Pixel Bender Filters

I`ve just downloaded the Pixel Bender filters for Photoshop CS4 from Adobe Labs. The speed of those filters is really incredible (GPU accelerated)!
But the filters itself :(
Most of them are pretty much useless in my opinion. I hope we will get more usefull filters like a simple gaussian blur or unsharp mask or smart sharpen. Of course we already have those filters in Photoshop, but not at that speed. Pixel Bender is really realtime!

Thanks, Stephan,
I wonder how much onboard memory new cards need to handle 8000x8000. It looks like the Technote on GPUs and OpenGL has been revised. I don't see the information that I recall earlier about what features work with various amounts of onboard GPU memory. There are more specifics in the FAQ at the bottom of the technote:
http://kb.adobe.com/selfservice/viewContent.do?externalId=kb404898
These are the FAQ's that seem most relevant to spec'ing a card:
>>
Q. How much video RAM can Photoshop take advantage of?
A. Photoshop is limited by OpenGL itself on the amount of video RAM it can access. Photoshop can access approximately 500-700 MB of video RAM. 3D, a separate feature from OpenGL, allocates its own GPU resources, and can use as much video RAM as is on the display card. If you load a large 3D volumeric texture, for example, it might use a considerable amount of RAM (such as 1 GB) by itself, leaving less than expected for the rest of Photoshop.
<<
So if I'm working with a 3D layer in PS CS4 extended, it sounds like 1.7GB of memory would cover Photoshop's maximum memory utilization and the adapter's 3D rendering overhead.
>>
Q. How much RAM do I need on my display card to run faster in Photoshop CS4?
A. For basic OpenGL functionality, you should have at least 128 MB of RAM on your display card. If you're running Windows XP in general, OpenGL will work best if you have 256 MB RAM on your display card. Most Photoshop work will run faster with between 256 - 512 MB of display RAM. If you do a lot of 3D work, you use Panoramas or large images, or you need to have multiple applications open at the same time that use the GPU, you might benefit by having 512 MB or more RAM on the display card.
<<
As I recall, the earlier version of this technote spelled out in more detail what "basic" OpenGL functionality means one image window without too much resolution in my experience.
The specific mention of XP suggests it needs more memory for OpenGL functionality. Vista virtualizes the graphics adapter and XP doesn't. I've yet to see anything but vague "it works better on Vista" from Adobe tech on what the GPU performance difference is between the two platforms.
>>
Q. Does Photoshop take advantage of dual-GPU display cards?
A. Not at this time.
<<
SLI and Crossfire aren't utilized by Photoshop.
I guess I'll stand pat with the GTX 280 card. I wonder if running Aero features uses GPU memory.

Pixel bender filters in Photoshop Panel

Hello,
I'm writing a suite of Photoshop filters with PixelBender and would like to know if there is a way to call them from a Photoshop Panel built with Configurator without embedding these filters in a flash panel.
I tried to build a panel with configurator, but in the filters menu, PIXEL BENDER doesn't show. So, I guess I will have to build a flash panel which is close to Chinese for me (read http://forums.adobe.com/message/37408).
Am I out of luck?
Thanks!
Enrique

Use a 'Run JavaScript' button from ACTIONS/SCRIPTS section of Configurator.
Then use/modify the following code:
try{
var idPbPl = charIDToTypeID( "PbPl" );
    var desc636 = new ActionDescriptor();
    var idKnNm = charIDToTypeID( "KnNm" );
    desc636.putString( idKnNm, "Kaleidoscope" ); /*modify the name of your pixel bender filter*/
    var idGpuY = charIDToTypeID( "GpuY" );
    desc636.putBoolean( idGpuY, true );
    var idFPth = charIDToTypeID( "FPth" );
    desc636.putString( idFPth, "/Applications/Adobe Photoshop CS4/Pixel Bender Files/kaleidoscope.pbk" ) /*modify the path to your filter*/
executeAction( idPbPl, desc636, DialogModes.ALL );
}catch(e){
     /* catch user cancellations */
I have it so the default settings are populated and the Pixel Bender dialog is shown (DialogModes.ALL). You could use the scripting listener plug-in to populate specific settings and/or not show the dialog (DialogModes.NO)

