    The first time that I saw 3d video advertising on the walls like a real part of any living creature Which were displayed on the street, the following questions came into my mind:
    1. Which kind of Projection have ability of showing this movies?which Projection should be used for showing the film on great large scale, like (10m × 8 m) ? How is the distant relationship between Projection & the pictures ?
    2. What is the software that can help to make up this trailers & what applications i suppose to use?
    3.Is there any special workshop holding somewhere in the world or not?


    Thanks:)

    1) all projectors will allow you to project video. there are a lot of factors to be considered when speccing the right one for the right job. what time of day? is there other light to interfere with the projection? whats the distance between the placement of the projector and the area being projected upon?

    2) what you make your video in is entirely your own choice - after effects, premiere, final cut, motion, c4d, Max, maya and many other choices besides. generaly the software used to create and the software used to playback are not the same ( there are exceptions though, for instance: MAX / Jitter / vvvv / processing ) popular choices for playback are modul8 and avenue with extra plugins liek madmapper and ir mapio expanding on the basic abilities. again though, there are far more options than mentioned.
    http://www.softwarevj.com/ can help you find the aps that fit your needs soo you can narrow down the choices.

    3) there are workshops in many countrys, but generaly one offs and not regular weekly events - "video mapping" is the term you need to search for

    for making my knowladgecomplate

    Thank you very much , that really helped and actually was one of the best answers that I have ever heard .
    But :
    I was wondering if you could give me some more information a bout questions below :
    First of I wanted to ask you a bout some informations . the informations are about some special kinds of 3d projectors which could help me to get involve with my exprimentations in my own workshop . projector performance and also prices is very important for me . actually I want to buy a perfect projector with high performance and low price .
    Secound of all , I wanted to know the hole price rate for any kind of3d projector, I mean different brands and models . wich one has the best ability in expriment and works wich happened in offices and labs (small size works)? Wich one has better fit back in big sizes , real works and programs ? is there any diffrence among this two kind of activiteis and the 3d projecter that I have to use ?
    For last question , I think by the time you gussed that I am not specialist in this field of art . (its pure art as I see) . I was wondering if you could guide me for going to some reliable and academic workshops wich are working expertly in 3d mapping and 3d projection . the place of class Is not that much important for me , but the knowladge & time is . its better for me to go to this class a bout six mounth later. Because I am a foreigner , I prefer to have an net baise enrollmente . I mean I want to pay my fees and tutation with net and make every thing , like hotel and this things ,okey from my owne country and then travel to the place that class is holding . I don’t want to be there and have nothing .:)..
    With special thanks great frinds of mine .
    Sorry because of my mistakes in writing ,

    There is no such thing as a '3D' projector.
    The content is made in 3D and projected like any other content.The way the eye perceives the projected image by the (current) use of wearing correction glasses in front of your eyes gives the 3D effect.
    There is of course the various 'peppers ghost' systems which involves a sheet of clear plastic as the projection surface giving an effect of whatever is projected being there in the 'real'.
    If you are thinking of projecting onto a 10m x 8m surface then realistically you are looking for a projector of a minimum of 15k lumens and at a cost of something in the region of UK Sterling 20k+ and then you would need to buy lenses. Here is an example http://www.memory-express.co.uk/p/603044?utm_campaign=froogle&utm_source=Froogle&utm_medium=Lead
    Mostly when projectors of this size are involved they are hired in specifically for specific jobs.

    with special thanks to MR PC PROJECTION
    Here , I have puted a movie link for you Mr PC PROJECTION . you can see the movies . I don’t know the real name of this things and I just called them 3d projectors and 3d movies but this things are real 3d . you know , there is not any need for using glasses and sth like that . you can realize that that pictures are pure 3d . maybe I have some incomplate informations but I do know what I have seen .
    I am steel waiting for some body whom can give some answers to my questions . and of course I want to know a bout workshops in this field . I mean 3d mapping or whatever it is . I don’t know the actual name .
    I think , I had to repeat my questions

