Crazy Homeless Guy Posted February 11, 2009 Share Posted February 11, 2009 Anyone go see Coraline yet? Pretty sweet. They previewed a couple of animated 3d movies that will be released throughout the summer. The majority of the movie was done the old fashion way, with stop motion animation, and hundreds of models. It really is a testament to the art of the craft. I even read a comment about someone online stating that it was the best computer animated movie they had ever seen. I thought about letting them know that most was done by hand, but didn't feel like registering. Anyway, I grabbed about 4 pairs of glasses that people left in their seats. If I have some free time, I might mess around, and see what I can do with animating a building in 3d. Link to comment Share on other sites More sharing options...

It be funny to start making our Exec's walk around in those ridiculous looking glasses as we laugh at em behind their backs. Link to comment Share on other sites More sharing options...

The clients we have now grew up when 3d glasses were starting to have their hay day. It would be both exciting for them to see their building like this, and reminiscent of things from their childhood. Which gives an emotional hook.

Camby1298 Posted February 11, 2009 Share Posted February 11, 2009 I agree! All we need is a field with a large drive in screen and have the clients sit in their cars as they view the rendering. Ill roll up in Roller skates and see if they need anything to drink Link to comment Share on other sites More sharing options...
Justin Hunt Posted February 12, 2009 Share Posted February 12, 2009 We did it recently, whilst I wasn't in the presentation apparantly it was funny to see the suits wearing the 3D glasses. Worked quite well I might add, they enjoyed the experience. jhv Link to comment Share on other sites More sharing options...
Frosty Posted February 12, 2009 Share Posted February 12, 2009 I also did some experiments with it both in 3D and using an SLR. The 3D actually works quite well. The camera is a lot harder because of the difficulty acquiring the correct images. There are a number of tutorials online for how to try it yourself, but the basics are very simple. Two cameras are placed in the scene beside each other - one to simulate each eye. The rendered output from each camera is composited into the correct channels in PS or AE. You end up with a screwed up looking red/blue image or video that when viewed with the filter glasses is perceived as 3D. Link to comment Share on other sites More sharing options...
Chad Warner Posted February 12, 2009 Share Posted February 12, 2009 That sounds like it would be a fun thing to do.I'd love to see some examples if anyone has some. Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted February 12, 2009 Author Share Posted February 12, 2009 The 3D actually works quite well. The camera is a lot harder because of the difficulty acquiring the correct images. The ease of doing it in 3d compared to real life became evident in the movie. The real footage that was shot was beautiful, but in terms of the depth, wasn't able to match the pieces that were produced with CG. Meaning that you felt like you could reach ot and touch the CG items at times, where as the real footage still felt contained within the screen. ....even though it still had a 3d effect.

dbibb Posted February 12, 2009 Share Posted February 12, 2009 I haven't seen Coraline yet, but am very excited to. A couple of my friends from school worked on it - some very talented stop motion artists. They also did some animation work on my student film (http://www.glargandfritz.com). Did they use dual SLR's on Coraline to get the 3d effect? Link to comment Share on other sites More sharing options...

Just had a look online but could only find tutorials on the B-movie style red-and-green glasses type 3D. Anyone know how the full colour stuff (like Bolt & Beowulf) is produced? I've always wondered what it'd take to use the technology for arch vis... Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted February 16, 2009 Author Share Posted February 16, 2009 I haven't found a lot yet either. But, ...the name on the side of the glasses that I have from the movie is RealD. Searching in Google with that term may help narrow the results. Link to comment Share on other sites More sharing options...
Frosty Posted February 16, 2009 Share Posted February 16, 2009 The very basics that I remember are quite simple. 1) Two identical cameras side by side to simulate your left and right eyes - name your cameras as such. BOTH CAMERAS HAVE THE SAME FOCAL POINT! This is critical. 2) Render out two grey-scale still images named left and right. 3) One image gets pasted into the red channel of a new PS file. The other image gets pasted into the green and blue channels. I can't remember which is which and I don't have any glasses here to check. I have missed a few things, but that's what I can remember. Hopefully somebody has some time to tinker and post a few attempts. Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted February 16, 2009 Author Share Posted February 16, 2009 I think the technology being used in the current iteration of 3d movies is different than what has been traditionally used. Not sure because I haven't found a great deal of information, but I am willing to buy you a drink if I am wrong. Link to comment Share on other sites More sharing options...
Bwana Kahawa Posted February 16, 2009 Share Posted February 16, 2009 Indeed - it'd be good to see. From your description, that sounds like it'd put crazy coloured haloes on the image - much like the old style red-and-green stuff. Watching a few seconds of Beowulf without the glasses, the 3D image was still full colour, just weirdly blurred. So for different lenses in the glasses to pick out different aspects of the blurred image suggests it's more than the just the image - perhaps some particular method of projection?

Crazy Homeless Guy Posted February 16, 2009 Author Share Posted February 16, 2009 To the bare eye, the lenses appear to be the same on both sides of the glasses. I am attaching a photo of them. Also, Wikipedia provides interesting information.... http://en.wikipedia.org/wiki/Real_D_Cinema RealD however uses a single projector that alternately projects the right-eye frame and left-eye frame, and circularly polarizes these frames, clockwise for the right eye and counterclockwise for the left eye, using a liquid crystal screen placed in front of the projector lens. Circularly polarized glasses make sure each eye sees only "its own" picture, even if the head is tilted. The very high framerate, which is 72 frames per second per eye, makes sure the image looks continuous. In RealD Cinema, each frame is projected three times to reduce flicker. The source video is usually only 24 frames per second (which can result in a subtle stuttering on horizontal camera movements). The result is a 3D picture that seems to extend behind and in front of the screen itself. Link to comment Share on other sites More sharing options...
Frosty Posted February 16, 2009 Share Posted February 16, 2009 What I was describing is the old school red/blue version yes. Link to comment Share on other sites More sharing options...
Bullet Posted February 16, 2009 Share Posted February 16, 2009 From what I understand, all new 3d movies are using a new method of polarized images. So there's no more blue and red, instead the polarized lenses on the glasses filter out which set of images are for the left and right eye. You could watch these movies without the glasses (as in the case of my 2yr old son) and it wouldn't look bad, just a little fuzzy at those parts where something is suppose to be really far away or close to you.
