Unfortunately, I cannot see your row and column values. If I modify your =
source

  int columns =3D 40;
  int rows =3D 50;

I can see a similar picture (not twisted to the degree of your example).
Try to rotate it with your left mouse button and scale with your wheel.
I think, you will see something nicer than. Not actually the solution,
though.

It is in this example, because the z maxima climbs up to 2000 and the
aspect ratio of the poor thing turns from worse into ugly. You can
control it with Plot3D's scaling properties (also independent for all
three dimensions). The tic lines probably require some manual adaption
in such cases, but you have access to all of the 12 axes in order to
adjust them.
Another possibility is to pre-scale your data befor feeding them into
loadFromData.

Unfortunately I never tested it against this system. I hold a commercial
Qt license on Windows and don't bother there with g++ (probably I
should, for Qt4). BTW, the compiler option adheres to Visual C++, so you
can safely delete them.

I've used Qt4.2.2 + Visual Studio + qwtplot3d0.2.6 for this.

I have just seen that there's a compiler warning:

g++: unrecognized option `-GX'

I'm not sure, if this could be the problem?

Re: Another Simple-Plot Example

The data field is calculated by some complex algebraic algorithms, but 
just for testing issues: Setting line 17 e.g. to

newdata[i][j] = (double)(i*j);

results in this output:

http://students.informatik.uni-luebeck.de/~muellefl/unknown1.jpg

So that it seems, (at least for me) that it's not a data dependent problem.

I'm using a Windows system with Qt 4.2.1, developing in Eclipse with CDT 
(i.e. compiling with MinGW).

Another Simple-Plot Example

[<fic...@gm...>]

Hello everyone,

I tried to find another simple example for loading z-values, but I 
didn't find one. It would be great if someone would be so kind to mail a 
small example, that creates a plot just like the one in the "simple 
plot"-example, but with precomputed z-values.
I'm also not sure which subclass of Plot3D is best for this purpose.
The background of my question is, that I'm using the CImg-library (maybe 
someone knows this lib) for the image processing algorithms and I want 
to display some 2D image data as 3D plots. Here is an extract of what I 
tried so far (I used a lot of the simpleplot example here):

The header file:

#ifndef FSURFACEPLOT_H_
#define FSURFACEPLOT_H_

#include <math.h>
#include <qapplication.h>
#include <qwt3d_surfaceplot.h>
#include <qwt3d_function.h>
#include "CImg.h" 

using namespace Qwt3D;

class FSurfacePlot : public SurfacePlot
{
public:
    FSurfacePlot(cimg_library::CImg<>& data);
};
 
#endif 

And the source file:

#include "FSurfacePlot.h"

  FSurfacePlot::FSurfacePlot(cimg_library::CImg<>& data)
  {
    setTitle("Time-space image");

    int columns = data.dimx();
    int rows = data.dimy();
    double** newdata = new double* [columns];
    for( int i = 0; i < columns; ++i)
        newdata[i] = new double[rows];
          
    for(int i = 0; i < columns; i++)
    {
        for(int j = 0; j < rows; j++)
        {
            newdata[i][j] = data(i,j);
        }
    }

    loadFromData(newdata,columns,rows,1,columns,1,rows);

    setRotation(30,0,15);
    setScale(1,1,1);
    setShift(0.15,0,0);
    setZoom(0.9);

    for (unsigned i=0; i!=coordinates()->axes.size(); ++i)
    {
      coordinates()->axes[i].setMajors(7);
      coordinates()->axes[i].setMinors(4);
    }


    coordinates()->axes[X1].setLabelString("x-axis");
    coordinates()->axes[Y1].setLabelString("y-axis");
    //coordinates()->axes[Z1].setLabelString(QChar(0x38f)); // Omega - 
see http://www.unicode.org/charts/

    setCoordinateStyle(BOX);

    updateData();
    updateGL();
  }

Everything compiles without errors, but when the widget is shown, I just 
see a black window with a wireframe box, whose colors are changing in a 
weird way.
Maybe you can tell me, where I'm thinking wrong or give me some other 
clues!?

Best regards!
Florian

ANN: PyQwt3D-0.1.2

[Gerard V. <ger...@gr...>]

What is PyQwt3D?

- it is a set of Python bindings for the QwtPlot3D C++ class library
  which extends the Qt framework with widgets for 3D data visualization.
  PyQwt3D inherits the snappy feel from QwtPlot3D.
  The examples at http://pyqwt.sourceforge.net/pyqwt3d-examples.html
  show how easy it is to make a 3D plot and how to save a 3D plot to
  an image or an (E)PS/PDF file.

- it requires and extends PyQt, a set of Python bindings for Qt.

- it supports the use of PyQt, Qt, Qwt, the Numerical Python extensions
  (any combination of NumPy, numarray, and numarray) and optionally
  SciPy in a GUI Python application or in an interactive Python session.

- it runs on POSIX, Mac OS X and Windows platforms (practically any
  platform supported by Qt and Python).


