Simulation using animation

i am trying to create a applet to simulate the TCP/IP
protocol suite. I want to have two computers on screen with messages going between them. One computer will send a message and the other will send an acknowledgement back, this will have a counter and if the acknowledgement is not received within a certain amount of time the message will be retransmitted. could you please give me some idea as to where to start with this. I'm assuming i use two animation loops and threads.
Many thanks
Deirdre McKenna

The simplest way would be to use one thread. In the run method update the data, increase the animation frames, then render the scene.
Is the question about how to draw animations, or the stucture?

Add 3D Modeling, Simulation, and Animation to LabView

I am posting to announce the availability of RoboWorks software.
RoboWorks is an easy to use software tool for 3D modeling, simulation
and animation of any physical system. It provides an inexpensive
alternative to hardware (especially robotic) and brings 3D simulation
to every desktop. When using RoboWorks you will benefit from:
* Extremely intuitive model development
* High quality, fully interactive 3D graphics
* Lightweight files that conserve disk space
* Full animation, even while building your model
* Interfacing with popular software packages
Most analysis and visualization software such as Matlab, MathCad, and
LabVIEW support graphics limited to charts and graphs. RoboWorks adds
3D modeling a
nd animation capabilities to these software packages. Now
you can do your analysis in the software of your choice and visualize
and animate your results in RoboWorks.
RoboWorks supports interactive animation via the keyboard (animate as
you build your model), through a data file, or through RoboTalk.
RoboTalk is an Open Source applications programming interface that
allows programs running on any platform that supports TCP/IP to
interact with and control RoboWorks models in real time. For example,
your control program running on Linux can now control your mobile robot
simulation in RoboWorks in real-time.
RoboWorks comes with full-featured help and a variety of sample models
such as those shown at left. Also included are sample RoboTalk
programs, LabVIEW support, program-interfacing support through DLL's
and RoboTalk source code for non-supported platforms.
For more information email us at [email protected] or visit

Platforms: Win 95/98/NT/2000. Any system
with TCP/IP for RoboTalk.

Before you buy.

Well, what you mention in your two sentences is somewhat of an Oxymoron. 3D modeling and animation, decent software and simple to use don't belong in the same sentence let alone paragraph. This is a FCP forum but I'll answer with my 2cents as I am a motion graphic artist that does 3D animation. There are about 6 different 3D applications that are worth their salt. Maya, 3ds Max, Softimage, Cinema 4D, Houdini and Blender. All are quite capable. None are what I would call simple to use. If you want to do 3D animation you need skills in modeling, texturing, rendering, lighting, rigging, animation, dynamics, drawing and script programming just to get started. If you are not up to spending the time and effort in having someone train to learn these skills and to spend the $$ for the hardware and software, what I would recommend is outsourcing your initial projects to get you started so you get an appreciation for what is really required to do the job and then once you understand all that is needed, you will have a better understanding of what software would fit for what you are trying to accomplish.
BTW I do freelance work.

Using Animation in your Sequence Settings ... Amazing!

Well here's the thing ....
And I'll start off by saying I have so much to learn about FCP but this has made a big difference to how my images look, especially graphics and titles.
So I'm working away at my project and the graphic images that I import into the timeline from the viewer are just ok and I'm a bit disillusioned like so many people seem to be on these forums about how the image degrades from the viewer to the canvas. And of course it is apparent later on the QT file and then the DVD that's produced at the end.
So one day, and I can't remember how it came about, I open the sequence settings and change the Compressor in QT Video Settings to Animation! Well what can I say, the image in the canvas was absolutely perfect and in some cases, it's actually a little better than how it looked in the viewer before I brought it across.
I have to produce a DVD where each week, some of the moving footage and graphic images have to be changed over. A total of about 15 minutes and all of it of course is in this Animation sequence. The downside of using Animation is
(1) the rendering time is horrendous, (or is that horrenderous?)
(2) as I'm editing, the playhead disobeys what you ask of it and you get the spinning beach ball quite often (can take 1-4 minutes before you can continue again)
(3) sometimes when you're playing through the timeline the image on the canvas and the sound quality are poor (processor running out of puff I guess)
It's a bit of a nightmare but I have no choice but to use Animation now the Marketing Department have seen the difference and expect the higher quality on the images. Cannot get this quality with any other setting I've tried in the Compressor setting. HDV1080 for instance means the rendering problem goes away but the difference in quality is obvious. The project has many different files and formats from HDV to H264s to Pro Res 422s and lots of various jpegs in various forms. But regardless of the project, I have experimented with unrelated sequences in different projects with the same result.
My questions are..... has anyone else experienced this, is there another setting that would bring about the same results and lastly, would the rendering and the other problems significantly be reduced with say the top-end iMac?
I have to tell you I almost didn't post this coz I have so little experience with FCP but it would be great to get your feedback. The weekly project I produce may take more time than it should but I have to say I'm happy with the results.
Thanks for reading.

Well... the animation codec is primarily used for sneakernetting files from one platform to another, mac to pc for example. It's a bear for a lot of computers to even play out a file without choking. The concept is make animation file, put on disk or drive, carry across the hall to the pc station, convert to something the pc station can use without choking.
I would suggest you try a little experiment: take your input material and convert it to prores (NOT HQ) before import or WHEN you import (log and transfer) and work with that natively. HDV as HDV is really a cruddy medium. Prores will give you a much better color space and have actual frames all the way through, which hdv does not. Take a one minute section of material, load on some graphics and filters etc, render it out, do your whole production process and see what it looks like. Once you move beyond the artifacts inherent in hdv and h.264 encoding you might be surprised.
Bad mistake to point out to marketing folks how cool it looks. You must be young!

