Where's the 3D Sketchup models support!???

Hehe... just kidding people. But i'm looking forward to it. I would love to see my 3d cabinets rotating on the pictures panel while selecting a game to play. How far is this feature from the current QMC2MAME version?

The idea was (and still is) to use Qt3D / QtQuick3D... after having learned how to use QML for QMC2 Arcade, it shouldn't be too far away actually, but Qt3D is still not part of Qt 5 as it was expected, but it looks as if it could be in 5.2... see here for example: http://lemirep.wordpress.com/2013/03/24/what-happened-to-qt3d/

That's why I postponed it for now...

Oh man, hope they implement that in the next version. Fingers crossed

And do you have plansto include .jpeg support to the artwork files, instead of .png only?

Well, there are two main reasons for using PNG only: performance and the openness of the format. I may change this in the future to allow for additional formats optionally, but the more formats there are the longer it may take to find images in the file-system or ZIP. The actual loading of images is not the problem since Qt has simple/generalized APIs for this... but when the first load fails, it will have to search and load the next possible format... I don't really see a big win by this. Every image manipulation program can create / convert to PNGs nowadays, and it's what's created by MAME/MESS anyway, too . So what do you need JPEG for (or whatever format)?

EDIT: Qt supports these formats, BTW.

The PNG format is fine and support lossless data compression.
I see no benefits to use the JPEG format.

Well, I have an explanation for this:

Example: Flyers. When you download flyers from ArcadeFlyers (thousands of them) they are all in JPG format already. If you begin converting them one by one in PNG, it would take forever and the resulting files would be much larger. Unless you know a tool that make the conversion automatically, with no quality loss and no big difference in size. Then I would ask you to point it to me asap please

Another example: Picures you collect around the internet (Cabinets, marquees, CPOs, etc...) are all in JPG too.

See what I mean? When you have just a few games, you can convert it easily, but when you are talking about thousands of files, it makes sense to let them in their original format (jpeg). Much more spreaded than PNG and if well done, the compression loss is really insignificant.

It is not a problem, it exist enough tools with a batch function, so you can convert a bunch of pictures at once.

You are quick... Please read my edited post above

I agree that space is no longer a problem these days, where larger HDDs are quite cheap. I just would like to know which program is the best to do such conversion automatically. Tell me which one you guys are using and I will give it a try.

Thanks

I use Irfanview with the plugins pack on Windows...

I would tend to agree that jpeg support is probably helpful, especially for flyers.
