does screen goo adhere to glass? i don’t generally think of glass as a “paintable” surface, but i haven’t really tried.

i’d imagine it would work with acrylic, but glass.... ?

You can paint on glass.  Using spray paints, acrylic paints, oil based, emulsions etc.  However if the glass is not completely free of grease the paint will easily come off if scratched.  So if protected i see no reason why you couldn’t paint a screen surface onto glass

So I got some samples and I thought Id share the tiny test I did.
Tests were using the following:

Digiline Contrast
http://www.ifoha-klebefolien.com/en/special-films/projection-films/projection-film-digiline-contrast/
229,90 EUR / qm (custom pre-cut sizes upon order, max size 120x300cm)
Ships from Germany

ICE Dupix
ICE AV Technology Ltd
http://www.iceav.co.nz/product.asp?ProductID=144
Polymer foil, adhesive backing or non adhesive available.
30m x 1.6m - $US12,525
10m x 1.6m - $US5,066.00
1m x 1.6m - $US726
Thread Link: http://nuigroup.com/forums/viewreply/26121/

Both samples had adhesive backs which I stuck to my Endlighten acrylic and put my projector below it.  Below are some pictures.  My projector is very bright (2500 lum).  The discoloration seen in the Digiline in the left side of the first picture is due to air bubbles under the screen which wouldnt be there if properly applied with a spray bottle.  The Digiline Contrast is on the LEFT side of the picture and the ICE Dupix is on the RIGHT side of the picture:

Both materials did a great job.  The Digiline stuff has small particles in it that are noticeable only if you get really close to the screen, whereas the ICE Dupix stuff looked great from every angle and distance.  Both of them produced amazing images no matter what angle to the screen that I was at.  The last picture is literally my camera sitting on the screen and since it can focus really close, it recorded the different makeup of the screen material really well.  The black stuff in the Digiline stuff isnt bad from normal viewing distance and gives it almost a canvas kinda looking texture.

Parker and Peau, Could we get some samples of how well they diffuse IR light? What would be best for a DI setup? I’ve heard this is where Rosco excels, but I don’t really know.

Ive put up a summary page on my website that collects the information of mine and Parker’s tests on one page:  http://www.peauproductions.com/diff.html

As for you question Edge:
Hmm IR diffusing.  In a DI setup it is usually better to have the IR light be diffused before it hits the projection layer so that you dont have IR hotspots.  Popular ways to do this is to bounce the IR light off the bottom or sides of your enclosure.  As for the material diffusing the IR light I dont know.

Yeah my lights already diffused quite well (bouncing off the walls + some foil works great!), but don’t certain films let more IR through than others?
But anyway, I got another question, that ICE Dupix looks pretty good and since they cut it to size I might get some, do you use it on the touch sensitive side? If you do, do your hands glide easily on it?
BTW, which of the two did you end up using PP?

Edge For DI Rosco is’nt the greatest but frankly it depends on where you place rosco (i.e. above or below the acrylic/glass)… But as peau suggested you should try to diffuse IR before it hits the projection layer since rosco is meant diffusion it can do the job decently. But what i would recommend is that you use Lee Filter 273 Soft Silver Reflector to diffuse your IR, i would line the inner walls with this stuff and use it to diffuse IR light this is a hidden secret on the forums, i’ve also posted a rosco equivalent in a thread somewhere as well just search for Lee Filter to Rosco Equivalent.

I think you missed my last post, I’ve got my light diffused very well (indeed, the wall trick really is key, I found the back of aluminum foil works really well also) but I was just thinking with different films the blobs might become brighter. Since my problem is more of a hovering problem with tBeta being indecisive about certain blobs which cause’s finger id’s start climbing very fast (very noticeable while calibrating when the marker suddenly jumps several points). I figure with better contrast it might help.

I am interested in using the tinkerman method for ftir rear projection, but am unsure about about how the adhesive on the Digiline Contrast will react to the silicone or could one just leave the clear “protection film” on and apply the silicone to this.  Any ideas?  I have the funding to use a great material like this but am hoping to avoid a strange ambering down the road or some other reaction that basically nullifys the extra expense over vellum.
