I haven't used cygwin myself, so I can't vouch for the usefulness of
this but you can find Anders Norlander's LGPL win32 headers and import 
libraries--which do include mmsystem.h--at:

ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/cygwin/gcc-2.95.2/

I found this from Mumit Khan's Gnu win32 page:

http://www.xraylith.wisc.edu/~khan/software/gnu-win32/

It's a bit dated, but here's some discussion from the cygwin mailing
list about it.

http://sourceware.cygnus.com/ml/cygwin/1998-12/msg00674.html

Caveat emptor. :)

<sigh>

This has happened before - the problem is that mmsystem.h described
critical OS structures and stuff for Windoze - but Microsoft - being
such *NICE* people only ship it with their own compilers.

I thought that the Cygwin guys had fixed their release to contain
a clone of mmsystem.h - but that's evidently not true or else you
wouldn't have a problem.

I have *heard* that one fix is to steal a copy of that file from
the 'WINE' project.  WINE is a suite of freeware libraries that
allow Windoze programs to run under Linux (and other) OS's.  As
such, I've heard that it comes with a copy of mmsystem.h

However, I'm sure there are other people who will tell you other
solutions.  I bet that quite a few people illegally copied mmsystem.h
from other people who own MSVC.  If so, I DON'T WANT TO KNOW ABOUT IT!

I didn't reply because I didn't have anything very intelligent to say.

puInput was tested back when I first wrote it - I havn't used it
in any 'real' program since then - so I don't have any example
programs to share.

As far as I know, it works OK - if you have a specific example
that doesn't, share it here on the list and we'll see what we
can see.

BTW: There are many more people on the PLIB developer's list - you
might get better luck posting there.

(I think that people who develop *using* PLIB are confusing themselves
with people who are developers *of* PLIB!)

Well, NT can't read digital joysticks - but some digital sticks can
also drive the old analog interface.  That might *nearly* explain
your problem.

R: [Plib-users] Hoping I'm an idiot this time too...

[Paolo L. <p.l...@ci...>]

Did you ever installed the joystick on your NT? I ask you this since for the
installation you have to tell the system to pick a file on the NT4 CD,
precisely /drvlib/multimed/joystick/x86/oemsetup.inf (there are also
joystick.dll and joystick.sys in the same directory).
If you need those files please let me know (p.l...@ci...)

I didn't experience any problem with joystick on my NT box, so no problem on
js side.

Hi, I have been trying to use the js joystick library under
Windows NT 4.0.  I cannot get any joysticks to be recognized
with my SBLive Value into which I have plugged either an MS
Sidewinder 3D or Precision Pro joystick.  These joysticks are
however recognized under Windows 98 (I'm on a dual boot system).
Does anyone know the secret to NT 4.0 joystick detection?

[Plib-users] OK so I'm an idiot

[Scott L. <va...@be...>]

found my problem (I really hate how this always seems to happen
>AFTER< I send email about it), but to make a long story short, I
was using an integer variable to rotate my viewpoint and dividing
it by 8 or so.  This meant that the program would blithely do an
integer divide and then cast the result into floating point in
the midst of an sgSetCoord call.  Ay Carumba...

[Plib-users] Hello and Performance Issues

[Scott L. <va...@be...>]

Hey guys, here's a first not to introduce myself and my project
and to ask my first performance question.  My name is Scott Le Grand
and I recently decided to use PLIB to help make a multiplatform
edition of BattleSphere (http://www.battlesphere.com) that wacky
Atari jaguar game that made a brief appearance on SlashDot as the
game with a first copy that ultimately went for $1575 on EBay.  Anyway,
while that was fun, the completion of the Jaguar edition frees up
development on current hardware which commenced about a week ago.

So my first task was to get a SkyBox up and running.  Job done, but...
With a cubic skybox composed of 6 faces of 512x512 textures, a large
window say 1000x1000 renders at about 3 fps on a LeadTek Winfast GeForce
SDR.  This seems pretty odd. Some terrain code I wrote several months
back walks all over this.  What am I missing?  Am I falling mysteriously
into a software path?  VTune shows 65% of the CPU time is spent in NVOGLNT,
about 15% in HAL, and another 15% spent in various parts of the kernel.
Any ideas?

:-O I just discovered that the changes I made some month ago, where the
3DS loader switched from ssgVTable to ssgVtxTable must have got lost
somewhere! If I understood Steve correct, ssgVTable should be phased out
of all plib code, so we should switch to ssgVtxTable ASAP, and then work
from that. I can make the changes tonight, if you don't feel like doing
it, Paolo.

[Plib-users] Cutout usage

[Paolo L. <p.l...@ci...>]

I'm trying to use ssgCutout nodes in a modified version of the 3DS loader
for supporting 3DS "billboard" objects - not to mention that can't get the
expected result! (e.g. objects staying always parallel to the screen ...).

What I did is in the following code:

...
  ssgVTable *v = new ssgVTable( GL_TRIANGLES, vertex_count, vertices,
				normal_count, normals,
				texcrd_count, texcrds,
				0, NULL);
  if ( object_name != (char *)NULL ) {
    v -> setName( object_name );
    object_name = (char *)NULL;			// global from parse_objblock()
  }
  v -> setState( state );
  if ( strstr( v->getName(), "bboard" ) > 0 ) {	// N E W  C O D E
    ssgCutout *bboard = new ssgCutout(FALSE);
    bboard->addKid( v );
    current_transform -> addKid( bboard );
  }
  else							// E N D  N E W  C O D E
    current_transform -> addKid( v );
...

Just for try, in 3DS I gave "billboard" object name to *bboard* for
detecting beyond the 3DS storing format (and they are actually detected).
The graph organization I implemented is the following (slightly different
from the original one coded in the 3DS loader from Per):

original:
			root
			  |
	    +---------+-------+
	    |                 |
	transform ...	transform
	    |                 |
	 vtable ...		vtable

w cutout (when present):
			root
			  |
	    +---------+-------+
	    |                 |
	transform ...	transform
	    |                 |
	 vtable ...		cutout
				    |
				vtable

The result is simply those objects are no longer (visible) in the scene,
both with ssgCutout(TRUE) and ssgCutout(FALSE). Can anybody tell me why? (my
billboard objects have origin at their center).

Thanks in advance -

How could it - it rotates up and down on a very small angle when I
tell it to rotate around the x axis by a small amount each frame ... 
Gimbal lock would only afffect if it I was rotating around 2 or more
axis ... (which I will in the end but for now 1 axis doesnt even work

[Plib-users] puInput

[Steve W. <st...@sh...>]

Forgive this question if it's been answered many times, but the archives site is 
down... :(

I've created a dialog box with 3 puInput fields, and 2 buttons (OK/Cancel).  
However, I can't get the input fields to do anything; I get the I-beam and nothing 
else.  I can't find an example in the example programs.

Anyone have sample code for this?

I havn't heard of "ACb" - is this some more recent
version of the AC3D file format?

Anyway, PLIB doesn't do that - so you are out of

the ase loader i wrote for plib supports multiple objects, textures, materials & sub-materials,
