I had that once on my Mdk 9.0 after installing new Nvidia
drivers.

I did not investigate much, but after reinstalling
(with --force) the X11-devel rpm every thing was OK.

[Plib-users] generic puOneShot callback problem

[Simon <sim...@ho...>]

Hi all,

 

I'm making a scrollable list of buttons that all share the same call
back function.  The idea is that the a list of names is read in from a
file.  Some processing is done with the names and then the buttons are
created and positioned with a scrollbar within a puGroup.  The buttons
are labelled in a separate method by iterating through a vector which
contains all the names.    When the button is clicked the common
callback reads the legend from button and calls another method which
uses this as one of its arguments.  The problem is that when a button is
clicked the text that is created by the method called from the call back
is garbled and the labels on the buttons appears on the wrong buttons at
random.

 

I've tried using strings instead of character pointers, declaring the
button in the create buttons method, the list goes on.  

I noticed that if I don't assign a callback to any of the buttons then I
can click them and scroll the list and the button labels are fine.  I
re-enabled the button callback and commented out the code inside so it
was an empty method.  This time the text still gets jumbled on the
button list.

 

This is a sample of the code for the create button method:

 

static puGroup          *recordBtnGRP;

static puOneShot        *recordButton;

static puScrollBar         *recordBtnSlider;

 

createButtons()

{

            For( the number of names)

                                    {

                                    //This deals with adding the buttons
to the group thats been made for them.

                                    recordButton = new puOneShot( 0 , 0,
recordBtnWidth, 20) ;

                                    recordButton->setPosition(RGmainX,
22*(currentCount));

                                    recordButton->setCallback(
recordBtn_CB ) ;

                                    recordBtnGRP->add(recordButton);

                                    }

//if the scrollbar is enabled

if(activeScrollBar)

                        {

                        recordBtnSlider = new puScrollBar(
recordBtnWidth, -5, window_height - (40 + RGmainY), 0, true, 10);

                        recordBtnSlider->setMinValue(0.0);

                        recordBtnSlider->setMaxValue(currentCount -
recordBtnGRP->getNumChildren());

                        recordBtnSlider->setStepSize(1.0);

                        recordBtnSlider->setValue(currentRecordBTN);

 
recordBtnSlider->setCallback(recordBtnSlider_CB);

                        recordBtnGRP->add(recordBtnSlider);

                        }   

}

R: [Plib-users] navigation using mouse

Andreia,

please find attached the file with the excerpt of the code I use for the
mouse navigation model in my Plib-based viewer.
The three mouse buttons are mapped to camera motion in the following way:

- Left: walk navigation on the x-y plane - click set the init, moving the
mouse while keeping left-button pressed give proportional delta for
direction and speed;

- Middle: look around - click set the init, moving the mouse while keeping
middle-button pressed give proportional delta for yaw and pitch angles -
they remains for further walk navigation;

- Right: move on the vertical plane perpendicular to the walk direction -
click set the init, moving the mouse while keeping right-button pressed give
proportional delta for vertical and lateral movements.

These seems to me quite natural as camera manipulations in a walk approach -
not suitable for examining an object though. Some simplification from the
original code could need to adapt the constant used as mapping factor
between pixels and world space.

The code should even compile (not tried), yet please feel free to ask
anything about it.

Greetings -

Paolo

In PrettyPolyEdit, you can do some thigns by mouse, for example rotate
the camera around the object. However, most camera movement is done
with keys.

[Plib-users] puMenuBar freezes app

[Simon <sim...@ho...>]

Hi, I'm using the puMenuBar as the main menu in my application.
Sometimes when the menu bar is clicked the whole application freezes.
This happens when the bar is linked to call backs for each menu item and
also when each is set to NULL.  I was using the menu bar from the 1.6
release but now im using the latest version from the CVS which is
version 1.20.  Does anyhow know why this is happening?

[Plib-users] misterious change of position

[Andreia R de A. S. <an...@co...>]

Hi,

I'm writing code in which there is a strange change of position of the 
objetcs, when I change the camera position. See how the position of the 
cilinder changes in relation to the cube when the 3rd number of 
cam_inicial is changed in line 55. Try changing it from 5 to 15 and see 
how the objects seem to change.

Any clues?

[Plib-users] douts about ssgCameraGetPosition

[Andreia R de A. S. <an...@co...>]

Hi, I'm trying to get the position of the camera with the function 
ssgGetCameraPosition but the values that are returned do not seem
correct.

The value of my camera is:

  static sgCoord cam_inicial = { { 1.0, 0.0, 0.0  }, { 0,0,0 } } ;

the part of my program that gets the position of the camera is:

	sgVec3 pos_camera;
	int xc; int yc; int zc;
	ssgSetCamera ( & cam_inicial) ;
	ssgGetCameraPosition(pos_camera);
	xc = pos_camera [0];
	yc = pos_camera [1];
	zc = pos_camera [2];
	cout<<"camera: "<<xc<<", "<<yc<<", "<<zc<<"."<<endl;

The values should be 1.0, 0.0, 0.0. But the returned values are -1, 0, 0.

