quadratic surfaces, "Quadrics" plug-in?

is there something like that out in the internet-jungle ;)? I Need that kind for a special tpe of animation. (i it does not exist… would be a nice feature for blender 3.8 :slight_smile: don´t you think?

(if there is no plug-in, could someone “redirect” me to the right place where i could ask the question?) (quadratic surfces would also be wonderful for doing boolean-type operations).
