Rotating logos
I need to find out how to make a rotating design like the one on this website: http://www.carouselindustries.com/
The logos are cycling through. I have been searching the net to try to find a tutorial on how to do this and I cant seem to find one.
Any help would be much appreciated.
Thanks,

Can you make a 3d rotating logo with illustrator to put on a website?
Hello! I need to make a rotating 3d logo for a website. Sort of like flash without flash. I tried gif builder but it didn't offer a rototing image. The logo is prettty much 3d already just need someway of getting it to rotate on a webpage. Any suggestions greatly appreciated!!!
As has already been mentioned, making the ubiquitous spinning extruded logo is considerably less tedious in other (and much cheaper) programs, like Xara 3D or Xara Designer. The lighting & shading is also better, because its output is raster.
But let's face it; spinning icons stopped being exciting about 15 years ago. It's about as stimulating these days as a slide transition in Powerpoint. There is no "wow" factor anymore. So one has to ask, what is worth the bother of doing it in Illustrator?
Three things:
First, if scaleability on the web page is required, the output frames need to be vector. (But don't go crazy with it. Instant-gratification features that try to do the illustrator's work for him [like 3D Effect] usually generate absurdly complicated constructs with far too many objects for practical vector animation.)
Second, practically speaking, Illustrator's value in this regard is limited to what must be frame-by-frame animations. For example, this simple animation is vector, and it's arguably more intersting than yet another logo spinning on its axis. But it's inadvisable for this animation to be built as frame-by-frame. There's nothing about it that requires frame-by-frame. It's just two vector paths that change over time in scale and rotation. Rotation and scale be scripted in Flash. The result is smoother and more supple animation, more efficient file size, and the real power of Flash, which is interactvity.
Example
Third, if you're going to justify the tedium of Illustrator, look for things that actually require Illustrator. For example, there's certainly nothing special about Blends. But one of the most important differentiating aspects of Blends in AI is that you can blend between live effects (and not just 3D Effect). The next example below exploits the peculiar nature of a Warp Effect's remaining oriented to the page as the object to which it is applied rotates. The example will be rasterized upon output, but the live vector Envelope and its blending expedites its creation. (The animation is on page 11 of the PDF. Allow the yellow alert to enable embedded media. Click in the middle of the page to start the SWF) :
Example.
Another Example.
Jay,
I don't know which of the above-described steps you are having trouble with. If it's the concept of using top-level Layers and removing the unwanted extra at the end of the loop, see this example:

CC Cylinder (Coca Cola effect)- Rotating logo
Hello everyone,
I am having problems trying to copy this Coca Cola effect at the end of the video.[http://www.youtube.com/watch?feature=player_embedded&v=LGh0Uuo895c | http://www.youtube.com/watch?feature=player_embedded&v=LGh0Uuo895c]
I did it with the CC Cylinder effect on the logo and use alpha matte to the bottle.
The problem appears when I do the zoom in (adding a 3d null object to the precomposition also in 3d). The image don't look sharp, but I cannot activate the Continuous Rasterization because that needs every layer to be in 3d, and then the CC CYLINDER CORRUPTS.
I would really appreciate your help.
THANK YOU VERY MUCH,

