Summary0010708: vtkMapper::InterpolateScalarsBeforeMappingOn interfers with 2D actor
DescriptionIn the following example there is a cube with scalars on the PointData, and a lut is applied to its mapper.
There is also a line with a 2D actor in the scene.
If InterpolateScalarsBeforeMappingOn is not called on the cube's mapper, the line is correctly red, but if it is called, then it looks like the cube lut is interferring with the rendering of the line.
And if there is more 2D actors, the first one that is added to the renderer always presents the same problem.
Additional Informationpicture good.png shows the line correctly rendered in red when InterpolateScalarsBeforeMapping is Off on the cube's mapper.
picture bad.png shows the wrong rendering of the line when InterpolateScalarsBeforeMapping is On.
TagsNo tags attached.

 Does the problem still occur with VTK 5.10 ? VTK 6 ?

 The problem is still there with VTK 5.10 and VTK 6.0
I updated the example code to be used with 6.0

    BUG 10708: Fix vtkPolyDataMapper2D color mapping
    
    If another actor in the scene enabled GL_TEXTURE_2D and the
    vtkPolyDataMapper2D's input had a texture coordinate attribute, the
    vtkPolyDataMapper2D would apply the texture map while mapping the
    input. Fix by disabling GL_TEXTURE_2D if ScalarVisbility is off.
