[simpits-tech] Projection screens play a vital role more than you'd think... list submisson

[Rob Hommel]

Kevin:
There truly is a great deal which I omitted in my email, there are technologies and products which we haven't even discussed. The projection surface is indeed a factor which affects projection performance. Projection screens which have a capability to reflect a greater amount of light than which is reflected by a simple matte white surface is of interest to simmers. Projector screens have this ability some interesting technologies have been used by manufactures over the years. A history of these projection screens would be of interest to the sim community.(hint)

 Some home entertainment/home theater companies offer special paints to increase the projection. One item which was of interest to me recently was one manufacturer which recommend using a gray paint color. White has historically been the preferred color, I wonder if the reason white has been in use is that it is how it has always been done and no one ever questioned if indeed it was the best color.

There are any number of projection screen/projection methods we have made little mention of some examples include the fog screen. A technology which shows some interesting possibilities. (http://www.fogscreen.com/en/index.html)Then there is the  possible use of spherical domes for your sims usage there are some amusing aspects to this that I love, many of the methods employed  in this technology are utilized in planetariums. This is only a very small sampling of what is available on this technology.

Then there is the combination of hardware and software to solve a complex problem take a peek at what these folks have come up with. If anyone knows anyone at this company that can talk them into giving me one of these systems to play with please do so. I really like the possibilities.I want the software as well please somebody help me on this 
http://www.siliconoptix.com/boxProducts/ImageAnyplaceOverview.cfm having the ability to have your projector off axis and then shape the projection to the angles of the room opens so many possibilities.

There are so many possible solutions to the problems inherent to projection systems and there are quite a few that neither Kevin nor I have addressed. This is an aspect of this hobby that is frequently one that is addressed as needed instead of one which should be part of the design. Think early about your method of displaying external views instead of it being an after thought and always remember the rule of the five P's. Proper Planning Prevents Piss Poor Performance oddly enough this is an old Air Force axiom.

As always
Keep 'em Flying
