Since Dan is very busy working on it, I'll tell everyone about his 3D engine project.

He found a 3D engine for the GBA (and other mobile, low powered systems) called Yeti3D.

He has made considerable alterations to it, and there are many more to come. This Page is a sort of visual history of it's development, in reverse chronological order.

Things still to do:
1. Make it 3-D (as opposed to merely 3D)*
2. Increase Speed
3. Add features (and replace features taken out during conversion, such as lights.)
4. etc.

*Note that I use the term 3-D to refer to a stereoscopic image or system thereof, and 3D to refer to a polygon-based image or system thereof which produces only one image e.g. "next-gen" consoles.

This could make for some very cool games, if certain issues can be worked out! Keep up the good work, Dan!

It's not really a "tutorial" per se, but I've been updating David Tucker's VB technical document. Some day I might release it...

I'd be glad to help out on the "supa-dupa" doc, though! ;)

1) Check the voltage at the end of the AC adapter.
If it's not 6-15VDC, get a new adapter and/or go to step 4.
2) Check the voltage at the terminals (on the tap) that connect to the VB pad.
If it's not 6-15VDC, get a new tap and/or go to step 4.
3) With the pad's switch on, check the voltage across pins 5 and 6 on this diagram:

Open in new window


If it's not 6-15VDC, get a new pad and go to step 5.
4) If you can't get a new adapter or tap, perform "trafo mod" and proceed to step 5.
5) VB ON!

Hope that helps...

PS: The VB also requires a certain amount of current to run. I'm not sure what the minimum is, but 800mA to 1A should be a safe bet, even with "other stuff" attached (e.g. possible future expansion devices, etc.)

Here is the form I want the VB2 to take:

1) Console (i.e. not "portable.")

2) VGA output standard, _maybe_ (HD)TV as an _option._ Am I the only one that realizes how _cheap_ old (S)VGA monitors are?!?!

3) Anaglyph mode standard, shutter-glasses and (eventually) HMD/dual-projection as add-ons. Anaglyph glasses are _free,_ (!) which solves the "Other people can't play with me/watch me play!" argument!

4) Use GC controllers, (including GBA linking) to SAVE ME (the consumer) MONEY!

5) Networking would be cool, but not really necessary. VB link port a MUST! And, INCLUDE THE FREAKING CABLE, THIS TIME!

6) Stop trying to prevent hacking; it won't work! Make it open, instead!

Thank you for reading. Please pass this along to anyone you know working at Nintendo.

Sincerely,
RunnerPack

I also think it's a nice idea (in theory) but it's slightly flawed, and not exactly new...

One of Mr. Yokoi's other inventions, the "Game & Watch," used an LCD sandwiched between a reflective background layer and a transparent foreground layer. Both of these layers had images printed on them, making a nice "parallax" effect such as you described. Granted, in your system there would be more, and they would be active, rather than fixed, but still a similar idea.

Also, unless you also go by "pmboy2000," this guy thought of it, too: http://www.halfbakery.com/idea/3D_20Kube

As for using LCDs: Though I'm not 100% sure, since LCD's use the polarity of light to decide whether the light is transmitted or blocked, I don't think you can even stack LCDs. Even if you can, it would have to be the transmissive kind, not reflective like the GB(A) panels. Otherwise, not enough light would get to the reflector (and back out) to be able to see anything.

And since even the most expensive transmissive LCD passes much less than 50% of the light, this probably wouldn't work, either.

However, there do exist so-called "holographic" displays which are transparent, but which don't use polarization to achieve the image. While not yet (AFAIK) commercially available, they would not only allow this display technology, but also increase both the total number and visual quality of the layers, because:

A) They use an extremely thin refractive coating which can be placed on a similarly thin transparent sheet to achieve their effect, and:

B) They use laser interference rather than transparent metal electrodes to control the pixels.

I'd like to put some links here, but I can't find any. It seems like I first read about it in Popular Science, though...

Anyway, I hope you can figure it out. It sounds really useful and (potentially) inexpensive.

As an aside, I recently found out that most LCDs polarize green light at one angle and red and blue light 90 degrees from that. Apparently, if you look at a green/magenta anaglyph (most anaglyphs are red/cyan) on an LCD (or an LCD image projected on a polarity-preserving screen) through glasses made of crossed polarized lenses, you can see in 3-D, but with much less cross-talk than with regular colored filters.

As soon as I can get some polarized filters, I'm going to try it on the GBA. If it works, I'm porting VB Wario Land!

Later,
RunnerPack

1) KR155E tried changing the font sizes to no avail... I'm not giving up, though ;)

2) As you can see, we've begun replacing the checkboxes with the VB Wario Land rocker switch, but it still needs polishing.

This thread can be a useful feedback mechanism, to let the PVB team know how the forum can be improved upon.

1) Everything should use relative font sizes, especially the message bodies.

2) Although the red is getting a _tiny_ bit annoying ;^) it might as well be complete. To this end, the checkboxes ("Add signature..." etc.) should also be red/black. (Since you can't do this with CSS, I'm working on a javascript version.)
