Hi Ken,
I am running into an issue with your suggestion.
I update the "DiffuseColor" property to my desired value using the method that
you pointed out. I then apply the UpdateVTKObjects() method, yet I don't see
that the glyph color changes. When I look into the state XML files, I can see
that the value was changed. What else would I need to call an update on? My
code is similar to:
...
pqDataRepresentation *rep =
source->getRepresentation(pqActiveObjects::instance().activeView());
pqPipelineRepresentation *pipelineRepresentation =
qobject_cast<pqPipelineRepresentation *>(rep);
pipelineRepresentation->getProxy()->UpdatePropertyInformation();
vtkSMDoubleVectorProperty *prop = vtkSMDoubleVectorProperty::SafeDownCast(
pipelineRepresentation->getProxy()->GetProperty( "DiffuseColor"));
prop->SetElement(0, 1.0);
prop->SetElement(1, 1.0);
prop->SetElement(2, 0.0);
pipelineRepresentation->getProxy()->UpdateVTKObjects();
pqActiveObjects::instance().activeView()->forceRender();
...
I can see that the color that I have set is set as active color in the
ColorWindow of the properties panel, but the image doesn't render the color.
By the way, I am developing against ParaView 3.98.1.
Many thanks and best regards,
Anton

Subject: Re: [Paraview] Setting glyph color to be independent of color scale
and color map
The coloring of an object (in this case, the result of the glyph filter)
is controlled by the representation object. The representation object can
be set to be either a solid color or mapping a variable. It sounds like
your glyph representation is already set to a solid color since the
default solid color is white.
There are several parameters on the representation object that control the
solid color. The most relevant is the DiffuseColor parameter. Change that
to be yellow (i.e. [1,1,0]) and that should do what you want.
