Currently a waste of time, although importing dxf drawings would be potentially good. However, for now, I would say that importing SVG is more practical. DXF is a closed standard, and a moving target. Seems more trouble then its worth. There are other ways of turning dxf into svg for k3d import. For the moment, other software like blender/wings can always be used as an inbetween for getting less common formats into k3d. Or perhaps some generic library can eventually be used for less common formats.

The question mark was because I wasn't sure if that was the extension, and if there were another :) Cheers!

Actually I've been looking at the dxf file format and as you said is probably not a very good option as it is getting left behind and doesn't even support all the new stuff going into Autocad. I think I'm going to start with the SVG, but before (as stated on the wiki) I want to design some kind of tunnel class as the file formats usually have pretty much the same components and it's difference is mostly on parsing, and doing this class I'm probably going to speed up my workflow later and don't be redundant, what do you think about it?

Lets see if I can reply correctly :-D (import Tim, Bart) You mean creating an intermediate class that injects data to the K-3D format. Then calling its methods from the Parser? Seems this class is a gprim_factory (after browsing the code). Check Mattia's code on collada_io (gprim_factory.h/cpp) You said you want to go first for SVG. Lets review the list in timeline: * .svg * .obj * .collada (.dae) * ogre Cheers!

I think I know what you mean by "tunnel" and I like the idea. Things that are important to put in the tunnel, as far as meshes are concerned: -Basic Mesh structure -UVs (stored in various UV sets. I think someone else had a discussion about how k3d stored these) -Face normal (which way is each face pointing) -Vertex Colors (also stored in vertex color sets) -Soft and Hard edges (every edge is flagged as either hard or soft) -Material info (or groups of polygons that seperate various materials) -Any explicit normals set (any vertex normals that are not automatically generated, this should be optional and turned *off* by default so that they are normally ignored.) I discussed this with some of my better students, and it was agreed that this is what they usually need when importing meshes. (in the best case. In some cases, less info is still enough.) At an object level: Node name (usually comes from the transform node) Transform Parenting (child objects and parent objects relationship) Layer membership (what layers is the object in) Material Assignment, what material is assigned to the object This list should probably get longer, but these are some of the most important things... I suppose that for SVG, it will require nurbs to import them.

Hi joaquin,
By tunnel class I meant like a wrapper for parsing, it's something a little bit different than the gprim. actually the obj_io has something similar implemented trying to separate all the parsing from the main code. As far as the list goes I think that's fine. I'm going to dedicate this evening to update the wiki on the timeline and schedule, I'll let you know when I get it :-) Bests, Carlos

Would SVG be best to do last because it depends on Nurbs, or do we already have enough Nurbs stuff that it would be do able even before those new Nurbs plugins get done?

As of what I know (correct me if I'm wrong hehe) the nurbs base code is already implemented fine, the thing with the nurbs plug-ins is to actually use them. Actually on Cartsen sample plug-in he already uses nurbs curves which for now is probably almost all we need :)

Yes hehe :) now that you put it that way I think it's going to be really helpful for the nurbs plug-in tools too, so I'm going to try to speed it up :) I haven't imported svg to anything before so right now I'm reading the documentation which is pretty long hehe. I'm going to put the link on the wiki.