Flash 8 xml rotator.swf and main timeline frame looping
Hi Y'all -
I have a purchased swf file that randomly rotates images (90
or them) located in an external xml file. It works fine in it's own
swf file.
The author suggested dragging the movie clip to the library
and to the stage. I did that in frame one, on its own layer of my
main swf file, followed by empty keyframes for all other frames in
the main swf. That works too, only showing the rotating logos in
frame one.
However, the stop(); actions on each of the other frames are
ignored, so that going to frame two on the main timeline starts
with the proper content and then continues on to the next frame and
the next. Without the rotator, buttons control the action and I
have no problem.
This link shows the problem -
http://uniconexed.org/bigflash/unicon-05-17-08-newlook.swf
I've tried attaching the swf file and unloading it, using
"create empty movie clip" (my current attempt outlined in the
code), and about a half dozen other ways to no avail.
I think I need to kill "play movie" when someone leaves frame
one (or enters any other frame) even though not all of the 90
images have displayed. It could be some depth issue, or lock root,
I dunno.
To restate, one of two things happen -
1) the scene continues to display the files randomly over top
of the content in the other frames (wrong) but the navigation
buttons work (correct)
or
2) the random images do not display in the other frames
(correct) but the navigation stops at each frame do not work
(wrong) - the swf file scrolls through each of the frames, ignoring
the stop(); at the top of each frame.
Any help that leads to success would be greatly appreciated.
DanHi there,
Try using...
unloadClip(myContent);
instead of
unloadMovie(myContent);
unloadClip is the proper method to use when removing content
created with the MovieClipLoader class -
Flash 10.2.159 installed but doesn't play
Doing my best to provide question and system info:
Finally got Flash Player 10.2.159.1 to install. I can see the rotating logo on your "about" page. However, cannot get video to play on other sites, including AOL, where it worked before.
I am running:
HP laptop on unsecured network. 64-bit machine. 32bit IE9 version 9.0.8112.16421 which was installed two days ago (4/20) and started the problem. Have deliberately invoked IE9 from start menu to insure using 32bit version.
I have uninstalled Flash, reinstalled, rebooted, etc. multiple times. Have tried both Manager and manual install. Last was via Manager.
I have no "kill bit" entry in the registry (did not delete, it wasn't there).
I have no install error log.
Files in windows/syswow64/macromed/Flash/
Flash10p.ocx
FlashInstall.txt
FlashUtil10p_ActiveX.dll
FlashUtil10p_ActiveX.exe
IE9 Manage Addons shows Adobe Shockwave Flash Object enabled, but with blank load time.
I run Norton Utilities (v 14.5.0.120) and Norton Internet Security (v 18.5.0.125). I have had no virus/malware/etc. errors since buying machine.
Cannot find any means in these packages to check on pop-up blockers. But don't see any notices of any, either. Registry analysis under Utilities shows no errors
I turned off the hardware accelerator.
I admit to being a mainframe programmer with little knowledge of PCs but have read other posts and tried to follow instructions. So, not knowledgable but may be capable.
Wouldn't have your job for all the tea in China, but will appreciate any help or suggestions. Currently unemployed and would really rather avoid $40 fee.Oh for crying out loud.
This appears to have solved the problem. AOL videos and others now work. Thank you.
Maybe this could be added to the instructions on installation/troubleshooting? Seems much simpler than checking kill bits in the registry. -

Error while loading a swf created in flash cs4, inside a flex application
Hi there,
I have created a rotating logo in flash cs4 using motion presets, named logoRotar.swf. I have used this inside my flex application:
<mx:SWFLoader width="33.33%" height="100%" source="assets/logoRotar.swf">
When I execute the flex application, I get this runtime error message:
VerifyError: Error #1014: Class flash.geom::Matrix3D could not be found.
at global$init()
at fl.motion::AnimatorFactory3D/getNewAnimator()
at fl.motion::AnimatorFactoryBase/addTargetInfo()
at logoRotar_fla::MainTimeline()
I also tried adding import flash.geom.*; statement in my flex application, I still get the same message.
Flash player 10,0,22,87 is running in my browser.
Please help me out....
Cheers!

