  • Q How to build a professional projection system for 3D mappings?

    A It goes without saying that there’s a significant difference between projecting a 2D image onto a flat and uniform screen and projecting onto medieval façades or industrial constructions. 3D imaging naturally adds some extra challenges to projection. The surfaces of 3D objects can vary in form, color, structure, etc. It’s important to keep these things in mind throughout the process to make sure your projection mapping is eye-catching.
     
    1. Choosing the right projector for 3D mappings
    3D imaging naturally adds some extra challenges to the projection. The surfaces of 3D objects can vary in form, color, structure, etc. It’s important to keep these things in mind throughout the process to make sure your projection mapping is eye-catching.

    2.what elements you need to consider before building a projection mapping system,
    which specs you must look at when choosing a projector – from brightness levels to resolution, and other projector design requirements to make your project successful.

    3.Barco solutions
    Let your creativity run free with visualization and processing equipment that excels in flexibility.Projection
    Our video projectors come in a wide range of brightness and resolutions. Thanks to their incredible color accuracy they are able to cover varying surfaces, from red bricks to shiny metallics. And their rugged design is the ideal solution for outdoor mappings.
     
    4.Image processing
    Our presentation switchers are the most advanced video processing and presentation control systems on the market today. They enable the perfect mix of virtual images with the physical world with zero-stress image blending and warping.
  • Q Why projection mapping?

    A Projection mapping is a visual feast, a new kind of fireworks, an extraordinary form of entertainment with an enormous wow factor. It gives you the unique opportunity to attract and immerse large crowds with captivating shows and inspiring spectacles - even from a distance (which is not unimportant in times of social distancing and gathering restrictions).
  • Q What is projection mapping?

    A Projection mapping is a 3D video projection technique using light and colors to project virtual images on irregular shapes and non-flat surfaces like industrial sites, public buildings, city landmarks... Everything is a blank canvas. With projection mapping you can make anything completely change color, texture and shape.
    On the streets or inside, for big or small projects, permanent setups or temporary events…
    Bring your story to life with projected images in the most dynamic way and create memorable experiences.
     
  • Q Can I use a sheet for a projector screen?

    A

    While you will get a visible image, a sheet is not a great projection surface as it lets so much of the light straight through it. It’s also difficult to get the material nice and flat, so chances are you are going to end up with a washed out, wavy looking image.

  • Q Can I make my own projector screen?

    A

    Yes you can, but it can be tricky! It’s possible to purchase screen fabric so that you can make your own projection screen, the difficult part is ensuring that you get a nice flat projection surface to work with. If the screen material isn't pulled taut evenly from all angles, you’ll find you get waves in the projection that make for a bad viewing experience! If you need a screen made to custom requirements, please get in touch with us and we can get a quote for a custom made screen - it’s best to leave these things to the experts!

  • Q What is a Ceiling recessed screen?

    A

    A ceiling recessed screen allows you to hide your screen away in your ceiling, meaning it’s completely out of view when the screen is not in use. With many of the same features as an electric screen, a ceiling recessed screen is typically found in a high end home cinema or conference room.<o:p>

  • Q What is ALR projector screen?

    A

    Ambient light rejecting is the ultimate in screen technology. It cleverly rejects ambient light from around your projection area, think lamps, sunlight or ceiling lights and focusses the projected image. It’s essentially being selective about what you should see and what you shouldn't. ALR screens can be used to enhance black levels and the overall quality of your projected image, you may see them called ‘high contrast screens’ and you will find certain fabrics designed for darker environments and some that excel in brighter rooms. A good ALR screen can make an old projector look like new again! 

  • Q Custom made projector screens

    A

    If you have a special requirement for a projector screen we have the possibility to manufacture a screen specifically to your requirements. Custom frame screens and custom electric screens are available, just let us know your screen size requirements, what type of fabric is needed and the delivery address, and we’ll get back to you with a price!<o:p>

  • Q How far back can the projector be from the screen?

    A

    This really depends on your projector and its throw ratio. The throw ratio can seem confusing when you look at the numbers, but it’s just telling you how far away the projector needs to be to produce the image size you require. A throw ratio of 2.00:1 for example means that the projector will be 2m away for a 1m wide image - it’s as easy as that! Most projectors have some zoom, so you will usually see a smaller number and a larger number, for example 2 - 2.5:1. Here, the 2 refers to the closest distance the projector can be and 2.5 refers to the largest distance it can be, so for a 1m wide image the projector has to be 2 to 2.5m away, while for a 2m wide image it needs to be 4 to 5m away. Don’t forget to check out our projection distance calculator if you aren't sure.<o:p>

  • Q Which aspect ratio is best?

    A

    This really depends on what you are using your projector for! 16:9 is the go to for entertainment, think movies, gaming, sports and TV. 16:10 is the modern business format, so if you are working from a laptop, perhaps giving presentations, web browsing or video editing, 16:10 is the way to go. 4:3 is becoming less and less common, it's an outdated format which is not found in modern technology, that said, it is still used and is often found in churches and educational settings. It’s important to match the screen you purchase to the aspect ratio of your projector, otherwise you will end up with a lot of screen area you can not make use of. Take a look at the graphic below to see how the incorrect format will look on your screen.
