Using RFO with Skeinforge

Hi All,

Can someone please explain the format of the legend.xml file within the RFO files please?
Specifically what the values in the Transform3D fields correspond to .

I would like to use the RFO files which come with the mendel models but I would also like to use Skeinforge .

At the moment I am thinking that my best approach would be to write a script to convert the legend.xml into an openscad file which I can then export as a single STL and run this through Skeinforge.

Obviously I would be really happy if there is already a flow for this since it's always nice to have someone else do the work for you but I can't find anything in the forums or anywhere else.

thanks
RB

See MultipleMaterialsFiles, example legend.xml and RFO.java.

Bob,

Thanks for the info, I had already found these files though and unfortunately what they don't do is explain the Transform matrix and what effect the various rows and columns have on a model .

Interestingly the RFO files only seem to work in reprap host software and not in Repsnapper although the latter also has an option for reading RFO files.

Do you know where there is any documentation on the Transform matrix ?

thanks
RB

It is a "4x4 homogeneous transform", see Wikipedia for more info.

What advantage is there in using the RFO as compared to the .stl files?

RFO is nothing more than a collection of .stl files with a transform matrix associated with each one compressed into a zip file (renamed as .rfo), ergo the titile of the wiki page MultipleMaterialsFiles.
This is supported by the RepRap Host (and RepSnapper AFAIK) and allows creating a print plate out of seperate STL files.
Skeinforge does not currently support RFO files so, if you want to do the same thing using Skeinforge you must first use some software to load and position all of the desired objects (STL files) and then export as a single STL file that can then be processed by Skeinforge.
