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.

Ouch, another new 3D format! This will never end. I bet no valuable Open Source modeler (i.e. blender) support this one. The fact that asy supports PRC is good but I have no illusion about the conclusion of the 3d formats' war (just an endless pain for developpers)...