IPod classic won't synch...or eject
Hello all,
I think my iPod has somehow become 'unsynched' with iTunes. I noticed recently that when I connect to iTunes my iPod itself says it's synching, and I get the little rotating logo (I'm set up in iTunes to synch manually) before it settles. When I then try to synch I get a message saying '...cannot be synched. The required disk cannot be found'.
When I then try to eject, my iPod disappears from iTunes but it still says it's connected, and the icon is still on my desktop and I cannot eject it via Finder. The only way I can get rid of it from my desktop is to shut down my computer. I've already done this a few times but it hasn't cleared the problem. Is my only option now to restore my iPod to factory settings? I have just updated to the latest version of iTunes, but the problem occurred just before that anyway.
Thanks in advance.Hi,
I've since discovered that my iPod will synch / eject properly if I turn off my computer while the iPod is still connected to it. I obviously don't won't to have to keep turning my computer off and on just to update my iPod files every time, though. Can nobody really answer this? Please? :-( -
AlivePDF seems to flip image alond axis?
Hi,
In my flash file, I allow the user to rotate an image. After the image is rotated, the user can save the edited image as a PDF. I'm using AlivePDF for saves.
Here is the problem: If the user rotates in the X or Y, the pdf image looks flipped along the respective axis(for example, if I rotate in the X, the image looks like it rotated properly, but the perspective is reversed). If the rotation is in the Z, there is no issue. The event listeners are attached to slider components.
Here is an image to clarify-
My question: How can I get the image to render properly in the PDF?
Rotate Code:
//rotate logo around the X axis
logoRotX.text = "Rotate X: 0"
logoRotateX.value = 0;
logoRotateX.addEventListener(SliderEvent.CHANGE, logoRotateXPos);
function logoRotateXPos (event:SliderEvent): void
logoRotX.text = "Rotate X: " + event.target.value;
container.rotationX = event.target.value;
//rotate logo around the Y axis
logoRotY.text = "Rotate Y: 0"
logoRotateY.value = 0;
logoRotateY.addEventListener(SliderEvent.CHANGE, logoRotateYPos);
function logoRotateYPos (event:SliderEvent): void
logoRotY.text = "Rotate Y: " + event.target.value;
container.rotationY = event.target.value;
//rotate logo around the Z axis
logoRotateZ.value = 0;
logoRotateZ.addEventListener(SliderEvent.CHANGE, logoRotateZPos);
function logoRotateZPos (event:SliderEvent): void
logoRotZ.text = "Rotate Z: " + event.target.value;
container.rotationZ = event.target.value;
Save PDF code:
createPdfBTN.addEventListener(MouseEvent.CLICK, makePDF);
function makePDF(evt: MouseEvent)
var myPDF : PDF = new PDF (Orientation.PORTRAIT,Unit.INCHES, Size.LETTER);
myPDF.setDisplayMode(Display.FULL_PAGE);
myPDF.addPage();
// add a background image
var PDFsampleData: BitmapData = new BitmapData(BGContain.width, BGContain.height);
PDFsampleData.draw(BGContain);
var PDFjpg:JPGEncoder = new JPGEncoder(100);
var PDFba:ByteArray = PDFjpg.encode(PDFsampleData);
var timesbold:IFont = new CoreFont(FontFamily.TIMES_BOLD);
myPDF.addImage(BGContain);
myPDF.setFont(timesbold, 12);
myPDF.addText("Disclaimer: This image is for visualization purposes only and is not a proof.",.5,10);
// save PDF
var fileReference:FileReference = new FileReference();
var pdfByteArray = myPDF.save(Method.LOCAL);
fileReference.save(pdfByteArray, 'Your Sample.PDF');I fixed this by using ScaleX and ScaleY instead of rotateX and rotateY. Now, the PDF renders fine.

Hi. Which Directive/Class will be the better choice if your app is mainly a video camera app. I saw about 3 different Classes to capture videos. I'm currently using Microsoft.Devices/CaptureDevice to capture video. It looks limited to me because found
out I can't pause==>resume a recording. And what about Zooming? Can you tell me which way I want to go if I want to make sure my camera functionality is powerful? Which directive/class and if possible some code example on how to use it and maybe how to
zoom, focus ect. Thank you very muchI'm now using AudioVideoCaptureDevice to capture video and I can do that but the app crash when I try to set the source for the capture device in InitializeVideoRecorder(). Can you take a look and tell me what I'm doing wrong?

I have a javascript for an array of rotating logos. Each logo is associated with a link. When you click on the logo, the corporate website linked to the logo opens but it does not open in a new page. How do I get it to open in a new page?
The website link is http://lexedfoundation.org
the code calling the links is
<a href=" " onClick="clickLink(); return false;" onMouseOver="descript(); return true;" onMouseOut="window.status=' ' " target="_blank"><img src="images/corp.gif" border=0 name="corp></a>Gramps,
I'm relatively new to web development and I'm afraid I don't understand what static address I'm supposed to change. I tried substituting the http://www.externalsite.com with clickLink() but that resulted in a "page not found" message. I don't understand what "http://www.externalsite.com" represents since there is a different address for each logo. Could you please be more specific?
Thanks for your help. -
Single user mode . using tail -f (command not found)
Have an empty computer with no systems disk as the installation CD start up will not go past the grey screen with the rotating logo before the panic crash page comes up and tells me to restart the computer.
Trying to boot into single user mode and then use the command tail -f to see contents of some of the logs... BUT I get the reply tail command not found ????If the hard drive is empty, then you can only boot from the CD. Regardless of whether or not it has "tail," it won't do you any good. There are no logs.

