OpenGL.error.GLError

[Вадим Евгеньевич]

I'm trying to apply 3D.

Here is an example of my code:

"""

from pyqtgraph.Qt import QtCore, QtGui

import pyqtgraph.opengl as gl

import sys

class Terrain(object):

    def __init__(self):

        """

        Initialize the graphics window and mesh

        """

        # setup the view window

        self.app = QtGui.QApplication(sys.argv)

        self.w = gl.GLViewWidget()

        self.w.show()

        self.w.setWindowTitle('Terrain')

        self.w.setCameraPosition(distance=30, elevation=8)

    def start(self):

        """

        get the graphics window open and setup

        """

        if (sys.flags.interactive != 1) or not hasattr(QtCore, 'PYQT_VERSION'):

            QtGui.QApplication.instance().exec_()

    

if __name__ == '__main__':

    t = Terrain()

    t.start()

"""

But in the end I get an error:

"""

OpenGL.error.GLError: GLError( err = 1282, description = b'\xed\xe5\xe4\xee\xef\xf3\xf1\xf2\xe8\xec\xe0\xff \xee\xef\xe5\xf0\xe0\xf6\xe8\xff', baseOperation = glViewport, cArguments = (0, 0, 160, 160)

)

"""

Has anyone encountered such a problem? If so, how to solve it?
