Is there a ruby API for plugins to access the camera information?
Pleas read the API docs [although be warned Google can't be bothered to have someone appointed to correct or update these on a regular basis - although they can always have their 'thought-police' lurking around...]

@TIG: That assumes that the cameras in ACT use only the existing ruby classes. Is that the case, or did they create new classes with extended functionality?

(I'm very familiar with the API docs )I never said that it only used the current classes - I was comparing/contrasting it with the original version - re-read the post to see that...
Considering the 'Google thought police' are now out and about, I must say 'NO' to your query...
As far as I know, there are no new methods added by this tool [new methods from Google that might prove useful to the wider community might be too much to ask for
] - a simple '.methods' check will confirm this... -
TIG,
I apologize if my previous message was not clear enough on this point, but I never intended to criticize or chastise you or anyone else, nor did I ever use the word you in any of my statements where Google's terms were quoted. I am very careful about the words I choose and I meant them exactly the way they were written. Although my post addressed quotations from your message, the heart of the content was meant as a general notice to clarify the issues for everyone (as I explicitly stated). Please understand that there is no hidden agenda or meaning intended beyond just trying to help make sure everyone understands the issues. Doesn't it seem appropriate to you that I should respond to these sorts of comments immediately upon their first mention instead of waiting until potentially several people started trying or discussing the use of subversive techniques to do so? I think that's the point at which it does the most good, anyway.

I still fail to see why this current Plugin ended up being 'Pro only'.
As I mentioned in my first post to this thread:
@andrews said:
The plugin only works with the Pro product, not the Free one, because these tools are aimed at film and stage professionals, not everyday modelers. I personally believe that the argument to use SketchUp for film and stage work is greatly strengthened by access to LayOut, which only comes with the Pro product. I think it's in everyone's best interest if we ensure that folks who use SketchUp for film and stage work have access to the full suite of professional tools offered by Google SketchUp Pro.
Although I was an outspoken advocate for making this a Pro-only feature, it wasn't my decision that made it so. Whether anyone agrees with the decision or not, I can assure you that it was carefully considered by all of the right parties on the SketchUp team before the decision was made.
@tig said:
The previous 'version' of the very similar tool was never limited in this way...
I realize the previous version of the tool was not encrypted, making it more available for people to use on several platforms. However, I contend that the old "Film and Stage" plugin was "Pro only", as it was written in 2005 before there was a free product at all and was never repackaged for use in SU6 or SU7. This is the first opportunity we had since creating the free version of SketchUp to explicitly decide whether these tools should run on Pro, Free, or both.
@tig said:
There are many 'ordinary' people who have undoubtedly assisted Google in the testing of this tool and may now find themselves unable to use it [if they are not Pro users] without any prior warning that this might be the case when it was finally released...
I recognize that over the past few years, many folks have found workarounds to get the old F&S plugin installed and working with free versions of SU6 and SU7 and that some of those people probably provided feedback to us that was useful in the creation of the ACT. It is unfortunate that these users will not have access to the ACT plugin in the free product, but that's just the way it is. I am sorry that no warning was given, but I honestly don't see why one should have been expected.
@tig said:
I do/did not 'encourage' anyone to break the terms of any agreements
Agreed--I never said that you did. Again, my comments were meant to be read and understood by anyone who comes across these forums.
@tig said:
I suggested that any attempts to do so might well be regarded as being 'wrong'...
Agreed. You said:
@tig said:
but then you might have invalidated the user agreement
...which is precisely why I followed up by citing specific sections in the EULA that describe exactly why your assessment seems correct. If it hadn't been for you mentioning the user agreement, I probably wouldn't have thought to go into the details at all.
@tig said:
My comment about an 'empty registry entry' ... wasn't "recommended"
As I've already stated, I never claimed that you made any recommendations.
@tig said:
if that simple ploy compromises your tool then may I suggest that a more robust method should have been considered...Did they not think of that simple ploy to circumvent checking ? I hope they did ! You could have asked many users, like myself who might have had some advice...
I never addressed anything regarding the level of difficulty required to circumvent the security that is in place. We certainly have thought of many ways that a person might attempt to compromise the product and we employ a number of different strategies to defend against such attempts. We know our security isn't perfect, but that's not the point. The point is that I simply explained for the benefit of everyone, that it's probably not a good idea to subvert, or encourage anyone else to subvert, the protections that are in place, because to do so would be a violation of the EULA.
@tig said:
Also do you really suppose [as you have 'hinted'] that if I were able to 'crack' Google's encrypted rbs files I would publicize that fact ... please reread my post to see that I do not say this at all
Again (feeling like a broken record), there's no subtext in my original message; I never hinted you would attempt to crack an rbs file. I believe you're taking all of this way too personally. I don't need to re-read your post because I read it carefully in the first place (as I wish you had done with mine). I think if you were to take a step back and consider the intent of my post from an outside perspective, you would find that it really is as simple, straightforward, and un-targeted as I claim it to be.
Thanks for your understanding,
Andrew

"Have a nice day."
Intended in the most insincere form of that vapid American phrase...
Considering most Americans' lack of the understanding of 'irony' you have managed to wrap up an impolite personal insult in your anodyne niceties, intentionally or not...
My 'comments' weren't initially aimed at you personally, but at Google generally.
Somehow you have construed them to be aimed at you personally, I don't care one jot about you ! [sorry - but it's a fact]
My points all stand, without retraction.
Here I stand, I can do no other.