Applying Pixel Bender Filters to MediaElements

Hi,
I want to apply a Pixel Bender Filter to an ImageElement. In general I do this like:
var shader:Shader = new Shader(new PBFilter() as ByteArray);
var filter:ShaderFilter = new ShaderFilter(shader);
var image:Image = imageElement as Image;
image.filters = [filter];
Now ImageElement doesn't support the .filters parameter. Are there any plans for this function in a future release of OSMF? Or are there different ways to apply a Pixel Bender filter? Thanks

If you're working with the MediaPlayer, then you can assign the filter to the MediaPlayer's displayObject property once the image is loaded:
mediaPlayer.addEventListener(MediaPlayerStateChangeEvent.MEDIA_PLAYER_STATE_CHANGE, onStateChange);
mediaPlayer.media = imageElement;
function onStateChange(event:MediaPlayerStateChangeEvent):void
if (event.state == MediaPlayerState.READY)
mediaPlayer.displayObject.filters = [filter];
If you're working with the ImageElement directly (and no MediaPlayer), then you would need to access the element's DisplayObjectTrait, which holds the DisplayObject.

Images don't show in Pixel Bender Filters.

Just downloaded and installed Pixel Filters into PS5.. No problem doing that or finding the filters within PS, but when I go to use the filters, the image doesn't show. I'm working on a duplicate of the image, I've turned the GPU down to basic (because I got a warning), but when I try to use a filter . . . nothing. Any ideas?
Running PS5 Extended, version 12.1x32 on Windows 7. I have a Radeon HD 4500 series graphics card.
Thanks.

I've got a similar problem. I am VERY frustrated, as I use Oilpaint for my work. I have posted on several Forumsstarting 4 months ago, talked to Adobe (who gives no support for this) and have had no help.
I have been through 5 computers, my 6th is on the way .... several cameras and memory cards. Only one out of 5 computers has no iisue (my wife's). The problem seemed to be gone, when I bought my 5th computer .... then I bought another camera - now it's back!!! So, my conclusion is, that this issue has something to do with how information is writtrn onto a memory card. Maybe some computers "pick up" on some little thing and get confused - I don't know. Again, only my laptop works fine, even with thge new camera.
Try what I did, use another computer - until you find one that works ... friends, family...etc. Also, I just found out, that the only way to make Pixelbender work when it does not, is to turn off GPU ... although that slows the process down a lot.
If my new laptop does not work with my new camera, I'll get another camera and try again .....

Looking for filters for Pixel Bender CS4 32 bit OS

I just downloaded and installed Pixel Bender as I am hoping to get something similar to 'oil painting".
Looking for filters for Pixel Bender for:
CS4 32 bit OS.
Is there any out there?

I don't think you'll find an oil paint filter for photoshop cs4, since it wasn't until photoshop cs5 and pixel bender that had the oil paint filer and as far as i know, adobe
has never made the oil paint code public.
There used to be lots of pixel bender filters for photoshop cs4 on the adobe exchange, but adobe shut it down.

Pixel Bender Gallery Error in Photoshop CS4 Student Edition

When trying to access pixel bender filters with Photoshop CS4, filters>Pixel Bender>Pixel Bender Gallery, I get an Error dialog images as follows...
I have read the ReadMe file and have the GeForce 8500 GT Video Card on this list.
The Pixel Bender Toolkit is installed at C:\Program Files\Adobe\Adobe Utilities\Pixel Bender Toolkit c/w pbk filters that run in the toolkit.
In Photoshop there are a number of pbk filters in C:\Program Files\Adobe\Adobe Photoshop CS4\Pixel Bender Files.
The Operating system for the computer is Windows XP Professional c/w service pack 2 at least.
My question is... why am I getting this error message and how can It be fixed?

Here are two further images and an NVIDIA System Information report you asked for that I have prepared, I hope this will help.
I am aware that I could download trial versions of Photoshop CS5 and its Pixel plugin version, but first, this first image shows a message that loads from Photoshop CS4 when I start the program and has always done so from day one of owning the machine and the software, could this be of relevence to what could be the root of the issue at hand.
I also use 3D Studio Max with OpenGL and have noted rotating moving objects in 3D space of a file size of 10MB is very slow and chuggie, is this relevent, does this information give any clues.
Thankyou again for your time and effort in helping me resolve Pixel Bender Gallery Error issue.

