- melodeath666, on 08/29/2008, -0/+36This was SO called for.
- facelesscoward, on 08/29/2008, -2/+27But the next version of Flash will natively support rudimentary 3D.

Anyway, carry on. - o0joshua0o, on 08/29/2008, -2/+21I'm a 3D person too. This morning I played a driving mini-game on the way to work. It had amazing graphics, but the gameplay sucked.
- jakethelake, on 08/29/2008, -0/+15I applaud you.
- NickFury, on 08/29/2008, -1/+13From what I understand the technique they're using isn't that different from the one already being used in Crazy Bump:

^ Pretty handy tool for texture artists, if you haven't seen it already. - DLuckyE, on 08/29/2008, -0/+11Try reading before posting, their technique is what is used to create a bump map or parallax map or whatever you want to use.
- jakethelake, on 08/29/2008, -0/+9That's what I thought as well.
- 5xSTUN, on 08/29/2008, -3/+12I still can't help calling it "Macromedia Flash."
Of course, it took me a few years for me to stop saying "Aldus PageMaker." - SkippyDoorknob, on 08/29/2008, -0/+6ERROR: Texture Overload
- veins, on 08/29/2008, -1/+7lol i see what you did there, with the Im a 3D person too ... that took me a second
- T440, on 08/29/2008, -0/+5You're getting dugg down, but I think you might have stumbled across an amazing idea. With this technology, you could simply take 2 photos of yourself, one with flash and the other without, then let this software create a realistic avatar of yourself for 3D porn games. You could masturbate to yourself having sex with yourself.....weird
- disrupter, on 08/29/2008, -1/+5Only useful for up close surfaces
- petrikigor, on 08/29/2008, -0/+4What, may I ask, is a 4D texture?
- Iatethecrayon, on 08/29/2008, -0/+3Ditto. i thought this was an article about papervision or something.
- SSUK, on 08/29/2008, -0/+3It should have been supported in CS3. You can do all the mathematics for 3D in flash and you could do so since Flash MX (7). Why it hasn't been adopted natively yet is beyond me.
- WillyWonka, on 08/29/2008, -0/+3It sounds like it generates a black and white height map. From there you can use it to move the polys, displace, or bumpmap it.
- DLuckyE, on 08/29/2008, -0/+3For those who want to know more, there is a bit more detailed info here http://aig.cs.man.ac.uk/research/daedalus/hallucin ...
- Iatethecrayon, on 08/29/2008, -1/+4I'm a 3D person. This seems kind of neat but I wish they made a direct reference to the "software" they're talking about that does this.
"Software then compares the brightness of every matching pair of pixels in the two images and calculates how much of a pixel's brightness is down to its position, and how much is due to its colour." - aladrin, on 08/29/2008, -0/+3They wrote it themselves. It's not like they had an off-the-shelf solution for this. They reference as much of it as they're willing to let out at the moment.
Wait a while and some enterprising geek will write an open source version for everyone to play with. - Iatethecrayon, on 08/29/2008, -0/+3They usually talk about what the software is called at Siggraph. The article seems too general.
- ITgirl25, on 08/29/2008, -2/+5I so want to try this on my granny.
- HueytheFreeman, on 08/29/2008, -0/+3My understanding is that photosynth works from many different photos from different angles, compositing them in 3D. Here the photos taken are at the exact same angle, just one photo is flash-lit and one photo is taken under normal lighting. The images are then subtracted in a manner that deduces both the depth of the elements in the image and the lighting.
- maninalift, on 08/29/2008, -0/+2Trying to film with this technique would give all the "actors" seizures
- PhoenixAvatar2, on 08/29/2008, -0/+2That seems so obvious! Has this really not been thought of before?
- arcticblue, on 08/29/2008, -0/+2Sorry pal, that's still 3D.
- maninalift, on 08/29/2008, -0/+2read the damn article, or failing that watch the video.
