ok so I will try that.. what exactly is the problem with 3ds animation
loading? Is it hard? Or just not feasible?

>That's not a good sign.  Can you post one of the models that crashed it

Yes, its an orc model. It loads into my testapp fine, but on exposer
loading it crashes. But maybe I just dont get exposer.. hehe. Anyway,
here is the link:

http://www.arianne.info/files/orc.zip

What happens is that exposer just quits. No error message, just the app
stops silently.

>The term "animation" is a little vague.
>Are you talking about Skin & Bones deformation, model-switched
animation,

I just mean, can I have a model with a walk and a attack animation in
one file, and then decide which one to show? If yes, with which format
would that be possible? Or do I need different model files with
different animations, like orcwalk.ase orcattack.ase? I understand
model-switch animation is like having 2D pictures shown fast after one
another, like an animation movie? The skin and bones animation from
exposer looks a little bit unreal, and moving joint animation, I dont
even know how that works. :) Did I say yet, I am not a 3D programmer...
lol.... But I am ready for a small lection in different animations.

Ok, basicly I need to know, what looks the best, and what can be used to
create good looking game characters, and how do I get my 3D artists to
create models that are animated and can be loaded into PLIB?
For example, can they create an animation inside 3d studio and then
export it via ASE and load it into PLIB? Or are there other limitations
they need to know? Other than that huge ass table I found on the
website...And what do I need to do in PLIB to play the animation?

Ok, that was a stupid question... :P
I got it the second time I read the website docs... lol. I got carried

The only place where PLIB cares what system opened the OpenGL window
is in PUI where we ask for the size of the window using GLUT calls.

Even that can be turned off with a compile time option.

No - don't try to mix GLUT and SDL - that certianly won't work.

Just make sure you have the SDL window open and able to accept
OpenGL calls when you call ssgInit() - and then it should work
just fine.

That's quite suprising - once the OpenGL rendering context is created,
it shouldn't matter who/what created it.

Probably SDL is opening the window in a different graphics mode
(eg 24 bits per pixel instead of 16 - or vice-versa) and your graphics
card runs less efficiently in that mode.

Another possibility is that SDL created an "indirect" rendering
context instead of a "direct" one.

The problem is that not many file formats have really good support for
animations that PLIB can latch onto.

I generally use AC3D (because it's cheap and runs under Linux) - so AC3D
is pretty well supported.

That's not a good sign.  Can you post one of the models that crashed it
to a website somewhere so someone here could download it and try to find
out what went wrong?

The term "animation" is a little vague.

Are you talking about Skin & Bones deformation, model-switched animation,
moving joint animation?  All are possible under SSG.

PSL is new with the latest development version of PLIB.  I don't think
it is in any of the releases yet.  You'll need to grab the development

psl.h should be in /usr/include/plib/psl.h

[Plib-users] ref counting problem

I'm currently having some trouble with ref() counters in my PLIB game.

My game contains a bunch of manager classes:
- MaterialManager: creates/destroys materials (ie. ssgSimpleState)
- ModelManager: creates/destroys models (ie. ssgEntity)
- EntityManager: creates/destroys game entities (ie. ssgBranch)

Each manager class calls ref() for each PLIB object it creates and ssgDeRefDelete() when it destroys the object.

These classes are created & destroyed on loading and exiting levels in the game.

The problem comes in my MaterialManager class that has a list of ssgSimpleState.  The MaterialManager sets a ssgSetAppStateCallback() and thus supplies ssgSimpleState on loading AC3D Models.

My problem is that I get an exception after loading and exiting different levels a few times ... it seems to be in ssgLoaderOptions::createLeaf() ... their seems to be shared_states with 'invalid' pointers (actually to be truthful I might be deleting the states when their ref() counters are not zero :-(  ... before you say "well that's your problem" ... there is a reason for this ... I don't actually want the ssgSimpleState objects to hang around ... I know what I'm doing is wrong ... but I'm not quite sure what ssgLoaderOptions is doing ... why is it keeping the shared_states ?  can I clear it ?  or is my game logic all wrong ?).

What should I do ?  Should I really create/destroy my materials each level ... or should I load them ONCE only for the whole game ?  Each level uses quite different materials ... so I would like to destroy them ... but I'm not quite sure what ssgLoaderOptions is doing hanging onto the states ?

Any ideas ?

[Plib-users] Thx for help.. this time I need some info....

I finally figured out how to use SDL with PLIB and i got to say it works
great. Its a little bit slower though as GLUT.
Anyway...
 
My next step is to add animations to my Objects.
 
What is the prefered method to display animated 3d models in PLIB?
I read somewhere the 3ds format is not supported for animations, so
which format do I need to have my modelers create models in?
 
I would also be interested in discussions about speed or usefulness of
the formats that are possible....
I tried exposer, but couldnt really get it to work. It crashed on most
formats I tried to load, like .3ds for example.
Also I dont think its a good idea to make my 3D artists use it, as they
are probably way better using 3d studio or whatever else they are using.
 
On the same topic, how do I switch between different animations?
 
And, can I load all 3d models into my app and later attach a single
object to more than one node?
 
Thx for any help....

Re: [Plib-users] PLIB with SDL?

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

My app uses SDL_Net for network communications, it works fine.  I haven't
done anything with using SDL for graphics, however.  I converted my entire
graphics code to plib/pui.

I just add -lSDL_net to my linker line and I can use the SDL_Net functions 
just fine.

[Plib-users] Hm... are my Questions coming through? SDL and PLIB problem.

[SkyFlash <sky...@ch...>]

I am just wondering whether my questions arrived in the list... I didnt
get any replys yet, and whats worse, I didnt even receive my own
emails....
Anyway, in case this here reaches the list....

I am having a REAL bad time integrating PLIB with SDL. I tried a few
things, but by removing GLUT I usually seem to remove the capability to
display anything. :P Now, how can I make the ssg calls draw to the SDL
window I created?

And what happens if my SDL code does produce a window but not using
OpenGL? Will the ssg code recognize that? Crash?

Really, there is no way I can remove SDL and move to GLUT, so I have no
choice.... sigh.
PLEASE any help is appreciated. :)
