RuntimeError: OpenGL got errors (Check before draw): GL_INVALID_VALUE
is there a way to use Qt QML backend? Qt QML uses QML Item , Its also possible to get the QML to create framebuffer, I am very new to OpenGL , used Pyvista , Pyqtgraphs with Qt widgets, I am looking for options to move to QML (preferably with Qt6). Looks like pyvista with QML is complicated as the way VTK works, Vispy seems much promising with both 2d charts (line charts) and 3d charts (surface mesh).
Some more details are https://stackoverflow.com/questions/68517058/can-not-get-pyvista-render-to-work-with-qt-qml-qquickframebufferobject , I am willing to contribute but could not get where to start.
@ericgyounkin If you are using VisPy 0.7+ then you should look at adding the ShadingFilter to your MeshVisual: https://vispy.org/api/vispy.visuals.filters.mesh.html#vispy.visuals.filters.mesh.ShadingFilter
You can access the default instance of this through the
MeshVisual.shading property or you can create your own filter and attach it after you create the MeshVisual.
You can see examples of this in this example: https://vispy.org/gallery/scene/mesh_shading.html
scatter.antialias = Falseand see if that fixes what you're seeing
