Trapcode, particular, multiple string(streamer) effects

heya,
i had posted a message late last year asking for help about creating a string type effect
see: http://www.adobeforums.com/webx/.59b7519f/5?14@@
(which graciously Aaron Cobb helped me out with!).....I wanted to create a multiple string image,
is there a way of doing, so multiple strands flow like hair in the wind, without having to make up lots of light emitters?
cheers

Well, in Particular you can get the strings to point outwards, but you won't be able to get them to behave as if wind was rushing out from the center. To get the strings to point outwards, use the "Outwards" option for the direction (this doesn't work for light emitters, FYI). Trouble is, when you do this, you will have to rely on particle velocity and not wind to extend the strings, meaning the turbulence field won't follow the motion. You can increase the turbulence field's evolution speed, but it will just make the strings jiggle, not flap as if in a breeze.
Form very likely has similar options, but I don't have any experience with it, so you'll have to do some exploration.

Creating hair/string with trapcode particular

hi
currently trying to put together a graphic which includes string gently blowing in the wind from text
i am using trapcode particular to put this together, but am open to suggestion in terms of other software.
the reasoning for using particular as i like the use of gravity and turbulence which could create an effect of string blowing in the wind..a difficulty i am having is creating a line of particles to create the string, i have tried increasing the particles per second...put the dots aren't joining up!
man i hope this makes sense to someone!

oh...have a merry christmas!

I've posted a preset at the page below:
http://homepage.mac.com/aaron.s.cobb/FileSharing1.html
It's called "Particular Streamer". I've put an expression on the Particles Per Second to make it easy to set it to multiples of the frame rate (this keeps the particles from jittering). Just put a whole number in there, and the expression will make particular spit out that many particles per frame.

How can I remove the 1 million emitter limit for trapcode particular?

Hello everyone, I've recently started playing with trapcode particular v2.2 and can't seem to rise above a problem. My PC setup is: i7 965x, gigabyte ga-ex58-ud3r, ati firegl v8600, 16 GB DDR3 2133Mhz Kingston Beast, 2x1TB WD. I want to use more than 1 million particles and the emitter does allow me to change that number. I've seen tutorials that use more than this and I can't seem to be able to use the correct settings. What must I change??? I would really appreciate your help.
Thanks!

Why use two instances of particular when I should be able to use just one?
How so? If it's not possible it must mean that the plug-in was not designed to work this way...
And I want to do that as less complicated as possible.
But then again, the opposite could be true?! Working with a gigazillion particles could be so unwieldy, it becomes effectively unworkable. Sorry, but I really don't get people's obsession of trying to do everything in one comp on one layer, when a little structured approach with pre-comping and all that stuff may provide a much simpler, more efficient workflow. E.g. in your case why would you even bother with using an emitter that has all particles, when modulating their motion to form your logo would be tricky even in a 3D program, when just the same could be achieved by multiple layers with a lot less particles?

Is there a way to create an object using Trapcode Form and then use that object as a particle in Trapcode Particular?

I made some objects in Cinema 4D and I tried to import them into After Effects CC 2014. I get an error saying 'Cannot find Adobe Premiere Pro Dynamic Link'. So I tried it in AE CC and that worked. However, I want to create a form object and then use that as a particle for Trapcode Particular. Is this even possible?
Thank you for any help!

There are also size limitations or rather suggestions for particle size. If I were creating an animated 3D shape using Form or C4D and wanted to use it as a particle I would keep the size of the particle about 1/6 to 1/8 of the comp size. You would create a new comp for your particle, animate it, then nest the particle comp in your main comp, turn off visibility, and then use it as a particle in Particular.

Using Light as Motion Path for Trapcode Particular

Hi,
I am trying to make an animation for a project, but I cannot figure out some things. I am trying to create the effect that a person is throwing money out the back of a car. I have the live shot of the person in the car, but I cannot get the money to behave how I want it to. I am trying to use the Trapcode Particular, but I can't get the particles to follow any motion path. When I set the settings to motion path, it prompts me to create a light. I create a light, but can't figure out how to make that light have an actual path rather than simply being a spot light. Please help! I'm sorry if I don't make any sense, please ask me to clarify if you need it.

