Re: [brlcad-devel] google summer of code : Geometry Conversion Library

studied the 3dm-g file converter, you may say it is easy (if you know what was going on), But there is a steep learning curve to know what is going on. So basically an input .3dm file is passed to the opennurbs library and get a pointer to ONX_Model, now what is needed is to explore the ONX_Model

all examples compiled successful :) will find some .3dm files to test this weekend. On Thu, Mar 10, 2016 at 5:13 PM, Margaret Hu wrote: > >>For what it’s worth, ensuring robust and faithful 3DM import and export > support in LIBGCV would be immensely valuable, and

Re: [brlcad-devel] google summer of code : Geometry Conversion Library

Hi Margaret, Think of this library as a hub which converts one CAD file format to another with the BRL-CAD database format in the middle. Looking at src/conv you will see that many of the conversion algorithms are already available. E.g. to to go from *.stl to *.obj you would first use stl-g
