AcrobatReader can display 3D objects embedded into PDF documents. Until now the only way to create this kind of impressive documents was by mean of the official acrobat 3D suite. Now MeshLab an open source tool for mesh processing has added support for saving meshes in U3D format.
So now you simply need to convert your mesh into u3d format, include the small snip of tex code generated by MeshLab into your latex document and then compile it with pdflatex.