Pixel bender wont open on win 7

i have been tryign to install pixel bender toolkit 2.5 so i can pplay with the droste filter that was not added to creative cloud a bit disapointed its nto in the new creative suite thta i pay for but that sneither here nor there the pixelbender program shoudl run as a standalone program from what i have found. now problem i have is that when i open pixel bender it closes right away nothng happens liek error messages it is liek soemone clicked close as soona s it opened. please help me as i havebeen pulling out my hair tryign to fix i even reintalled windows and problem is still here. the program will work if i downlaod the old 1.5 version but i dodnt see why the new version wotn open. pleas ehelp

I've got the exact same problem:
Trying to open the Pixel Bender Toolkit, it immediately closes after initiation. No message whatsoever.
I hadn't used the plug-in for a while, I have changed my graphic card to an unsupported NVidia card. But the Pixel Bender filters do open in Photoshop CS5(12.0 64-bit), although new filter don't seem to show up (but that might be a different issue)

Problem with Pixel Bender

Hi - I am 85 years old and not very experienced with computer jargon etc. My problems with Pixel Benders only started after I recently had my Dell 64 bit computer upgraded. Previously it used Windows XP and had 4 gigs of RAM my graphics card had only 64 MB. HOWEVER, before the upgrade Pixel Bender filters worked perfectly, I have a folder in "My Pictures" that contains 65 images that have all been treated with a variety of P B filters, I am very pleased with the results. My software includes Photoshop CS5 also Lightroom 3.
My upgrade, done by a professional technician, involved, wiping my internal hard drive completely (everything was backed up on two external hard drives) the installation of Windows 7 - 64 bit and additional RAM (it now has 8 gigs) When it came to re installing the Pixel Benders it was a nightmare. I had to make several calls to Adobe technical support before it would download I even had to allow the technician to access my computer. The next problem was that the Pixel Benders would no work. I looked at the Adobe Forum and found that others had experienced the same problem. One solution seemed to be to install a graphics card with more MB, I therefore bought a GeForce GTSD 250 that has 1 GB of RAM. Whereas the 65 pictures in my Pixel Bender folder are 2000 pixels on the longest edge using my new system and graphics card the Pixel Bender filters will not work on any image that is more than 1000 pixels on the longest edge. Can anyone out there explain the reason for this?

Please make sure you have installed the latest graphics drivers, from http://www.nvidia.com/Download/index.aspx?lang=en-us, for your graphics card.

Pixel bender error in ps cs4

first off specs of my system I am running a kit with an asus dx58so mobo, I7 core, 6gb ddr3 ram, dual geforce gtx 295 graphics card (triple monitor setup two hp and a wacom cintiq) with two 1tb sata harddrives, xp pro 64bit.
I have web design premium cs4, I have always had problems running opengl on the system using my cintiq (3d won't work unless I set my cintiq to be the primary monitor)
anyway I had pixel bender toolkit installed with WDP CS4 and but everytime I try to launch the pixel bender gallery from ps I get an error message: "a pixel bender error occurred: " nothing else, the pixel bender toolkit launches fine, but I thought perhaps since it did work once, I needed to update it, checked the newest version of pixel bender toolkit and downloaded it since it was the newer version as well as the pixel bIender plugins, have installed (both 32 and 64 bit)
I then proceeded to uninstall install both versions of the plugin (separately not together) and tested both, same result. I assumed the install of pixel bender toolkit would uninstall previous versions, which it did not, so I thought that I should uninstall via control panel, but to no avail the uninstaller wouldn't allow me to uninstall pixel bender toolkit by itself, so I can't uninstall, at least not that way.
anyway, I then decided to check if it was simply the version of my nvidia driver, downloaded and updated those drivers, and now, not only do I get the error from photoshop but when I open pixel bender toolkit as a standalone, I get this warning: "theere wasn an error testing your video card capabilities. Please make sure your card is on the approved list" well they are sooooo, I believe I have a compound problem something interferring with the launch via photoshop and now a graphics driver issue.
one thing else, I did install some pixel bender filters from adobe exchange, perhaps one of them affected pixel bender? I had installed them a long time ago, could someone refresh my memory of what a proper install of filters for pixel bender would be? perhaps I placed the files in the wrong directory.
many thanks beforehand for any help you can provide
(I apologize for the grammer, I was typing this a thousand miles a second, I have a ton to do today)

Turn off dual GPU usage in your card prefs.

