sintegrial / qwtplot3d Goto Github PK

I'm getting these white lines thru the center of my plots. It seems to happen on large mesh files. By larger, I mean greater than 2000x2000. It also happens on smaller meshes when the resolution is lowered, as in the 3rd and 4th images which is a 1200x1200 mesh.

EDIT: apparently the white lines appear on any mesh whenever a lower than full-resolution is selected.

I want to change the size of the volumeplot total, but do not know what to change
These points are too small

Hello,
Working on this began 2 day ago but failed to implement one.
I have duplicated a demo and re-configure it as a single project. For example, the simpleplot or dynamic plot can work well as a single project but shows memory violation error while I tried to display it inside a frame. Here is what I did
The object is declared as a member of TestGUI inheritted from QMainWindow
#include
#include "difplot.h" // given simply qwt3d plot things

namespace Ui {
class TestGui;
}

class TestGui : public QMainWindow
{
Q_OBJECT

public:
explicit TestGui(QWidget *parent = 0);
~TestGui();

private:
Ui::TestGui *ui;

Qwt3D::GridPlot * oPlot;
};
#endif // TESTGUI_H

What I can do to show it in TestGui.cpp if the main.cpp given as
#include "testgui.h"
#include

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
TestGui w;
w.show();

return a.exec();
}

The recent addition of _isnan breaks builds on Mac OSX.

isnan is a valid replacement.

Can a conditional check for Q_OS_MAC be created somewhere that will define _isnan to be isnan.

Not 100% sure the best way to do this or I would submit a patch.

Thanks

Hi,
I cloned the git repository yesterday and tried to build with both QtCreator and VS2010, on Windows 7, with QT 4.8.2.
I get the following error:

d:\3rd_party\qwtplot3d\qwtplot3d-qt4.8.6-vs2010-x86\include\qwt3d_types.h(247): error C3861: 'isnan': identifier not found

It seems Q_OS_WIN is not defined.

When using the mesh program and after opening the Lighting dialog, you can't close the dialog by pressing OK. OK simply doesn't work and you have to close the dialog by pressing the X in the dialog's title bar.

Hi all,

we've been using this library in our projects and it has been working greatly.
Unfortunately after upgrading our application from Qt 5.9 to 5.12, the widget where the plot should be is not properly rendered anymore, it is completely blank. We think it is an issue caused by the base class the plots derive from, QGLWidget. That class has been deprecated and it is not supported anymore. New applications are encouraged to use the new class QOpenGLWidget.
As a matter of fact we modified the library to use the new class and the applications is now working as expected.

The new modified library is available here
https://github.com/calogeromauceri/qwtplot3d/tree/port_to_qopenglwidget

The library is working in our use cases, but some examples are not working anymore. More work is needed to finalize it, but we do not have enough resources to allocate to this. For that reason the new code is there for whoever wants to contribute.

We will send a "pull request" to merge our changes to the original project, hoping this can help in keeping this lib alive and useful.

Hi,
In last qwtplot3d version, I am able to compile only the debug configuration. When I switch in Release configuration I get the following error:

C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.CppBuild.targets(392,5): warning MSB8028: The intermediate directory (Win32\Release) contains files shared from another project (qwtplot3d.vcxproj). This can lead to incorrect clean and rebuild behavior.

Any suggestion or tip?

Thanks in advance
