Screen - rosco.com. Rosco Screen A range of projection screen materials, each with special technical properties. All screens are designed for excellent color rendering and good contrast with a wide range viewing cones. Rosco screens are specified by major opera houses and theatres around the world. All screens are durable, washable and inherently flame retardant and should be viewed from the matte side to help minimize the unwanted effects of ambient light. Screens are shipped folded in boxes via UPS, FedEx or common carrier (depending on size). Certain screens can be shipped rolled on a core if specified by the customer. Rosco screens can be washed using a soft cloth and mild dish soap.

Projection Screen - Light Translucent (55" Wide) A slightly opaque, light grey screen for a wide variety of uses. For projection it is ideal for situations with high ambient light, particularly in outdoor installations* because the high light transmission of the screen allows the image to compete with bright ambient light.
Care should be exercised in avoiding the line of sight between the viewer and the projector, however, due to "hot spotting". Light Translucent screen can also be used as bounce drops and diffusion material. • Viewing Cone: 160° • Designed for rear projection • Cold Crack: 10°F / -12°C • Thickness: 7 mil • Weight: 1 pound per square yard • Also available in 110" wide material, call us for pricing • Sold by the linear yard *Screens will degrade when exposed to prolonged UV exposure, expected outdoor life is about 3 years depending on local conditions Basics of Choosing a Screen (opens in new window) Screens are shipped folded in boxes via UPS, FedEx or common carrier (depending on size).
How-To: Make a custom projector screen. The quest tobuild a greathome theater is one of our recurring themes for Engadget's How-To Tuesdays. And as anyone home theater buff will tell you, any HDTV worth its weight in salt will present its viewer with a 16:9 (1.78:1) aspect ratio display, or in some cases, project a 1.8:1 ratio. For todays How-To, though, we're building one of the holy grails of the home theater: a 2.35:1 widescreen.
Yep, that's movie theater widescreen, alright. The most important component is the screen material. Shopping list: (3) 1 x 4 x 96-inch Douglas Fir boards (1) 2 x 2-foot x 13/64 piece of plywood 1-1/8th-inch fine thread drywall screws Staples (3) yards of white curtain blackout cloth Tools: Drill with Phillips screwdriver bit Saw Staple Gun Hammer Utility knife or scissors Our 2.35:1 screen is designed to maximize the materials we purchased. The frame is constructed using theater set 'Flat' construction techniques. 1 x 4-inch boards, some plywood and drywall screws will make a very strong frame. Buy Projection Screen Material, Fabric for Custom Home Theater Screens. We sell projection screen material cut to your specifications. If you are building or outfitting a new projection space, then you may opt to design your own custom screen.
We offer two screen surface options and this handy calculator to compute your square footage and total cost. Select Screen Fabric Type *Please note: Projection screen fabric height cannot exceed eight (8) feet. We suggest ordering a little extra fabric to ensure a successful installation. Da-Lite's Matte White material is a versatile screen surface and a good choice when you can control ambient light. Flexible vinyl material 1.0 Gain Viewing angle +/- 50 degrees off center point, evenly distributes light over a wide area Colors remain bright and life-like, with no shifts in hue Must be stretched when installed Surface may be cleaned, is mildew resistant and flame retardant Sold by the square foot, plain cut edge, no binding Ships rolled $4.75/sq ft Projection screen material is NOT returnable.
Just Starting [Archive] - VJForums. Projector lenses [Archive] - VJForums. Throw Ratios and Viewing Distances. A projector's throw ratio is defined as the distance (D), measured from lens to screen, that a projector is placed from the screen, divided by the width (W) of the image that it will project (D/W). The ratio, like any ratio, is dimensionless. For example, if D equals 10 feet and W equals 5 feet, then 10 feet divided by 5 feet equals 2. The dimension of "feet" is thereby cancelled out. So, in knowing this formula, a projector's throw ratio will provide you with all of the information you'll need to set up a room. The following examples will better explain how this works. Example 1 Example 1: You know what screen size you want, but need to know how far back the projector will need to be placed.
If the screen width is 7 feet and the projector's throw ratio is 2.0 - 2.4:1 (because projectors have zoom lenses, they also have a range of throw ratios) then you can place your projector anywhere from 14 to 16.8 feet away from the screen. (7 * 2 and 7 * 2.4 = 14-16.8) Example 2 Viewing Distance. Strategies for 3D video with wide fields-of-view.

Implementation for Quartz Composer contributed by Matthias Oostrik: seb.zip. Includes a Core Image Filter and an example composition for a three projector display using a Matrox Triplehead2Go. Introduction There are a number of applications which benefit from high resolution displays, for example, immersive virtual reality and scientific visualisation. Unfortunately projector technology is currently limited to around the XGA (1024x768) or SXGA (1280x1024) pixel resolution and at the time of writing the later are still rather expensive. The approach that can be taken then is to use low cast commodity projectors and tile a number of them together, each driven by either a different computer or a different graphics pipe on the same computer.
Overlap Blending The resulting projected image is given below, why is there a grey band? Gamma correction R. F. Room projection using spherical mirror. Creating a wide field of view perspective projection is likely to be easier for most existing software, however when this is extended to angles greater than 100 degrees the pixel efficiency is rather poor. There are other projections in common usage in immersive environments, for example cylindrical projections and cubic maps.
Both of these can ready be warped using the same principles used above and would be significantly better than using perspective projections. The author would recommend using cubic maps, that is, multiple passes where each one captures a 90 degree FOV. The resulting views (typically 4 from left, right, top, bottom) are each applied as a textures to a textured mesh.