Because you are doing it all wrong! If you wanted to use the Motion Path option in the Air physics model, your light would have to be exactly named like that - Motion Path 01. It's not what you want, though. I'm 100% certain of that. You are looking to create a conventional light emitter, which is a whole different thing. For that, your light should be named Emitter (or whatever other prefix you define in the plug-ins Options/ Settings panel). Then you must set the emitter type to Light. If you use spot lights and want your money to emit directionally, you need to set the emitter to Directional as well. Apart from that, Particular will use the light's color, cone angle and intensity to colorize and eject the particles. After that, you can animate the light in 3D space to whatever you need it to do.

How to efficiently log multiple data streams with TDMS

Ok, first off, I'll admit I am completely clueless when it comes to logging, TDMS in particular. That said, I'm trying to work out the best way to log some data from an existing LabVIEW-based control system, so that users can later access that data in the event of catastrophic failure or other situations where they might want to see exactly what happened during a particular run.
I've got a total of between 6 and 12 data points that need to be stored (depending on how many sensors are on the system). These are values being read from a cRIO control system. They can all be set to Single data type, if necessary - even the one Boolean value I'm tracking is already being put through the "convert to 0,1" for graph display purposes. The data is currently read at 100ms intervals for display, but I will be toying with the rate that I want to dump data to the disk - a little loss is OK, just need general trending for long term history. I need to keep file sizes manageable, but informative enough to be useful later.
So, I am looking for advice on the best way to set this up. It will need to be a file that can be concurrently be read as it is being written, when necessary - one of the reasons I am looking at TDMS in the first place (it was recommended to me previously). I also need an accurate Date/Time stamp that can be used when displaying the data graphically on a chart, so they can sync up with the external camera recordings to correlate just what happened and when.
Are there specific pitfalls I should watch for? Should I bundle all of the data points into an array for each storage tick, then decimate the array on the other end when reading? I've dug through many of the examples, even found a few covering manual timestamp writing, but is there a preferred method that keeps file size minimized (or extraction simplified)?
I definitely appreciate any help... It's easy to get overwhelmed and confused in all of the various methods I am finding for handling TDMS files, and determining which method is right for me.

I need to bump this topic again... I'll be honest, the TDMS examples and available help are completely letting me down here.
As I stated, I have up to 12 data values that I need to stream into a log file, so TDMS was suggested to me. The fact that I can concurrently read a file being written to was a prime reason I chose this format. And, "it's super easy" as I was told...
Here's the problem. I have multiple data streams. Streams that are not waveform data, but actual realtime data feedback from a control system, that is being read from a cRIO control system into a host computer (which is where I want to log the data). I also need to log an accurate timestamp with this data. This data will be streamed to a log file in a loop that consistently writes a data set every 200ms (that may change, not exactly sure on the timing yet).
Every worthwhile example that I've found has assumed I'm just logging a single waveform, and the data formatting is totally different from what I need. I've been flailing around with the code, trying to find a correct structure to write my data (put it all in an array, write individual points, etc) and it is, quite honestly, giving me a headache. And finding the correct way for applying the correct timestamp (accurate data and time the data was collected) is so uncharacteristically obtuse and hard to track down... This isn't even counting how to read the data back out of the file to display for later evaluation and/or troubleshooting... Augh!
It's very disheartening when a colleague can throw everthing I'm trying to do together in 12 minutes in the very limited SCADA user interface program he uses to monitor his PLCs... Yet LabVIEW, the superior program I always brag about, is slowly driving me insane trying to do what seems like a relatively simple task like logging...
So, does anyone have any actual useful examples of logging multiple DIFFERENT data points (not waveforms) and timestamps into a TDMS file? Or real suggestions for how to accomplish it, other than "go look at the examples" which I have done (and redone). Unless, of course, you have an actual relevant example that won't bring up more questions than it answers for me, in which case I say "bring it on!"
Thanks for any help... My poor overworked brain will be eternally grateful.

