UPDATE: found Shift camera in C4D Architecture presets. It seems to solve my problem making two-point perspective renders.

I’ve had some experience in doing this with c4d. With simple setups, like this:

or even this

we had no problem.
Just had to accurately reconstruct facade by dimensions, then did animations in C4D or Houdini, and rendered using camera with FOVequal to projector’s FOV.

Than placed projector in front of facade, at known distance, and used Catalyst media server to do little corrections. Finally rendered picture fits almost perfectly to facade elements.

BUT

when it comes to complex geometry, and different projection angles, I begin to get some problems. Like this:

Picture in photo camera and render camera in C4D are different from what we actually see by our eyes in reality. In particular, vertical lines are actually vertical, and not inclined. I have tried different camera modes and parameters – no one gives right image. Whene I project this image on the surface, I gete severe discrepancy that cannot be corrected by Catalyst geometry tool.

I suppose this is somehow related to c4d vanishing point setting that is different from reality. Right now i cannot get through this problem. Would appreciate any suggestions.

Thank you, Adam! This is EXACTLY what I asked for.

I am trying to make a rear-projection screen.

There is no magic in this number, Walter.
This is maximum size of the Direct3D texture, so if player outputs using OpenGl it’s a limitation, as it treats any raster as a texture.
There’s a simple player for OSX – MSAQTPlayer, that can override this limit. But seems no one for PC.

thanks Thomas!

Sadly, but sdeCrawler is not there, when you try to dowload it:

I just found out that Mirage is now supported by TVpaint Developpement. In fact, they discontinued Mirage upgrade as they have more functional TVP Animation powered by the same technology.

Hi Andy!
Projection surface is Transscreen projection film, it’s transparent. But I also experienca this effect with regular rear-projection screens.
I advise you, next time you’ll have a projector around you, take a black reflective plate (e.g. piece of plastic, and look at the reflection. You will be surprised.

Hi Andy!
I encountered it with both LCD and DLP.
For example, in this video (see annotations): https://www.youtube.com/watch?v=jtJ842lQRs8

I mean any light color close to bright white, reflecting from black surface (plastic, dark glass, chair varnish) becomes green.
