Hello everyone,
I'm fairly new to PyQtGraph, and for the most part I have been having
tremendous success. I am creating an application that does some analysis on
objects in 3D space, and generates plots based on their geometry. Currently
my plots are all 2D, with an image view and linked axes to show data
arising from the underlying model geometry, however I was hoping to also
include a 3D plot *showing* the geometry. Going through the PyQtGraph
examples, the GlScatterPlotItem looks to be precisely what I am looking for.
Oddly enough, the example runs perfectly fine, however when I try to
implement this into my application I got an error. My first instinct was to
bring the GlViewWidget outside of my GraphicsLayoutWidget, and plot
independently. This worked.. kind of. I can add a GridItem to the
GlViewWidget, and that renders fine - I can interact with it as I can in
the examples. However, upon trying to add a GlScatterPlotItem I get the
following error:
line 114, in addItem
self.checkOpenGLVersion('Error while adding item %s to GLViewWidget.' %
str(item))
line 535, in checkOpenGLVersion
verString = glGetString(GL_VERSION)
line 415, in __call__
return self( *args, **named )
line 230, in glCheckError
raise self._errorClass(
OpenGL.error.GLError: GLError(
err = 1282,
description = b'invalid operation',
baseOperation = glGetString,
cArguments = (GL_VERSION,)
)
What baffles me is that the examples work without issue. Some googling lead
me to upgrading mesa drivers, however that did not seem to fix the issue -
Any ideas on what I could do to make this work?