Light Streaks - Not Using Trapcode particular

Hi there i am here to as a question .... is it possible to create Light Streaks whiout using the Trapcode Particular from Red Giant ??
Regards ASilva

Well on Programs like blender i don't know how to works with them
And besides i was just asking if it was possible to create something similar to the effect i show on the link or the same without the need to use the Plugin Trapcode.
Or if i can use the particular Pluging that is already on After effects like the "CC particle world" ... (guess that is the correct name).
And if it is possible i would like to know because buying the plguin would be too expensive for my pocket

Multiple Audio Streams?

I'm wondering if there is an application that will allow the computer to route multiple audio streams out of my Mac Pro. or- if anyone knows how to create an easily switchable audio routing panel rather than going through preferences.
Eg. I'm playing Itunes (or hulu or netflix) through my audio line out through my Samsung TV thorough a speaker system to watch online content through the TV and I want to work on files on the computer at the same time, say edit video using FCP and routing that audio through USB speakers at the desk.
Being able to create multiple audio stream routing would be a HUGE asset for someone like me. Even if it's not possible, I would certainly love it if Apple would incorporate a quick switch selector in the pulldown menu for audio volume...
Thoughts? Anyone?
Thanks!

Thanks, the "auxillary effect" totally helped me stream itunes music to my iSight with soundflower....giving webcam streaming my system audio, which I couldnt do before without hearing anything....ugh so complicated! but this works!! Sometimes apple is so rediculous and I know there are more features they could build in.
Thanks!

How can I send multiple string commands into a VISA write?

Hi Fellow LabVIEW users
I am very new to LabVIEW (2.5 months) so please forgive me if my lingo is not up to par.
How can I send multiple string commands to a VISA write. For example each string command looks like this
1) 3A00 0000 0000 FFFF FFFF FFFF 0000 0000 FF00 0000 0000 0000 0000 0033 (Scenario 1)
2) 3A01 0000 0000 FFFF FFFF FFFF 0000 0000 FF00 0000 0000 0000 0000 0034 (Scenario 2)
3) 3A01 0000 0000 33FF FFFF FFFF 0000 0000 FF00 0000 0000 0000 0000 0067 (Scenario 3).
and so on and so forth. And there are a number of scenarios.
Each String scenario will give a different string output which will be interpreted differently in the front panel.
Right now I have to manually change the string commands on the front panel to give me the desired output. How can I do this without manually changing the commands i.e. hard coding each scenario into the block diagram?
Thanks, any feedback will help.

How do I input multiple string constants into VISA Write

I am trying to put in multiple string commands into VISA Write to control a motor arm. However, when I use "concatenate strings" to link together my multiple string constants, only the first command is executed, and neglects the other commands below it. Should I be using something other then "concatenate strings" or do I need to use a delay so that the next command executes when the one before it is finished? Help.

Concatenate strings should work or just use one string constant with multiple lines. The problem you're having could be that the instrument requires some sort of delay but without details on the instrument, only you or the vendor can answer that. Some instruments will have a queue and others won't. The other possiblity is that you need some kind of termination character between commands. This might be a carriage return for a serial instrument or the ; character for a GPIB one. Check the instrument manual or provide the make and model and maybe someone here has some experience with it.

Finding multiple strings in a text file and deleting the entire line

Get-Content c:\output-Copy.txt | Where-Object {$_ -notmatch 'something1', 'something2', 'something3', 'something4' } | Set-Content temp.txt
Above is the program that when it has 1 argument in the -notmatch part will find the specific string and delete the entire line. I need to be able to use multiple strings for my search, I am totally drawing a blank on this and I know its something REALLY
simple but my brain is fried. The above code will work IF i only leave 'something1' and delete the rest. I need to find MULTIPLE matches and remove them all at once, what is a good way to accomplish this.

