Acrobat X Pro can only place native 3D files into PDF files - U3D and PRC formats. Both can contain animations as per their specification, but it's limited - you cannot for example animate on a vertex level.
Animations will play without JS, but to control them beyond the basic 'play bar' on the 3D tool, you would need to write some advanced code.
