16:9 Projector and Collage

edited March 2007 in Axon
I have a show comming up that will have 4 DL.2's on it. They are projecting onto two curved panels (two to each panel) that flank a flat center rear projected screen. Please see the image attached for clarification. The center screen will be using a fixed 16:9 Projector. I was wondering if I can use an Axon with the center projector and have the whole screen become a 5x1 collage. I know that there will be some funny blending issues where the DL.2 and the Rear Screen meet, but would this work? Thanks.

    DL.2's and Axon i'm not to sure about.........

    However if this does work...... I'll be hoping to see photos of the event.

    well, the axon is a dl2 without the projector, so there's no problem about using an axon as one part of your collage.. i'm not shure what happens when you put a 16:9 projector on it though.. my guess is that the projector will just either compress the image in heigth, or cut it's sides.. I would guess that you can just shoot wider than the surface with the actual zoom of the 16:9 projector, and compensate for it beeing 16:9 with the keystoning on the axon, when you make your collage..

    -Someone smarter will probably chime in and give you some great advice, if my idea's are wrong.

    Sorry, I should have stated what specifically I am concerned about. I know the Axon is the DL.2 without the projector. What I'm worried about is:
    1) What happens when you hook up an Axon to a 16:9 native aspect projector (I'm working on getting the model name/number from my AV Vendor)
    2) Since I am using the Curved screen collage for the screens on the ends, if I put the center projector into a flat collage, will there be massive blending/alignment issues? (I haven't used the Curved Screen Collage before, I didn't see the steps for the set up in the manual either)

    that about axons beeing dl2s was ment for kris.. but anyway..
    1 i don't know tha answer for..
    2 I'm pretty shure i know the answer for.. I think your situation is great for showing people how wonderful the dl2's are.. You will need to make a big collage first(5) and then with your two left dl2's apply the curved surface.. and then another curved surface on the two right ones..(this will use both of your efx's though..) This is atleast the case if you had 5 4:3 devices.. since i don't know the answer to 1, i'm not shure if that makes it harder/impossible to acchieve. but my guess would be no.. since you can just "shrink" part no.3 of your collage to compensate for the 16:9..


    edit:to claryfy.. there isn't a "curved collage" a "curved collage" will consist of two effects: the collage effekt/generator, and the curved surface effekt

    You may run into a few other issues here as well b/c you are using a combination of rear and front projection.

    Plan on flipping your media 180 degrees on at least two axes (like X and Z or Y and Z) so that your files are playing back in the proper direction.

    Here's an example...you have a media file of water ripples that move from stage left to stage right.

    Well the ones projected by the DL.2s will move stage right to left and the one from the front will move from left to right.

    Apart from this though you should have no problems making the collage.

    Also the newer versions of the manual give a great deal of detail on curved surface support (keep in mind curved surfaces are dealt with on an individual/per fixture manner even when used in tandem with a collage).

    Hope this helps:)

    I forgot to mention though....the axis flip workaround will not work if you have something that needs to be displayed a specific way...such as text (it's either going to be backwards in the center or on the sides...depending)

    Most projectors have a feature for rear projection that will automatically "flip" the image.

    True, but if you set your center projector to "rear" and then use it as front things like text will be backwards.;)

    This mode doesn't actually flip the image over the horizontal or verticle axis. It's a mirror image of the source so when you look at it, it reads normally. They use this mode in classrooms with RP screens for power point presentations.

    Thanks! I didn't know that it was a seperate effect. That would explain why I didn't see it in the Collage Generator section of the manual. I guess I should :rtfm: all the way through.

    (I've always wanted to use the :rtfm:icon, but never had the guts to use it on someone else)

    Exactly, so if you were to put your center projector into a "Rear" mode to try and match your DL.2s you will run into problems with things like text because it will be "mirrored" to be readable on the opposite side of the screen.

    (If you have ever tried to navigate a projector's menu from behind an RP screen you will know exactly what I am talking about)

    This same type of "mirroring" happens when you flip a media file around in DL.2 or AXON 180 degrees on the X or Y axis when using the default 3x4 rectagle object.....you are now looking through the object from the other side, and hence it appears to be "mirrored". Just as if you have walked around behind a projection screen to view it from the opposite side. (Note that you could also change your viewpoint in Global as well to move around behind the object and view it from the opposite side if you wanted to, but now your layer hierarchry will be reversed...1 will be the "front" most layer and 3 will be the "rear" most).

    Not to confuse the issue further, but I mentioned rotating (or flipping) on the Z axis as well because your DL.2s look like they are hung from a truss, whereas your front projector appears to be sitting on ground support (balcony ledge perhaps?).

    This could be easily overcome though by changing your projectors "ceiling" mode.

    It's the same type of thing if you were to tilt your DL.2s in the wrong direction to a projection surface....the image will be upside down. But like I already mentioned if your projector has a "ceiling" mode you can easily reverse this.

    Hope all of this is helpful to you.:)

    Everyone has had lots of good information here so far.

    One more important thing to note is that the Axon currently is locked to a resolution of 1024x768 so it will not natively fill a 16x9 raster.

    Ok, I seem to have lost you all,
    It seems to me if you have a rear projection,
    and set the projector to rear mode,
    the image should be identical to a front projection.
    Right??
    same as setting a projector to ceiling mode...
    I don't see the conflict at all....

    Where is the conflict you are describing coming from, both drew and I seem to be lost on this one...

    My apologies if I am being dense...

    just got back from China... and I see what's going on... the fixed projector IS the REAR PROJECTOR. The Dl.2's are in the front! I thought that by saying "..a flat center rear projected screen. Please see the image attached for clarification. The center screen will be using a fixed 16:9 Projector." people would have gotten that the projector would be the rear-projector since it was projecting on to the "center rear-projector screen". I guess I could have clarified that better.

    OK...makes more sense now...I was wondering why you would want to set the center screen to rear to be viewed from that side;)

    The one thing I forgot to mention earlier is that you can set the DL.2s projector to "Ceiling" and/or "Rear" modes via CMA or from the menu to make this work from the "opposite" side as I originally thought.