I also tried this with the tux example, values don't seem correct either.
Attached is the modified tux example code.

May someone tell me what i'm doing wrong?

thank's

Hi

Sounds good to me. Did you check the function gets called? And that
you are in the right "environment". Sorry, I forgot the correct word,
but if you have several windows, you can have a camera in each one,
maybe you change one and use the other?

[Plib-users] RH9/glut/nvidia incompatibility

You probably installed the NVidia drivers, right?  Red Hat 9 ships a
broken GLUT that won't work with third party libGL's.

What happened is that they ship GLUT as distributed by SGI, not the
one in the Mesa distribution.  The SGI glut hasn't changed since 1998,
and therefore doesn't know how to link dynamically against extensions
using glXGetProcAddressARB().  So it tries to link against the
SGIX_video_resize extension statically instead.  Until recently,
XFree/DRI/Mesa didn't support this extension, so the support wasn't
compiled in.  But now they do, so the resulting GLUT depends on these
functions.  But guess what?  NVidia (and other third party OpenGL
implementations) don't support it.  So glut programs can't link.

The Mesa version has this fixed, so what you need to do is remove the
glut from Red Hat ("rpm -e glut glut-devel") and install the one from
Mesa.  Another option is, after installing the NVidia drivers, to
rebuilt the glut srpm.  The NVidia headers don't export that
extension.

I tried reporting this to Red Hat's bugzilla, but somehow wires got
crossed and Mike Harris kinda threw a temper tantrum and locked the
bug so the outside world can't see it.  If you want to re-report it
there, please be very gentle. :)

There's also a thread at the NVidia discussion site where I re-posted
the summary:

  http://www.nvnews.net/vbulletin/showthread.php?s=&postid=103801#post103801

We should probably add this to the website as a FAQ.  It's going to
bite lots of people.  I'm CC'ing the plib folks, because it affects
them too.

[Plib-users] how can I change the camera position?

[Andreia R de A. S. <an...@co...>]

Hi,
I'm trying to change the position of the camera but it doesn't work. I'm 
using the GLUT to build a window and in a function named keyboard. I'm 
using a switch, where I test if the key pressed is 'p'. If that is true I 
try to change the position of the camera using the function ssgSetCamera, 
but it doesn't change the position of the camera. Is that the correct 
function to change the position of the camera?

Thank's.

[Plib-users] Multi-texturing

[Erik U. <un...@et...>]

Hello,

If I'm not mistaking I believe there was a discussion
regarding multi-texturing support in plib on the plib-devel
list about half a year ago. Anyhow, was this feature ever
built in into plib? If so, how do I use it?

I want to stretch out a second texture over
a large VtxTable.

Do I need the CVS version of plib or is it enough with the tarballs
on plib.sourceforge.net for plib-1.7.0 or current.tgz?

xyz is the translation (positive Z is up, X is to the right, Y is forwards)
and hpr is the rotation.

  h == Heading (rotation about the Z axis)
  p == Pitch   (rotation about the X axis)
  r == Roll    (rotation about the Y axis).

Some people use the word 'Yaw' instead of 'Heading' - but Yaw begins
with a 'Y' and it gets confused with the Y axis.

The array indices go in the same order as the letters, so hpr[0]
is heading, hpr[1] is pitch and hpr[2] is roll.

[Plib-users] ssgParser, losing tokens? please help me!

[Simon <sim...@ho...>]

 Hi all, I've been trying to use the ssgParser to parse through a text
file and read it into a tree.  The problem that I have is that im
reading 3 part lines in one at a time and in the third section the
second word is ALWAYS dropped.  This may be easier with an example:

 

0 HEAD

1 CHAR ASCII

1 ADDR Submitters address

2 CONT address was continued here and here

 

(gedcom format)

 

ok well in this example the first two lines will read in fine but the
word "address" on line 3 will be skipped and the word "was" on the last
line will be missed.  I reached this point on the first day of writing
my code and spent around a week trying to fix it.  I figured in the end
that it couldn't be my code and that it must be ssgParser so downloaded
the latest CVS ssgParser and still have no success.  The exact same
problem which now makes me think that it must just be my code.  Can
someone take a look at the following and tell me where im going wrong.
Its now been two weeks stuck on the same problem and I think that I am
too far into the code to see something really obviously wrong.

 

static int parse()

         //Create the tree using the header as the root node. This works
since there

              //can only be one header in a gedcom transmission.

              tree<gedcom_line> tr;

              tree<gedcom_line>::iterator root, trHeader;

              root=tr.begin();

Do you mean actual, 3D polygonal letters with 'depth'?  Or do you perhaps
mean flat 2D text painted onto a polygon that's placed in 3D?

