Hello everyone .
I am the developer of Buf3d/Buf3d+ and understand your comments and share them , but internal multiresolution technology of Buf3D has taken me years of development, and I hate advertising applications. LDD loader has been an insane effort ( 3419 parts revised one through one ! ) and is free to Buf3D .
Concerning the issue of export to 3D , its operation is not perfect, libraries as LGEO generate more realistic models for the treatment of materials is better than Buf3D, but so far have not found any LDD reader that supports as many parts as this, except those using the geometry of Lego (which is protected by Lego) . But I'm a developer , I'm not the best person to rate it! ;)
It is a choice , (that was just my interest with the post) and i wanted to share it
(Ops! the geometry is from Ldraw library, is loaded online when you show a ldd/ldraw model)
