Trees, Hills, Mountains, and Clouds are at different z-position…Here is a screenshot of the Top-Camera-View:http://img824.imageshack.us/img824/8711/topview.pngI am using two parallel cameras (Animate 2 (not Pro)).Setting the x-position about 0.2 points apart…Experimenting with Cinema 4D using 2/3 Cameras with a shared focal-point,(explained in the tutorial by Matthew O’Neil)The focal point is set to the character, while the cameras are moving constantly around…If you like, here is the result:http://web.mac.com/nolan.scott/Gallery/stereoscopic_cinema.htmlRegardsNolan
you need to pull the trees back onto the same z depth as the hills is you want to truck in and out otherwise the trees will "float"It is a limitation of the method in standard animate.That last one worked really well. I was suprised cause I could barely see the red blue lines without the glasses but it looked good with them.What sort of post processing did you do to join your images?
Using Final Cut Express HD 3.5.1…Applying your composite technique:Next step, I might have to pick up some red/blue glasses…RegardsNolan
Well i guess the advice worked out well then! I liked that one the best cause the effect was more subtle which in turn meant there no confusion between the left and right eye (which sometimes casues double images).The best way to get red and blue glasses if you can’t find a shop (which i could only find online and couldn’t be bothered waiting) just to the newsagent and find a cheap magazine/comic that comes with them free. If you cget more interested you will probably want to order a plastic pair.
Okay I am now totally convinced the numbers in the guide are wrong.Lilly you can correct me if I am way off.If the Camera is 12 units back each of the Left and right 1 unitusing tan inverse (1/12) gives 4.76 degress approx.This means the numbers given in the tutorial end with an incorrect focus point which is much closer than the tutorial intends.How exactly do you caculuate the placement of the fieldcharts it states 11.5 but I don’t know how you came about that number.Should it be the distance of the camera back - 0.5 * translation of cameras?I am trying to make a robust script so you can set the angles as you want. I also then plan to try and do the adjustments with a script rather than manually.With some experimenting I found for the camera back 12 units you need about 0.01-0.06 units translation depending on how deep you want your effect to be.The numbers in the tutorial are just so unrealistic IMO. Although i am happy to be corrected and told i am doing something wrong.
TheRaider, We are verifying the documentation right now to see whether there are inconsistencies. I will post here our results when they are available.~LillyToon Boom Support
Thank you, much appreciated.(and welcome back if all these posting means you are back!)
If someone is interested and should have some time left…Here is a Stereoscopic 3D discussion, 1½ hours long (yes, 90 minutes)with Kai Pedersen and Rick Barrett from Maxon at Cineversity:http://www.cineversity.com/live/index.asp?ondemand=flv_9a878bf0-5a1e-4fbf-ae5f-cb66bc5dc5a1(please copy and paste the whole link into your browser)Even it’s Cinema 4D centered, the discussion explains a lot in general,and might be helpful to anyone interested in the subject…If still interested…, some more information:http://www.youtube.com/watch?v=2zXHINosjfwhttp://www.digitaltutors.com/09/training.php?cid=26&pid=315http://davidshelton.de/blog/?p=163RegardsNolan
Hey Nolan and the Raider,Thank you for the links. I have just read your entries with great interest as I am about to embark on a stereoscopic 3D project of my own. I watched your films with my own copy of the red/blue glasses and I do get the sense of depth.I would like to ask, have you tried to put in a depth of focus effect? Where objects in the immediate foreground as well as background elements in the distance are in softer focus than at the center of attention? The focus on all levels in your films looked very sharp, I just though a blur effect on the background and elements out of the center of focus would help sell the 3D effect better.Cheers!Jean
Hi Jean,I am still in the very early stages of experimenting with stereoscopic 3D…Animate 2 (not Pro) offers just one parallel camera at a time… no animatable focal-point…So, I rendered two camera-passes, setting them about 2 points apart…My experiment with Cinema 4D using two cameras with a shared animatable focal-point,produced mixed results… Everything before the focal-point seems to be appear more or less in front… getting the focal-point in the right position seems to be critical…?Your excellent idea, applying some “depth of focus-” or “z-blur-effects”, made me experiment a little more with those effects…If you like, here is a stereoscopic “blur-effect” render test with Animate 2:(two parallel cameras with an offset of 1.5 points)http://web.mac.com/nolan.scott/Gallery/stereoscopic_blur.html(the original resolution is 1280 x 720 pixels, if you like to download the file)) All layers have a different strength of blur applied…Except the green trees, flagpole and the hills they are standing on… RegardsNolan
The samples I put up were more when I was trying to fix/wasn’t sure what I was doing so don’t pay much heed to mine as a sample of quaility. I was more worried about getting the cameras set up correctly. When you change the focal point you have to rotate the left and right cameras which can be time consuming (that is why i wrote a script to do it for me)Adding blurs should be a standard part in the same way you would use them normally. Just depends on the effect you were going for. If you have your cameras set up correctly you should be able to even do motionblur in 3D and so on.I plan to do some tutorials on this(for both animate and pro) but I just want to be 100% sure I am right (I am awaiting lilly/support to check the numbers in the toonboom tutorial are incorrect because if they aren’t then clearly I don’t understand things as well as I think i do). I don’t want to be telling people the wrong thing 
I like the new test, indeed it’s a different animal when you are working with separate cameras.From what I can gather, stereoscopic 3D does not have a single formula to it, even in Maya. There will be trial an error, but I feel that the tutorial they have here is a good basis or starting point. I imagine Lilly will have a definite answer about the numbers and yet, a further and different test might make these numbers off again. It is more an organic (and time consuming) process to make it worthwhile.Cheers,Jean
Did you get the tutorial to work? ( i only ask because I think i was the only one who attempted it on these forums so I don’t have anyone to say if they could get good results from it).Yeah there is a good variety of numbers which could work (and i have allowed for that) but once you fix your focal length and distance of cameras then the angles should now be fixed (there should be definite wrong and right angles). Unless i am mistaken, which i could be, it is those angles I can’t figure in the tutorial.I think being cartoon type animators you have a lot more freedom in picking your numbers.
When I did the calculation I got the same value as you did for the angle. You’re right that if you have a fixed distance from the camera then you should be able to calculate that angle exactly, and if that distance is 12F, and the camera is 1F away, then the angle in the doc is wrong. I think the reason that no one has run into this particular problem before is because this value is simply a starting point. Later on in the tutorial they have you line up the cameras visually using the field guides. If you do so, then naturally you will correct that to the correct angle at that time. However I understand that since you want to do your setup with a script, you want to input the correct values at the outset. As far as I can tell, your math is correct.I have forwarded the comments to the documentation team for review. ~LillyToon Boom Support
thank you. Part of what confused me is with those numbers the field charts pretty much perfectly line up with “1” on the main field chart so I initially assumed that was right.I knew it was just a numbers issue and the actually process of the tutorial is good.
Just thought I’d step into this conversation and share this link I found that might be of interest to you guys, It is Stereo 3d channel and there are some pretty good 3d videos and resources posted on there. [url=http://vimeo.com/channels/stereoscopy]http://vimeo.com/channels/stereoscopy Maybe one of those guys maybe able to offer some tips?