New features:
- support for Python-2.5 (requires PyQt and SIP snapshots or the future
  PyQt-3.17, PyQt-4.1 and SIP-4.5)
- support for Qt-4.2.x and -4.1.x
- support for NumPy-1.0, see http://numpy.scipy.org
- PyQwt3D.OpenGL gives access to a small subset of the OpenGL API
- EnrichmentDemo.py example demonstrates PyQwt3D.OpenGL

The home page of PyQwt3D is http://pyqwt.sourceforge.net.


PyQwt3D-0.1.2 requires:

1. Python-2.5.x,-2.4.x, or -2.3.
2. PyQt-4.0.x, or -3.16.x (or the future PyQt-4.1 or PyQt-3.17)
3. SIP-4.4.x (or the future SIP-4.5)
4. Qt-4.2.x, Qt-4.1.x, Qt-3.3.x, or -3.2.x.
5. QwtPlot3D-0.2.6.

How to export a 3D plot to an animated GIF file?

[ion v. <ion...@ya...>]

    Hello, 
  
 I wonder if it would be possible to save an animated 3D plot, like the ones in the mesh2 example, to an animated GIF or to an AVI file.  Do you know how to achieve this? 

 Thanks in advance, 
 Ion

I do not think that you can use QwtPlot3D easily from wxPython, but there exists
bindings to make QwtPlot3D work with PyQt (Python bindings for Qt), see:
PyQwt3D at http://pyqwt.sourceforge.net/

[<tc...@na...>]

Dear QWT-PLOT3D desinger ;

I have a problem in QWT-PLOT3D. QWT-PLOT3d can be combined with wxPython 
User Interface ?
Now. I use the QWT-PLOT3D feature to make my need, but I will intergrate the 
result of QWT-PLOT3D into My User Interface .

Thank for your helps!
Best Regard!

Hi,

 Thanks for your response.

 So should I compile qt from scratch with opengl enabled, or do you know of
a cygwin qt package precompiled with opengl.

 Can I compile labplot without opengl (I tried ./configure --disable-gl but
the make crashed with a whole list of errors)

Thanks,
AR

Hi,

 I have been trying to compile labplot (1.6) on cygwin/winxp. I had to edit
the configure script and make the section on "klineedit" case sensitive,else
the configure script can't find the KDE/QT libraries (which I installed by
downloading the cygwin binaries as tarballs from kde-cygwin website). The
configure script ran successfully, but running make causes a problem with
qwtplot3d/qt enabled. Qwtplot3d doesn't compile on cygwin without a host of
errors (even the standalone qwt source code downloaded from their site and
compiled separately using qmake/make). Compiling labplot with opengl
disabled  doesn't work either, with a whole host of errors coming from the
header " functions.h". Compiling with opengl enabled produces the following
errors from qwtplot3d/qt:

render pixmap problem

[<bon...@gm...>]

Hello everyone:
       In one of my projects, i decide to use render pixmap as a pixmap to
draw on the background of my drawing program.What the problem is, when i us=
e
renderpixmap to get the pixmap, i found out the pixmap is not exact the
drawing. Data drawing is scaled in the center and there are blanks around
the data drawing. I just want to get the drawing without the blank. How can
I get exact data drawing size and position so i can use renderpixmap to get
the data drawing? Did i say it clearly? Any suggestion is my preciation.
thanks a lot.

qwtplot3d-0.2.6_qt4.1_MSVC2003 => OK!

[Luis G. M. <lma...@in...>]

Hi all,

I've just successfully built the latest version of qwtplot3d (0.2.6, as far
as I could find), and all the included examples with Qt4.1 using
MSVC2003(7.1 - WinXP platform, obviously).

So, I think it can be said that qwtplot3d is Qt4.1 compatible! ;-)

Cheers,

Gustavo

ANN: PyQwt3D-0.1.1

[Gerard V. <ger...@gr...>]

What is PyQwt3D?

- it is a set of Python bindings for the QwtPlot3D C++ class library
  which extends the Qt framework with widgets for 3D data visualization.
  PyQwt3D inherits the snappy feel from QwtPlot3D.
  The examples at http://pyqwt.sourceforge.net/pyqwt3d-examples.html
  show how easy it is to make a 3D plot and how to save a 3D plot to
  an image or an (E)PS/PDF file.

- it requires and extends PyQt, a set of Python bindings for Qt.

- it supports the use of PyQt, Qt, Qwt, the Numerical Python extensions
  (any combination of NumPy, numarray, and numarray) and optionally
  SciPy in a GUI Python application or in an interactive Python session.

- it runs on POSIX, MacOS/X and Windows platforms (practically any
  platform supported by Qt and Python).


Changes:
- support for NumPy, see http://numeric.scipy.org
- support for SIP-4.3.x
- build fixes for MacOS/X


The home page of PyQwt3D is http://pyqwt.sourceforge.net.


PyQwt3D-0.1.1 requires:

1. Python-2.4.x or -2.3.
2. PyQt-3.15.x or -3.14.x.
3. SIP-4.3.x or -4.2.1.
4. Qt-3.3.x, -3.2.x, or -3.1.x.
5. QwtPlot3D-0.2.6.


