I have found that IART3D is advertising an univerals kit for creating autostereoscopic display from standard LCD monitors: http://www.iart3d.com/Products/Autostereoscopic% 20Display/Auto3D_Kit_Eng.htm I expect that the kit use plastic lenticulat optic corresponsing to the LCD disaply size ... I thing that it can work, I had seen a NEC LCD mionitor modified in similar way. The key questions: Does anybody have experiences with this kit ? Does it produce at leas a bit acceptable image ? |

Yes. It works if your LCD monitor has exactly the dot size specified by the product, and willing to accept that your horizonal resolution got cut in half. I sent them an email and see how much the auto3d kit is. It sounds fishy if a company's website does list the prices of its products. |

BOPrey: Let us know the result. My Toshiba Satelite notebook hase 0.28 mm pixel distance = I do not fit in the 0.297mm (for 15") category :-( |

I read "More than seven views for multiple-viewer wide-angle use" so I cannot expect the total image info cut in half ... but in 1/7! You need 7 views: no 2-view stereo stuff can be used and a lot of computational power is needed. :-( Giorgio. |

M.H., It is not going to work if the dot size does not match exactly. This is just how lenticular works. To find out more, to a simple of the net. I don't have any link, sorry. BTW. You don't have to buy the kit from this company. There are more than a few companies you can find on the net that sell custom lenticular sheets. You just have to find out what the dot size of your display is and convert that to number of lens per inch. They will be happy to make you a few sheet for 5 to 10 bucks each. |

To Giorgio: Calm down! I'm sure by "seven views' that they are simply refering to the number of "sweet spots" from which a stereo view can be seen! Otherwise, each lenticular "cylinder" would have to be 7 pixels wide! Unless they use a diagonal sytem as Philips did? To "BOPrey": PLEASE share the specific manufacturer who offers a "few" CUSTOM pitched lenticular screens for 5-10 dollars each!!! I am waiting with money burning a hole in my pocket!!

John, I use to have a link to the company that sells 8 1/2 by 11 sheet for $4.99 when I was working on my autostereo screen project, but I lost the link. However, try this to start. http://www.depthography.com/screen.html |

John, yes, I expect a 7-pixels wide cylinder because "7" can't be divided by anything and that's why it can't be something like Philips (9=3x3). But this can't be true and you're probably right. Giorgio. |

In case you guys want to know. I got an email back from that company. The autostereo kit is $199.00 US & shipping, and it will be available in two months. |

$199 is not so cheap I will buy "rabbit in the bag". They should publish exact optical scheme of the lenticluar sheet. Reduction of horizontal res. to 1/7 looks to drastic. But I find a cheap experimental conversion kit for LCD monitors a good idea anyway ... |

I received a reply also: "Dear Mr. Billingham, We offer "Auto3D Kit" for Notebook PC and LCD Monitor. For Notebook PC package, its sample reference price would be US$299 (17"), US$199 (15") and US$159 (13.3"). For LCD Monitor package, its sample reference price would be US$349 (17") and US$249 (15"). But, they are not available now until two months later. The shipping cost to USA by air parcel would be US$20 for each kit. We don't just sell the lenticular screen without our software packages. Best Regards, JG Wang" If you look at their site, I think it is pretty clear that they mean "7 view points" not "7 pixel intelacing" Perhaps I can 'shrink" some slightly too large pitch lenticular material in the oven??? Actually, I'm quite happy with my homemade autostereoscopic barrier laptop! Best Nerdly Wishes, John Billingham |

John, care to share you secret of making autostereoscopic barrier mask for a LCD screen. |

A simple answer: "INK JET PRINTER" For a slightly longer answer, join the Yahoo group "lenticular3d" and download my little "barrier kit" from the files section. There is a short barrier animation there also. Let Me Know How it works for you? John Billingham |

Yes. I be damn. Sure will check out lenticular3d. Question, doesn't the thinkness of the transparency has to have some kind of relation to the dot size of the screen? |

Depends on the situation. I favor a 30" viewing distance (enough that the "screen" isn't too obvious) the pixels are approx 1/100 " wide, and I like 1/10 " thick "spacer" between the pixels and the "barrier" But this is for a vertical 8" x 10" barrier laptop screen. Too "thick" a spacer, and the viewing gets very "touchy" There is some very obvious geometry at work here. John Billingham |

John, Would you be kind enough to email me those two files in the lenticular3D group. I just have no luck downloading them. My email addr is kx2us@yahoo.com Regards |

John, finally able to download the files from the group. Question for you. You print the barrier on an inkjet. Is it possible to print the barrier on a laser printer? |

John, I'm interested in trying your Barrier method but the files are no longer available at the yahoo lenticular 3D group, can you post them again or email them to: cheers, Willy |