If it's the former, you need a 3D modeller to generate the '3D font' as
a set of models that you'd load in the usual way...AC3D can do this for
example.

If it's the latter then the FNT library can do that for you.

No, there isn't.  The glu functions render the objects directly every
time you call them - they don't build up a permenant data structure in
memory.

Nope - didn't write one of those.

I suggest you look at ssgAux - there is code there (class ssgaCylinder)
to build a cylinder - it should be pretty simple to see how to change
it to make a cone.

Hi,

I was wondering if anyone can show me how to put 3D text on the screen.
Thanks.

 

 

[Plib-users] how to transform objects

[Andreia R de A. S. <an...@co...>]

Hi,
i'd like to know if there is a way to transform a cone made by a glu 
function (gluCylinder) in a ssgEntity. My problem is that I need to put a 
cone on my scene and I didn't a method that build a ssgEntity with the 
shape of a cone. 

Thank's in advance

I know this is not ideal ... but as a temporary fix ... you could hide
the dialog, in the callback, instead of deleting it.

Yes, I agree.  That's what I'm worried about in my app ... it works ... but
in the back of my mind I know a bug lurks.  I hate that !  :)

Yes, I suggest take your problem to the devel list.  Someone there (ie. the
pui author) should be more helpful.

Damn, I hate it when the example works ... but then crashes in your own
framework.  Happens to me all the time. :)

What you need is a simple example that demonstrates the problem.

I am certain its a bug in PUI or a real bad design decision.
I wasnt able to delete the dialogbox in the callback, whatever I tried.
But then, where else should I delete it if not in the callback?

The redraw doesnt help for me.... my problem is that its only a
noticebox,
so there is no time being used in between, but anyway having the app
rely on
a fulfilled race condition is really bad anyway.

> Sorry I can't be more helpful than that.  Let us know what you find.

Still didnt get it to work... I think someone who REALLY knows (like the
developer who
wrote it :P) needs to tell us what its doing and why... they should
know...
Searching through the code didnt help me at all, whatever its doing must
be hidden somewhere.

I was trying to pop the dialogbox from the stack but it still gets the
mouse event and crashes.
I dont know what else I can do to persuade PUI that I REALLY deleted it.
:P
It doesnt say anywhere in the docs how the deletion works, but somehow
the example apps seem to
work... really weird.

I've only just started using the pui ... so I'm no expert
(although I've been using plib for years) ... but I do remember
I had a similar problem as you describe.

What I found was that the puMouse(button, state, x, y) callback
was arriving after dialog was deleted !?

I'm not sure if it was a timing issue in my code, or a bug in the
pui ... where maybe it doesn't correctly check if the dialog exists
when checking hits (if I remember correctly it seemed to happen on
the mouse up event).

In my case *maybe* it was a timing issue (but I'm not convinced yet)
... I changed my code as follows to delete the dialog after an
intensive load operation (and a redraw ... maybe the redraw is the
solution ... I'm just guessing here):

on mouse down:
- closed & deleted dialog
- loaded level (+ redraw)
- crash occurred (similar to your description)

on mouse down:
- hide dialog
- loaded level (+ redraw)
- deleted dialog
- no problems

Sorry I can't be more helpful than that.  Let us know what you find.

No, I don't think so.

[Plib-users] fntTexFont Problem.

[Allen Y. <ay...@wr...>]

Hi,

I tried to create 3D texts on the screen. I wanted to use fntTexFont to
solve my problem. However, my code kept crashing on Creating a new
fntTexFont object. The problem was that fntTexFont can't find .txf file in
my directory. However, I already created a sub_directory under my project
and the .txf file was in there. I really want to know where I should put
those .txf files and how can I make this thing work? I will be appreciated
any help. This is my code:

 

static fntTexFont **font_list ;

static const char *font_names [] =

{

            "Times-Roman.txf"

};

 

COpenGLFonts::COpenGLFonts()

{

            textout = new fntRenderer();

 

            TextOut();

 

}

 

COpenGLFonts::~COpenGLFonts()

{

 

}

 

void COpenGLFonts::TextOut()

{

            static fntRenderer *textout;

            char fname [ 256 ] ;

 

            font_list = new fntTexFont* [ sizeof(font_names) /
sizeof(font_names[0]) ] ;

 

            sprintf ( fname, "fnt/%s", font_names [0] ) ;

 

            font_list [0] = new fntTexFont ( fname ) ;  //crash here every
time!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

            fntTexFont times("Times_Roman.txf");

 

 

            textout -> setFont      ( &times) ;

            textout -> setPointSize ( 25.0f ) ;

 

            textout->begin();

               glColor3f ( 1.0f, 1.0f, 0.0f ) ;

                        textout->start2f(50.0f,80.0f);

                        textout->puts("hello");

            textout->end();

 

}
