How to save high-quality 3D graphs by using glview.grabFrameBuffer().save()

[Xiaoxue Zhang]

Dear All,

I have one problem when saving 3D graphics by using glview.grabFrameBuffer().save(). The resulted figure has low quality.

Could anyone tell me how to save high-quality 3D graphics?  Look forward to your help.

The official documents is shown via this link http://www.pyqtgraph.org/documentation/exporting.html.

The detail is 

"

The exporting functionality described above is not yet available for 3D graphics. However, it is possible to generate an image from a GLViewWidget by using QGLWidget.grabFrameBuffer or QGLWidget.renderPixmap:

glview.grabFrameBuffer().save('fileName.png')

See the Qt documentation for more information.