TIG, lets take it back down a notch, goodness. And I didn't appreciate your off-base anti-American stereotyping.

I apologize for any offense to you or your countrymen - but there has also been some 'acrimonious' PMing in the background... So AndrewS's closing '...Thanks for your understanding...' was, to an Englishman, 'a sarcasm too far'...I shall take no more part in this thread.
I am even actively reconsidering my broader relationship with Google in the light of all of this
-
Chris... you know the world hates us... with what they're shown on TV how can they not?
and you know the Brits have a much different idea of interpersonal relationships than we do. they take offense to some of the ways we interact with one another. politeness is an art-form over there, they find us quite abrupt and assumptive... we may all speak English, but that doesn't mean we're that similar...
I think we can all agree that we each have a great amount of respect for the Google team and all of the plugin developers here in SCF...

Andrew... Dude... don't piss Tig off, we need him much more than we need you...
Don't worry Andrew, we love you and your team too.

FYI - I've done some camera tests to compare how SU's ACT frames up with a real world camera (RED One), and I met with the plugin's programmer. I've found that it's off by a little bit by default and you can get it a tad more accurate (accurate enough for shot planning in the real world) if you adjust the camera to how real world cameras calculate their focal length.
I'll post some results as soon as I'm back on my regular computer (and not on my iPad). But in short - the camera is off by the focal length of the lens you're using. So if you are using an 85mm lens, you should move the camera closer to your subject (at the axis of your camera) by 85mm. That will make your framing accurate to real world cameras.
Also, keep in mind if you are using older files with the new ACT, you should redo all your cameras. Old SU files with the old Film and Stage cameras don't work well with the new plugin. Even the Beta version of Film and Tools. So if you're on a project with using the old F&S, and don't want to go through the pain of recreating your cameras, as well as don't need the accuracy, I wouldn't upgrade to the new ACT just yet.I've been eagerly waiting this update and I'm pretty darn happy with the results. It's enough baseline work to get someone who would really want to create some cool camera plugins to make SU a precise addition to a cinematographers workflow - which is what I do.
If you have any questions just PM me.

I've been playing with the new tools(they're nifty, thanks!) - what would make them more useful is if 2D export would clip away the area of the image covered by the aspect ratio masking bars. This way if I need to match an existing image, I don't need to re-size my SU window, or crop the image in an external program.
Is this possible?

Just wanted to comment on Monsterzero's comment about camera positioning.
If you are trying to accurately represent a real world camera (as most ACT users are) you have to understand how the ACT represents the camera and how real world cameras work. The thing to make clear is that the ACT camera is positioned at the focal point and not the film plane of the camera. Unfortunately the focal point of a camera moves as the focal length changes. So as monsterzero points out, if you want to position a camera's film plane 5 meters away from a target and you are using an 85 mm lens then you would move the origin (5m - 85mm) = 4.915m away from the target. This difference in positioning can make a big difference with "long" lenses (i.e. large focal lengths) and when you are very close to your target.
For those out there curious about how ACT works in more detail read on. All of ACT was built using the existing ruby API with no modifications or additions. That is why it works like any other plugin without an update to SketchUp. You only need 3 numbers to specify a real world camera. The image width (this is the actual film or sensor width), the aspect ratio of the film or sensor (w/h), and the focal length of the lens (in mm). These can be set on a SketchUp camera through the ruby api. Thats it. When you set a non 0 aspect ratio to a camera in SketchUp it shows the masking bars on the screen to maintain the correct aspect ratio. Also when these are set the horizontal and vertical field of view stays constant unless you change the focal length.
One of the trickiest parts of writing the plugin was acquiring all of the camera data. Getting accurate data from the web can be difficult so most of the best data was requested directly from the camera manufacturers.

I for one support ACT being only for the Pro version. The way I see it, the more folks who are serious enough about SU to actually want ACT who PAY for the software, (presumably) the more money will be spent developing SU.
I'm a good example of this as I've never bothered to upgrade to SU 8 because it had nothing I was interested in. Now this relatively minor plugin will probably get me to finally walk down to I.T. and have them shell out the $100.

Right now the only way to do it on a mac (without resizing the window) is to unlink the chain locking the size of the export and then inputting the size you want with the pre-calculated width and height to your desired aspect ratio.
And thanks for the info BBrown!!

What?! I wanna chain!
I'm guessing that's a mac-only feature?

I'm also very much in favor of this and most new tools being Pro only as the gap between Pro and Free version is not large enough IMO... I'm perfectly willing to support Sketchup financially and will continue to do so, hopefully tools like this will convince others that it is in their interests to do likewise.
BTW, I love Layout and certainly see it as a software that can develop into a legitimate application worthy of the license fee by itself over the next few versions... but for now it is nice to see the Pro users getting some much needed love from the Google Dev team.
Best,
Jason. -
when i set up an advanced camera all my views get clipped and i can't see nearly half of my image...
is there a way to disable or adust the clipping? where is it set? it is not displayed in the advanced camera settings?!? -
Hi Numerobis,
