Rudimentary DSF parser in C#

CypherFOX

Greetings,

Just sharing the core classes because I'm super-happy to have gotten it as far as I have.

I actually got a native DSF object file to directly import to a mesh in Unity, based on this importer code.

Cool. DSF is DAZ Studio Foundation class?

Greetings,

DSF is DSON Support File and contains the basic information about the object.  It's roughly the same as an OBJ file, but the idea is that DUF files aggregate references to DSF and image files, so those things can remain in a known location, while the DUF files move around.  Or, put more technically: Asset definitions within a DSON Support File (DSF) are pure definitions and represent information that can be shared among instances.

What I wanted was the ability to load a scene file (DUF) directly into Unity, without having to export/import.  What I found was that DUF files reference other DUF files, which ultimately do NOT include the individual vertices, instead they reference .DSF files which do contain the vertices and polygon groups.

So the first step in doing the whole thing was to get the DSF files to load in as meshes in Unity, the first pass of which is what I got working last night.

Good job the link you gave has a problem when I try and follow it but I think the content is the same as this link?

Pretty much; I had automatically changed the link to `https` because...everything is https these days, and that _doesn't_ work for the docs links. :). I fixed it, but yes...that's the doc starting spot.

Nice work on this. I've also been playing around with Daz files. I got the DSF object by using "paste special" in Visual Studio. I took Genesis <version>.Dsf and selected all then copied into the source code.

This gave me a rotoobject which I renamed and modified to suit the task.  I also did morph files, a sample I posted here (your code didn't inlcude the modifier_library).

I hope this helps! :)