Have fun -- Gerard Vermeulen

The errors reported are from the X-Windows system. No blame for
them but they might likewise originate in Qt or also some other X
related system subtleties.
Unfortunately I didn't check the last official qwt3d version against 4.1
yet (4.0 only).
So, could you be more specific what the examples are, spitting the messages ?
All of them, also the simplest one (simpleplot)?
This way, I could limit the evaluation and skip some of the more
Qt-related suspicious stuff.

Anyway, I'll look into it at weekend, when I have access to my linux
test system.

qwtplot3d-1.2.6_qt4.1_linux

[Ralf W. <rwi...@za...>]

Dear liste,

I have used qwtplot3d under qt3.x without any errors. Under qt4.1 qwtplot3d
compiles without errors.  But if I want to test the examples a long list of
error messages appears:

X Error: BadDrawable (invalid Pixmap or Window parameter) 9
  Major opcode: 55 (X_CreateGC)
  Resource id:  0x4000010
X Error: BadDrawable (invalid Pixmap or Window parameter) 9
  Major opcode: 55 (X_CreateGC)
  Resource id:  0x4000010

  Major opcode: 56 (X_ChangeGC)

X Error: BadGC (invalid GC parameter) 13
  Major opcode: 56 (X_ChangeGC)
  Resource id:  0x400001f
...

The examples of qwtplot3d could be used but with these error messages. qt4.1 
was compiled and all examples in qt4.1 worked without any error messages. Can 
anyone help me? 

The operating system is: Linux version 2.6.13-15-bigsmp (geeko@buildhost) (gcc 
version 4.0.2 20050901 (prerelease) (SUSE Linux)) #1 SMP Tue Sep 13 14:56:15

Ok, I could grant axis access like for the axes in coordinate system.
In mesh2 I adapt the colors simply by means of Plot3D::showColorLegend(bool).
This function also calls updateGL(). Could you check, if the flickering
remains ? If so, a compilable piece of relevant code would be a nice
thing (tm) ..

I think it's not easily doable for now without a hack. Maybe I'll
introduce in the future 3D labels in the sense you can find in some
other libraries/applications. That means, that labels are not longer
restricted to be projections on the background but can lie in x-y, y-z
or x-z plane (e.g.). I have this feature still not scheduled yet -
meaning it has low priority for the moment. If it comes to
implementation I'll take in account more degrees of freedom for
positions in the sense you requested.

The final solution is in the pipeline. Nevertheless it should be
possible to emulate this feature for the current version by utilizing
SurfacePlot::loadFromData(Qwt3D::TripleField const& data,
Qwt3D::CellField const& poly).
If you provide the right CellField for the function you can produce
non-connected components - essentially a multiplot of surfaces. This is
not perfect (of course there are reasons for a specific implementations)
but should work.

Color Legend issues

[ion v. <ion...@ya...>]

Hello Micha,

I would like to change the fonts of the numbers
displayed by the color legend, but the API of this
class doesn't provide a method to do this. It think it
would be really usefull to provide a way to access the
axis member of the legend.

Another issue with the color legend is that it is not
automatically updated when you change the colors or
the transparency of the data, evan if one calls
updateData() or updateGL(). The only way I could
achieve this was to hide and then reshow the legend,
but this results into disturbing flickering.

I also have a question regarding the axis labels. I
would like to display the label for the Z axes
vertically and not horrizontally as it is displayed by
default. How can I do this?

And finally, is it possible to implement multiple
plots? I saw that there's a MultiPlot class available,
but I'm not sure how to use this.

With best regards,
Ion Vasilief

Install Qwtplot3d on Win/MinGW

[<mw...@gm...>]

Hi,

I downloaded qwtplot3d-0.2.5.zip, extracted it and using MinGW/MSYS I did:

cb@LAPTOP ~
$ cd qwtplot3d

cb@LAPTOP ~/qwtplot3d
$ qmake qwtplot3d.pro 

cb@LAPTOP ~/qwtplot3d
$ make
make -f Makefile.Release
make[1]: Entering directory `/home/cb/qwtplot3d'
make[1]: *** No targets.  Stop.
make[1]: Leaving directory `/home/cb/qwtplot3d'
make: *** [release] Error 2

Makefile.Release is empty besides some initial commentaries. I am using Qt
4.0.1

Can someone tell me what I did wrong?

Thank you,
Micha

Re: SIGSEGV from qwt3diodummy constructor

[Borries D. <de...@bi...>]

The new version appears to work fine with Slackware 10.1. My own application
as well as all the examples compiled and worked. I also compiled LabPlot 1.5.0.2
against the qwtplot3d snapshot and it loaded fine, although several functions inside
of LabPlot don't seem to work. I never used LabPlot before and am not sure if
these are LabPlot bugs or bugs originating elsewhere. I suspect they are caused
by LabPlot, although no debug info is printed.
