Many 3D authoring program like Blender, Meshmixer can output U3D or RPC that you can use to embed into 3D PDF files. There are just many tools that can read the format. But beware that only Adobe Reader can show the 3D object

Thank you! Yes, I wasn't thinking about the read-time support.

Note that PDF 3D models have a static image (a bitmap) which readers that don't support 3D (most of them) will show instead. Actually Adobe Reader shows the static image too, until you click on it to activate the 3D rendered version.