    Well I am sorry to have to explain to you once again to you, this time slowly and carefully, that despite you believing those are 3D please take my word for it is a 2D projection of a 3D animation. The glasses reference was to cinematic 3D. Sorry for the confusion I caused but that doesnt entitle you to be rude to me in return. I accept that I didnt realise you have such a limited grasp of how the projections are done.
    There no no courses or workshops that are run regularly to teach these skills. Most of the people that are doing this type of work have many years of experience before attempting something like that This why you arent getting any answers to those questions.
    Please understand if you dont like the answers to your questions that isnt my fault for answering your questions.

    here is a link to a google search for tutorials

    http://www.google.co.uk/#hl=en&suge....,cf.osb&fp=50a948b50ff5e422&biw=1067&bih=737

    and here is another search for workshops but i checked 3 pages in and there is nothing shown for the future

    http://www.google.co.uk/#q=video ma....,cf.osb&fp=50a948b50ff5e422&biw=1067&bih=737

    Oh and being rude isnt the way to get strangers to help you, if you cant even copy my name correctly I do personally believe these skills will be beyond you. See, I too can be rude to a stranger on the internet, it isnt like it is hard or big or clever.

    Indeed and to save our new friend some time here is a link to the post that nails the fakery that is going in the video they are in awe of. I did have it in mind to post your video of the mapping at Marble Arch you did as a good example but lost patience and couldnt be bothered to do anymore searching that 'somebody' else should at least be capable of if they want to attempt something like this!

    Hi again ,
    beyond every thing that I said and things that happend . I wanted to give my special thanks to Mr PC PROJECT . (calling you projection was just a honest mistake cuased by writting projection again and again in my request page.) sorry .
    Again that I should say sorry and ask for forgivness because of what I said but , only for your considration , I am not a prefect english writer or speaker . by the time that I am writting for you , I had to use 2 or 3 dictionaris plus google translate . sorry because of my rudness . It happend just becuse I didnt know the proper words .
    Honestly That wasnt delibrate insulting but it happend . sorry . you will make me happy if you accept my apologize . I am looking forward to hearing from you Dear PC PROJECT .
    One more thing , you should know that my country is in embargo and by cotting . most of the times when I am using forums and sites , I have no choice except using nearest name to my owne country . I mean Iraq . My country name dosent exist in many web sites and using Iraq had became a habbit for me . it wasnt delibratly or for abusing or sth . Its just a habbit , bad habbit I know , that happend . apologize from all members and all people . In our country , such a things dont exist .3D projections , mapping , projectors and people who were expert in this field . This situation makes many problems for me . you can see that i dont have any information a bout this things . but I know that i want to do it . Iwant to work and get expriments . hard work but I will do it . If you let me , steel I have some questions , First , Waht do you mean by Fake PROJECTION? Whats the diffrence among real or fake projection ?
    and for getting basic information and data wich web site has the great archive and can help me to go throught ?
    MR PC PROJECT , your answers are very comlate and helpful . help me

    Yes sorry from me too.Your reply caught me at a bad time.

    By saying the projection is fake is possibly a little confusing to a non-native English speaker. It is a real projection BUT the clip you have linked is one that has been enhanced in post producition and by that we mean it has been projected, filmed/video'd in real time by somebody and then that footage put into an editor and played about with, most likely to give a better impression of how the original looked. In my previous post I linked another post in an older thread (the thread Deepvisual pointed you in the direction of) where SleepyTom had put an unenhanced video of the show side-by-side with the enhanced one and then discussed the differences. It may well be worth some of your time revisitng that link and rereading the post and waching both the videos to see what is has gone on (with the fakery)
    The original conclussion by some real experts on this forum was that the company who originally did the mapping and then posted the video had done so to make potential customers think they were really good when in reality it wasnt quite as good as they were selling it to be. Maybe be a common practise in other industries but not welcomed by the professionals here!
    After a bit of a rocky start I hope you enjoy the forum and find it beneficial and good luck dealing with the difficulties that the regime in Iran may cause you.

    hi
    living in Iran needs some special kinds of PHD . here things are very diffrent . any way thanks . people in Iran all know that we have many frinds that they hearts are beating with us in our big prison here .