- PhoenixAvatar2, on 08/29/2008, -1/+3Depends on how bright the flash is and anyways, once you get a certain distance away you can't really tell the depth with your eyes anyways. Extreme example, but the only good one I can think of, all the stars seem to be fixed on a dome, even when some that you can see are many orders of magnitude further away from one star than that star is from you.
- redbytex, on 08/29/2008, -0/+2'Crazy Bump' has been doing this for years.
- maninalift, on 08/29/2008, -0/+2totally different thing. photosynth works using many different photographs and I believe is designed to reconstruct large-scale structure whereas this technique uses only two photographs taken in quick succession from the same angle and reconstructs relatively small-scale variations depth (ie texture)
- mrmiggidude, on 08/29/2008, -9/+11Ahhhh. I get the title. I see what you did there.
- h0ly, on 08/29/2008, -0/+2"A new technique can reconstruct the depth of a surface simply by taking two photos of it"
Bump mapping is not the reconstruction of depth by taking photos, it's rather a rendering technique:
"'Bump mapping' is a computer graphics technique where at each pixel, a perturbation to the surface normal of the object being rendered is looked up in a heightmap and applied before the illumination calculation is done" (wikipedia) - takeo1775, on 08/29/2008, -1/+3Anyone notice the ancient penis character?
- npsken, on 08/29/2008, -0/+2There's a video...
- JazminMillion, on 08/29/2008, -0/+1http://www.flickr.com/groups/3dr/discuss/721576070 ...
Here is one I did with my D3 - JazminMillion, on 08/29/2008, -0/+1I did this one on my D3 today.
http://www.flickr.com/groups/3dr/discuss/721576070 ... - inactive, on 08/30/2008, -0/+1Er...the whole idea is to just use the technique to create a 3D model, which you then animate with computers.
- daveloper, on 08/29/2008, -0/+1crazybump use normals wich is not the same at all...
- rowlodge, on 09/01/2008, -0/+1looks like they could turn up the contrast do do the same thing but shadow and lighting is important in movies, i wonder if this can be done to make them even more economical?
- 3Dimka, on 08/29/2008, -0/+1they are actually developed a new simple method for generating bump maps, by a difference between 2 photographs, one of which is taken with flash
- sab0tage, on 08/29/2008, -0/+1It's clever, but it doesn't look as accurate and there's lot of manual manipulation involved.
- aolshove, on 08/29/2008, -0/+1I don't think CrazyBump is doing the same thing. The results look 3D but I think it's just simulating 3D textures for use by graphics designers, etc. This technology creates actual 3D models that can be used in games with actual depth data, not simulated textures. Consider that if they had used this technology in Half-Life (or whatever), when you walk up to a brick wall, you wouldn't see the pixelated image of a brick wall but you'd see an actual brick wall with depth and mortar ripple between the bricks. I'm a CNC guy and got all excited about scanning models for CNC milling but the video indicates that this technology is good for games and simulations but does not have the accuracy of laser scans for high tolerance milling. :-(
- ZeNiTH456, on 08/29/2008, -0/+1Animated texture? 4th dimension being time. I don't see how this project could possibly be a step closer.
- dinostabOMG, on 08/29/2008, -0/+1Precisely - I do recall reading about it years ago. It didn't take off because it didn't result in practical models. Maybe the big difference this time is that that's improved.
- dinostabOMG, on 08/29/2008, -0/+1Also not especially a new technique.
- mcbarron, on 08/29/2008, -0/+1So...
Add a strobe light and a video camera capturing two frames per strobe flash (so we have a flash/noflash image), and let's make a REAL 3D movie.
Imagine being able to take one movie, then see it from multiple angles in real time playback!! - inactive, on 08/29/2008, -0/+1I've done 3D before using actionscript, but i think accelerating it would be much better >_>
Also, I think there was a way using acceleration already but it didn't do perspective correctness or something - I don't know i just used custom math with shapes. - Kakemonstere, on 08/29/2008, -0/+1Oh damn, that is nice. Thanks, will become handy :D