You can use an alternating regex, like this:
Get-Content c:\output-Copy.txt |
Where-Object {$_ -notmatch 'something1|something2|something3|something4' } |
Set-Content temp.txt
[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

Home Theater need. Multiple Audio Streams from 1 card or possible to use 2 car

I currently have 2 SB Li've's installed and a SB Audigy in the box.
I would like to be able to send different audio out to different devices. I need to send audio from a game interface called MAME 32 to a speaker system connected to the PC. I also use this PC as a home theater PC and want to send audio from my DVD playing software out to my TV(in analog stereo mode) and/or to my receiver(in Dolby Digital mode using the digital connector).
I would like to be able to run these seperatly without having to go into the Control Panel and switch the default sound card like I am doing now. I do not need to run them at the same time.

Bummer. Are you guys working on something that might have this capability? Seems to me that the closer we integrate PC's into our entertainment systems the more need we will have for the ability to do multiple audio streams, i.e. MP3's to the living room. DVD movie audio to the family room, XM radio classical station to the kitchen for mom etc..
Intel is offering this as an onboard solution that has the ability to do at least 2 different streams.

Multiple Forecast Streams in Demantra

Hey,
I've noticed release note for 7.2 includes the following enhancement:
"You may want to create statistical forecasts from multiple demand streams.
You can generate a forecast from any data stream, for example, booking history and shipment history. Each data stream has a unique engine profile and version."
I haven't been able to find much documentation about this option.
Has anyone implemented a solution using that ? Know any HOW-TO documents available?
I'm thinking of using it for forecasting - item sales, and item returns from customers.
How should SALES_DATA be loaded for that scenario? How should engine be run?
Thanks alot for any reply,
Aaron

Hi All,
Forecasting with multiple demand stream means that you can generate multiple forecasts based on different demand stream. By demand stream, i mean the historical data stream on which you want to generate the forecast.
There can be situations where you may require to generate forecast for different purpose.Like Aaron mentioned, you may want to generate a forecast based on the order/booking history and/or you may want to generate a forecast based on the returns history. For this purpose you need to create different engine profiles.Engine profile is nothing but a set of engine parameters with specific values. Oracle Demantra provides some predefined profiles for different purposes, and you can define additional engine profiles, as needed. When you run the Analytical Engine, you specify the engine profile to use.
Now coming to the HOW-TO part:
1) The quantity_form (system parameter) contains an expression that is used by the engine to retrieve and aggregate demand stream data from the SALES_DATA table. Make sure that the quantity_form expression for a specific engine profile points to database columns containing the historical demand stream desired for the profile. Meaning, if you want to generate a forecast based on booking history then the quantity_form should point to the booking history stream in the sales_data table. Likewise for returns history, point the quantity_form to returns history stream in sales_data table.
2) Create a series to view the forecast generated by the engine profile.
3) The newly created engine profiles gets added to the list of engine profiles in the system parameters.You can select the required engine profile and generate the forecast.
4) View, Edit or compare the forecast created in step 4 by creating a worksheet with all the forecast generated.
I hope this brings more clarity to the queries/replies posted earlier.
Regards,
Shekhar

Multiple input stream in one socket connection

Can we have multiple input streams for a java socket connection? It means that in a client/server application (creates using java socket), can we have multiple input streams for the client side program. For example, the input streams are to cater for the need of letting the user to chat and downloading some files from the chat partner at the same time. And do we need to use thread to create the multiple input streams like the case when we create a multithreaded server? Anyone out there who knows the solution please post it. Thanks in advance.

a Socket can have only one InputStream (Socket.getInputStream()) and one OutputStream Socket.getOutputStream()). So you will have to create a way to make multiple Socket connections in your client program. And yes, you have to use threads for your server. if you dont the client will have to wait until the user before them is finished with the connection before being able to connect. I hope this helps you out. BTW please check out http://www.javabible.com. they have the book online now for free.
