Sorry, I fail to understand your comment.

On one hand, MeshLab can convert from other 3D formats to U3D (older Adobe 
format) and embed U3D into PDF files via LaTeX with movie15 package, thus
it may be useful in 3D PDF workflow in general, on the other hand it does 
not have anything to do with ConTeXt.

As to the module Renaud Aubin wrote to support 3D annotations - it is 
mkii thing, for example it uses "definefileinsertion" that did not find 
its way into mkiv IMHO.

While MeshLab may be of great use if you have to convert old data or 
process output from some existing tool, in cases when you make your model 
from scratch by hand or create 3D model file in your own program Asymptote 
may be a better choice since it supports newer PRC 3D format, that is much 
richer in features and has better prospects when it comes to support and 
development by Adobe. On the minus side Asymptote is under active 
development and some of its advantages are not there yet - but so is ConTeXt.


         Sincerely,, Michail