Can anyone explain what just happened?
I was just watching a video on Youtube and then all of a sudden my entire machine freezes, and it logged out me out completely to the main login screen? There was that tiny loading rotate logo in the screen also.
What could have caused this?Hello Iftt,
Thank you for using Apple Support Communities!
It sounds like after updating to iOS 4.2.1 your phone is not picking up the cellular signal.
I would recommend the steps from this article named:
iPhone: Troubleshooting No Service
http://support.apple.com/kb/ts4429
Try turning iPhone off and then on again.
Remove the SIM card and verify that it is a valid, carrier-manufactured SIM. Also verify that it is not damaged, worn, or modified. Then reinsert it.
Check for a carrier settings update. Tap Settings > General > About while connected to a Wi-Fi network. If an update is available, a prompt should appear soon. If Wi-Fi is not available, connect your device to iTunes.
Update your iPhone to the latest version of iOS.
Restore the iPhone.
If you're still experiencing No Service issues, contact your carrier to check for any network or account issues that could cause this issue.
Regards,

How to make VideoRecorderBrush scollable?
Hi. My root layout is a Grid and I'm using a Rectangle to display the AudioVideoCaptureDevice's viewfinder. I have a option to set the capture resolution to any resolution that is available by the API. When the capture resolution is
greater that the rectangle a lot of the information of the recording (video picture) is unseen. I know I can later see it by playing it back with a fill stretch. Can you teach me how to see it while recording i.a.w make some control scrollable like
the video recorder brush? Thanks in advance:-)I followed the "how to capture videos in Windows Phone" tutorial and it used VideoCaptureDevice API from Microsoft.Devices namespace. I edited the code and where able to capture videos using AudioVideoCaptureDevice (It took me a long time to get
it right). Here is the relevant code:
XAML:
<!--LayoutRoot is the root grid where all page content is placed-->
<Grid x:Name="LayoutRoot"
Background="Transparent">
<!--Camera viewfinder >-->
<Rectangle x:Name="viewfinderRectangle" Width="auto" Height="auto" Stroke="White" Tap="ToggleZoom_Tap" StrokeThickness="5" HorizontalAlignment="Center" VerticalAlignment="Center">
<Rectangle.Fill>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="Black" Offset="0"/>
<GradientStop Color="White" Offset="1"/>
</LinearGradientBrush>
</Rectangle.Fill>
</Rectangle>
<MediaElement x:Name="VideoPlayer" AutoPlay="True" Width="800" Height="480" RenderTransformOrigin="0.72,0.479" VerticalAlignment="Center" HorizontalAlignment="Center" Stretch="None"/>

Captivate 4 bombs with 3D motion SWF
I have a small AS3 swf of a roatating logo that drives Captivate 4 crazy. I have no problem with other AS3 swfs but the rotating logo won't work. It plays fine with a Flash 10 viewer or even in the Captivate library previewer. When I try to publish or preview the slide show I get a flashing Captivate preloader and stills of the logo movie. Does Captivate 4 have an incompatibility with the 3D motion tool in Flash? It can't be duplicated in AS2.
Here's the as3 code. Think of your logo as a business card that has a font and a back. This card gets rotated on the Y axis 360 degrees. The ENTER_FRAME event is what triggers the rotation. All you need to do is create assets named mcFront and mcBack and place them on stage.
import flash.events.*
this.addEventListener(Event.ENTER_FRAME, EnteringFrame);
//Start out the rotation with edge facing you
mcFront.rotationY = -90;
mcBack.rotationY = -90;
var bol:Boolean = true;
function EnteringFrame(e:Event) {
//check boolean value
if (bol) {
mcFront.visible = true;
mcFront.rotationY += 4; //adjust this number for speed of rotation
if (mcFront.rotationY >= 90) {
mcFront.visible = false;
mcFront.rotationY = -90;
bol = false;
else {
mcBack.visible = true;
mcBack.rotationY += 4; //adjust this number for speed of rotation
if(mcBack.rotationY >= 90) {
mcBack.visible = false;
mcBack.rotationY = -90;
bol = true;
//trace("Bol: " + bol);
