You are correct; Acrobat is the optimal choice for managing 3D PDFs. FoxIt Reader also has this capability, albeit with some complications related to internal JavaScript.
I have extensive experience with 3D PDFs, having mastered this document format a long time ago. I wanted to push its limits to explore its full potential.
Due to certain issues, I've begun exploring alternative avenues, such as branching into WebGL. You can find more information on my WebGL endeavors at http://webgl.tarn.us.