    I am not even at primary level . how can I start ?
    I want to start with Basic Informations . elementary things . No matter how easy they will be seen by your eyes but , I am sure things which you have in your memories from first experiments that you made, are the most important & valuable things for me .

    for starting I must buy a projector
    I wanted to ask from every one . please tell me the exact name of some projector Brand & Model for working one small makets or small sizes like 1m*1m
    thanks
  13. USE

    USE Primal Visions

    in order to meaningfully assist, we'll need more info. To start:

    what's your budget?

    Will the projector need to be used during the daytime or under bright lights?

    Will the projector need to be able to project from an angle to the screen or will you always be able to set it up directly in front?

    Will you be projecting from the front or rear of the screen?

    What will you be projecting from: a computer, or dvd player, or something else?

    ... You will also need to think about screens, again, the above questions will affect what kind of solution you'll need.

    I'm so in love with this thread :D

    It makes me wonder if there's a www.pianistforums.com out there somewhere, where people ask questions along the lines of: "I've just heard a 5.1 recording of Mozart's Fur Elise, and I want to know where I can get a 5.1 piano."

    And that people actually give serious responses to such a question.

    I love you vjforums.com, never change!

    there are basically 2 options.

    either you buy a small projector and experiment with the various different methods of masking / warping / aligning the projection onto 3d objects.

    or

    you get at least £20,000 together for your one day show budget and give this money to a professional projection specialist who takes care of everything for you.

    option 1 takes many years but you end up being an expert.

    option 2 is the only way to go if you want / expect high quality results quickly.
  19. rsx.muhammad

    rsx.muhammad New Member

    Thx Tom . Be sure I am not the man who would do the second option. If I want to do things that you have in your first option , I have to buy a projector as you said . Could you just tell me the name of that projector? If my projectors are two or three or more , please dont hesitate to tell ...

    literally anything will do to practice at home with.

    it will make almost zero difference which machine you have so long as it is just for practising at home with.

    I'm guessing that Iran doesn't have many places to buy a projector, so just get whatever you can find locally.

    I've used a lot of different projectors and for mapping purposes there is almost no difference between any of them, until your spending $10,000 on a projector then they are all much of a muchness.

    Ok. In that case I will disregard my being in Banda Shapur or as you may know it Bandar Imām Khomeinī for 3 months as a figment of my imagination. Please dont pressume to come here and telling people what they do and dont know when you obviously dont have the first clue about what I do know and dont and where I have been and havent.

    my experience as a war reporter is that you can always buy everything anywhere regardless of the political situation a country happens to be in, as long as you have the cash ready. I went past a store in sarajevo where you could buy plasma tellies, that was during a time where countless dead corpses where found at the shore of river drina.
    concerning the projector issue, i would say, this is the least problem for our iranian friend here. the major question is, are you expirienced in any of the common motion graphics suites like after effects, cinema 4D, maya?
    if not, no projector in the world will be of any use. the projector just throwes an image to a wall. it wont magically convert anything into 3D. the image has to be composited in a way that creates the illusion of 3D on that specific wall.

    Dont cout it as insulting But, you were only in bandare Imam (International Imam khomeini seaport ). How could you just be this much rude to me ? Pershia has 3000 years of history , 7 really different types of blood , over 30 states , over 80 milion people , over 1000000 citis maybe more (I am not sure)... ,_ and of course many stupid governments , _ We are not what you have been told . Here in Iran we are fighting for freedom . We dont beg for anything . We dont want any support from anyone . You may think we are killers , Gunmans , I dont know ..., You may think that our only work here is planing to fight , starting war , telling lies . You people , when you cant help somebody to be alive again , Just dont break their heart .

    I dont think anything of the sort about people of any other country and you are grinding your political axe on a technical forum.
    What I do think is that the OP is wanting to do something that is way beyond their skill set and the point of this thread has become about trying to get that through to them.
    Thank you for making sure your next post has relevance to that original post and the questions that require an answer and not another political statement as this is a distraction from the topic.
