    Blended - Curved Screen

    in Entertainment

    Posted

    Need help with the next step here.

    I have a 12'x 40' drawn with three projector blended. I want to convert this to a curved screen of the same dimensions. I have drawn the ideal arc for the curved screen and extruded it to the height of the original screen surface.

    You will see the original screen bisecting the extruded arc. Ideally, I would like the extruded arc to replace the straight screen. I feel I am approaching this the wrong way or I'm missing a basic function here... so I'm asking for input.

    Would I be better served creating a cylinder and trimming an arc out of it's inner face? Can I define this object as a screen surface?

    Look forward to your input.

    Thanks in advance.

    blended screen trouble

    in Entertainment

    Hey Andrew, I just thought of a good add-on. A "Show Throw Distance" option would be helpful. It would report the distance from lens to screen. I'm always drawing in that distance anyways.

    Jeff, you are on the right track. Gotta keep in mind that changing a 4:3 projector to wide mode doesn't help you at all. The proj needs to have a native 16:9 chip in order to squeeze the additional width without needing additional throw. Asking a 4:3 native chip to fill a 12'x21 really means you are asking it to shoot at 15.75'x21' in wide mode.

    blended screen trouble

    Jeff, I wish I found this post before your deadline. Hope you made it.

    Using the blended screen tool in Spotlight 2010, I was able to make a 12'x21' using two 4:3 projectors. I found that the "insert projectors" button acts more like a refresh button while the "Update" button refreshes screen features. Area Horiz Count is your friend. Update that value and hit Insert Projectors.

    Single 1.38 lens on a native 16:9 is 29'-39'

    Dual Blended 1.45 on a native 4:3 is 23'-30'

    [based on Barco TLD 1.45-1.85 (4:3) / 1.39-1.87 (16:9)]

    Your overlap is 11' and you've got 704 pixels of blend. You can save about 9' vs a single 16:9 native projector.

    Any shorter of lenses and the blend can become troublesome. Blending 0.8's and .73's can be done but it is time consuming. Particularly useful if you need to task a projectionist with a long and arduous job.

    HTH,

    Meyer M'elodie DWG Import C++ Runtime Error

    in Troubleshooting

    Posted

    I'm am having trouble importing this manufacturers curvilinear array speaker. I can import the 3d dwg and save the file as a .vwx. But then I relaunch the new vwx I receive a "Visual C++ Run Time Error" and forces an immediate VW shutdown. Would someone be able to re-create this error to check if the problem lies on my side or the source dwg.

    WARNING. WILL FORCE QUIT VECTORWORKS. SAVE DATA BEFORE IMPORT.

    Thanks in advance,

    Blended Video Screens

    in Entertainment

    I would like to be able to have a 10'x30' and a 17.5'x85' rear projection screen as an option within the "create screen" feature. The catch is, I need to be able to choose either three, four, or five projectors in this blended application.

    As far as I can tell, spotlight limits me to only converging two projectors at once. There is no support for blending of multiples projectors. Having the features that are available in a screen's object info palette would be a huge time saver when it comes to setting lensing, cone, overlap, rigging, etc.

    Can I build a custom screen from scratch and make it a resource, then define that resources as a screen object?

    Any help or insight would be greatly appreciated.

    Curved Truss Hanging Angle

    in Entertainment

    Posted

    First poster, long time lurker.

    I need to change the hanging angle of a curved truss. Tried switching to front view and drawing the curve but it lays flat on the Z-axis. Tried rotate 3D along z-axis on object center while in top plan, but no dice.

    The goal is to show a ground supported truss arch.

    I guess I need to change my working plane and re-draw the truss forced to that plane but I do not know how to do that.

    Thanks in advance,
