Hello,

I would like to annotate isosurface or slice values in the render view of the animation. I just rendered two very first attempts of animation of the seismic model (YT links below) and it lacks of the value of P velocity isosurface or the depth of horizontal slice. I see that time can be easily annotated in Paraview. How about other variables?

Regards,

PythonAnnotation should do the trick if the data you want to annotate with is within your dataset.
