Hi John,
Wow. I'm impressed. That looks pretty good - definately the best so far.
I tried to download the stage plugin - but it said something about PPC and crashed.
I think I will try to develop what you have already started. Thanks again for all your time and help.
Best Regards,
Simon Sieverts
Hi John,
thanks again for getting back.
I couldn't find the scene and stage ruby - I will also try the Fredo Scale one last time. Maybe it can be jinxed to behave appropriately.
Best Regards,
Simon
... to be more specific: Frodo can do affine transformations where parallel lines and planes are preserved, but not a trapezoidal projection from an origin which is what I need.
If I have overlooked something in Frodo which will do this, please tell me. I would be terribly grateful.
Best Regards,
Simon Sieverts
Hallo Tig,
we looked at the Fredo toolset and concluded it wasn't able to do a projectional transformation of the kind you need for an Ames room (namely a transformation with the camera point as origin and effective on every point in the room and it's contents.)
That's why I abandoned the thread and went in search for another solution - even another program where this kind of function was already implemented.
However, maybe we were wrong. Do you think Frodo could do it? I'd be very grateful if you could point me in the right direction.
Best regards,
Simon Sieverts
Hi everyone,
thanks again to Gulcan, John & Bjorn.
This may sound pedantic, but: the illusion needs to be perfect, if it be from one angle only.
The room will have objects in background, midground and foreground, so the displacement parallax needs to be held to an absolute minimum. Putting rectangular pictures or furniture in a trapezoidal room won't cut it once this is projected onto a 35ft screen. You will see the mismatch and this will take your attention away from the drama.
This sort of thing was done on Lord of the Rings and Coraline. I can seriously find nothing at all about projection transformations as plug ins for the big commercial platforms like Maya, Cinema 4D or 3D Max. I think the only way to do this is to build a plug in myself. Too bad I'm not smart enough. 
Hallo Everyone,
A lot of very smart and talented people read this forum and so I'd like to ask again for their help.
I have to build an Ames Room as a set for a feature film project.
The principles are outlines here:
http://bit.ly/ivfJUx
My problem is this: the transformation has to be done to a normal, orthagonal model AND it's contents, like furniture.
The model will be used for a blueprint for the construction of the room and all the props inside it (excluding the actors, of course).
Various suggestions have been tried out on a newbie thread here: http://bit.ly/kAsh1S Unfortunately they don't work.
Question: does anyone have any good suggestions as to where I should look for a solution? Is there a known function in any other modelling program which may prove fruitful?
Grateful for any hints,
Simon Sieverts
Hi Gulcan,
I have downloaded the file in your last post. Thanks again for your help, but unfortunately this isn't going to work. As I mentioned, the same transformation need to be done to every point in the room.
Best Regards,
Simon Sieverts
Hi Gulcan,
thanks very much for coming in and trying to find a solution.
The model from Ogan is really very good.
Have you found a way of performing this transformation to a room and all it's contents (like the furniture)? The I would have a rock-solid model on which to base the build.
Best Regards,
Simon Sieverts
PS Bjørn was right: Tgi3D has great support - even on the weekend!
Hi bjornkn,
thanks very much for your suggestion.
I have downloaded the trial version of Amorph and taken a look at the tutorial video related to locked vertices.
I cannot find a way of transforming more than one vertex at a time.
The problem is that the desired transformation effects every point of the model.
Shame that you can't lock entire surfaces.
Or have I missed something?
Cherchez la femme!
Best,
Simon
Hi Bjorkn,
which function did you use?
Best,
Simon
Hi bjornkn,
that's really good. Thanks for your suggestion.
Yes, the surfaces all need to be planar. Strangely enough all the angles seem right.
Maybe the camera should be pushed a little inside the room so we cant see the cut surfaces.

Simon

Hi John,
thanks very much for getting back.
I can see the png - it looks very promising.
Did you upload your modified file? I can't see it on your posting.
Best,
Simon

OK - here is a sample room and an adequate camera position. Let's say the person walks from the left far corner to the right far corner and apparently gets smaller...

Hallo Everyone,
I'm trying to build an Ames Room by taking an existing, normal room and applying a transformation to it.
Here's a good explanation of the problem:
http://bit.ly/ivfJUx
So basically it's a transformative projection from the camera position as origin. i.e. it is not an affine transformation.
I was looking at both the Sketchy FFD and the Control Points Plugins.
Does anyone know which which one if these plug ins, if at all, would be better?
I'm kinda a novice, so please don't assume I know too much about SU if you have a suggestion.
Thanks for reading.
Best,
Simon
PS I want to do the same translation to the romm and ALL the objects IN the room, like furniture. So ideally one would select ALL the objects and do a single (set) of translations to all of them....