Can I use animated emoticons in mail?

I want to put an animated emoticons in my signature block in emails. I can put them in my signature block but they do not animate. How to use animated emoticons in mail? If so how do I get them to work?

You said you have a url link to the animated gif.
Open that link in Safari or Firefox or some other browser so that you are actually looking at the animated gif doing its thing.
Open Mail and go to Preferences > Signatures
Select a signature to edit or create a new one.
Edit the text as desired.
To add the animated gif drag the actual image from the browser window and drop it in to place in Mail's signature composing frame. Don't worry if it only displays as a [?] icon. When you do this, you aren't actually adding the image but are creating an HTML link to the file on the internet server.
Make sure you have added the signature to the account you will be using it with. You can drag the signature name (in the middle column) and drop it on the desired account in the left hand column.
If that is the only signature you have for that account, then when you start a new message it will automatically apear in the message. If you have multiple signatures you can select the one you want (or none) from the message's toolbar.

Cartoon Solutions has this tutorial for re-using animation
for different characters. Are the plug ins for this available for
free anywhere, or is cartoonsolutions the only place that offers
it?

I think you want the "LibAppend" extension - if so - my

Re-using Animation on Multiple Characters

Hi I don't know if this is the right place to ask this, please bear with me. So in my game, I got 20 enemies that looked different, but should have the same animations. For example the dying, running, walking animations are all structured the same. But I don't want to do this manually, giving the fact that I'm using frame by frame animations, it will consume a lot of my time. Is there a way I can re-use my main animations to other movieclips/characters? Like reusing armature/animation via bone tool... thanks
There's an old thread almost the same as mine. Saw this link, and this is the one I'm talking about. But sadly, ain't free.
http://www.cartoonsolutions.com/store/catalog/Re-using-Animation-on-Multiple-Characters-Vi deo-Tutorial-p-16569.html

Yes, I'm currently using FbF. But I can't show you any SS right now for the 20 enemies, cause I ain't done with that part. I only got my player's (main character) animations. Here's some of it:
this is not drawn FbF, rather they are vector parts rotated/tweened each frame.

Using animated GIF as JButton icon

Hi,
I am trying to use an animated gif as an icon in a JButton.
Everything works as it should except the animation is static!!
Screenshots and code are at:
http://www.beammicrosystems.com/Java/JButton.html
Anyone got any good ideas?
Regards,
Andrew

well i think you can do this in a label you can watch for a animation like you want a gif so my idea is that you should just make the label as a button and them :
JLabel label = new JLabel();
label.setIcon = new ImageIcon("name.gif");
and put it the setBounds
label.setBounds(x,y,long,tall);
and if you want that looks like a button just do this
label.setBorder(BorderFactory.createRaisedBevelBorder());
thats all.

Using animated gif...

I've encountered a problem in displaying animated gif using java Swing.
For my program, I need to display 6 animated gif images. Sometimes I would get all those displayed, but sometimes only 1 or few are displayed.
This problem troubles me until I found that it is the problem of animated gif I've used, because I have tried to replace the animated gif to static ones then every time the images are all displayed.
I need a help urgently. Thanks a lot in advance.

Using animated gifs in emails

I've made an animated gif using flash an am trying to make it
so the gif appears in my signature at the bottom of every email. I
can place it in the signature but when I send the email the gif is
static and doesn't move. Also I'm using a mac and when I recieve an
animated gif in an email from a PC the gif is also static. I need
to be able to send animated gifs in emails from PC and Mac using
Mircosoft Outlook for PC and Entourage for MAC. Any help would be
much appreciated.
Cheers,

this really has nothing to do with flash at all - you have no
control over this as the recipient of
your email may not be using an email client that supports
animated gifs - does your gif work when
viewed ina web page?
you must realize there are a myriad ways people check email -
sometimes via a browser, handheld
device, email client software, etc...not all support animated
gifs and the ones that do may have
that option turned off by user.
i would consult the support section of the email software
your recipients use.

Using animation as icon for JTree node

Hi,
I am using a custom tree cell renderer. I have a label in the renderer, the label have gif Image Icon, but the problem is it is not getting animated. But when I use a JLabel with gif icon some where else it is working fine, but it is not working for tree node.

          return defaultRenderer.getTreeCellRendererComponent(tree,value,sel,expanded,leaf,row,hasFocus);
}

JLabels using ImageIcons are designed to display the icon as is, including animation and all.
A CellRenderer only paints the Icon once, when the cell is painted. Much ike a rubber stamp of the JComponent. Hence, its not designed to do the animation and all.
If you really want it, you can probably use MediaTracker and a Timer to do your animation scheduling. Might not be very pretty code though

Problems using Animation Presets from Bridge

Dear all,
Using the CC range, and recently had a new problem using the animation presets from Adobe Bridge. I'm in After Effects as normal, and then go to the Animations drop down, click browse recent presets to open up Bridge, and then as normal use Bridge to select the preset I want. Double click it whilst highlighting my selected track in AE, and then AE reports this:
And the same error codes no matter what effect/animation I choose, whether its to an image, video or text.
If I just go, in AE, to my Recent Animation Presets, and choose one from there it loads up absolutely fine. But this is massively annoying. Any ideas? This problem appeared out of nowhere.

This is fixed in the After Effects 2014.2 (13.2) update, which is now available.
