There seem to be a few people who’ve shown interest in this as well - there seems to be a working version by 80prozent here:
http://away3d.com/forum/viewthread/975/

but i can’t find any way of doing this other than the bitmap generator version which is great for debugging but looks ugly if its the wireframes themselves you want to show.

For a pet project of mine I created class that takes a mesh and returns a wireframe mesh built from SegmentSets.

That’s fine, but you can end up with a very busy mesh as every edge is traced which shows up all the tessalation that has been applied. Useful for debugging though.

I added in an option to do planar edge removal, so a flat n-gon which has been split into many triangles is displayed as a simple outline. Looks much cleaner.

You can see it in action here on some very simple models:

Click on the Elite logo to see other ships from the BBC game. Apologies for the huge size of the images, it runs on the iPad 3.

If anyone is interested in the class, let me know.

Very nice! Doing some research atm on a debug shader solution for Prefab, I would surely be interrested to see how you handle the problems.

Thanks, the Mesh to Wireframe class is attached. Not sure if it’s something Away3D could use in the core or if the existing wireframe texture is preferred.

Prefab3D looks like a nice project - I’ll take a look. I’m more of a coder myself but know graphic design people who would prefer something a little more visual to put together scenes.

Happy to help out if I can on any issues you might have, but I expect you guys are way ahead of me.

I cannot download the file. please send to fabrice3d at gmail dot com

Actually Prefab is made for devs and designers. Tho in practice its seems to be used by a large majority of devs.
