I am designing a particle physics visualization where electron accelerates in a hole and multiplies in many other electrons in a high electric field through avalanche. I know that Blender has adequate tools for this visualization such as blurring and some other features.
I however would like to do such an visualization with Gnuplot where I can use AWK inside and add a background picture like this here.
However, I am unsure about other features which I will miss if I use Gnuplot.
How can you substitute Blender with Gnuplot?