Where is pixel bender directory used by Photoshop CS5.1 (from Creative Suite 5.5 Web Premium)?

CS5.1 does not appear to use the Pixel Bender Files directory in the Adobe Directory. If I add a new pixel bender filter (.pbx) to the other filters in that directory, it does not show up in the Pixel Bender Filters Gallery from within Photoshop. Actually, the listing of the filters from within Photoshop Pixel Bender Filter Gallery and the filters in the /Adobe/Photoshop CS5.1 (64bit)/Pixel Bender Files are different. Any explanation?

This is Adobe Contribute forum, you can post this query on http://forums.adobe.com/community/photoshop .

The Pixel Bender plugin for Photoshop CS4 is still available at http://www.adobe.com/devnet/pixelbender.html. Pixel Bender filters will work in both After Effects CS4 and Photoshop CS4.

Photoshop CS4, Pixel Bender, Mavericks OS ERRORS

I recently upgraded to Mavericks and am using Photoshop CS4. When I attempt to use Pixel Bender Filters, I get the following error messages for all of the plugins:
ERROR: (line0): require metadata “namespace” of wrong type.
Expected string
ERROR: (line0) required metadata “vendor” of wrong type. Expected string
ERROR: (line 0) required metadata “version” of wrong type. Expected int
I have no clue what is going on. PSD files that have Pixel Bender filters applied on Smart Objects will open but simply attempting to turn off one of the filters causes Photoshop to crash.
HELP!

Hi there,
I have made some serious progress with this. I too was having difficulty with Pixel Bender in Mavericks and have tried with CS4,5,6 and CC. This morning I had a major breakthrough on CS5. I have successfully loaded and run the Pixel Bender plugins. I am however still crashing when attempting to run the Fractal Explorer plugins. Here is what you may need to do to correct the error messages and any issues loading with the Adobe Extension Manager.
1. Download this plugin Pixel Bender Accelerator for Photoshop and follow their direction to place the plugin - http://aescripts.com/pixel-bender-accelerator-for-photoshop/#upgrade-notice
2. Download and run the CS5 Extension Manager update (I used the 5.0.3 version) - Adobe Extension Manager Updates Downloads
3. Install the Pixel Bender Plugin through the updated Extension Manager and "replace all" if necessary.
I think that covers any steps I made to correct this. All the filters in the Pixel Bender gallery work except for the Fractal Explorer plugins at this point, and I believe thats a RAM issue I am having. Please let me know if this helps and if you discover anything along the way.
30 min later...
I just solved the last issue and ran the fractal explorer filters successfully. Once you have the Pixel Bender library accessible in Photoshop, run the Pixel bender accelerator with your image open and saved as a smart object. Once you have applied the accelerator all filter can be used in the pixel bender gallery. No crashing or error messages!!

Pixel Bender problems

I used the Oil Paint filter on an image, but when I then tried to use the Brush Stroke filter, it was grayed out (along with several other filters).. I converted the original image to a smart object before applying the Oil Paint filter in Pixel Bender. The technique is one used in a Kelby tutorial, but in that one the instructor used the Brush Stroke filter. Nobody in the Pixel Bender forum has an answer. In addition, I tried to uninstall the plug-in and Extension Manager said I lacked the appropriate permission to remove Pixel Bender. I am logged in as Adminstrator, so I don't know what further permission I might need.

Is your image 16 bits/channel and is that one of the pixel bender filters or Photoshop filter effects filter
Filter>Brush Strokes?
Try converting your image to RGB color and 8 bits/channel. Image>Mode.
To uninstall the pixel bender filter right click on the extension manager shortcut and choose Run as Administrator.

Pixel Bender metadata hinting proposal

I put this on my blog earlier, but I wanted to repost here for discussion.This was what I wrote:
We tried to be semantically agnostic in the original design of the Pixel Bender language. We'd seen other languages go down rabbit holes of over-specification around what parameters really meant, locking them into archaic and insufficient implementations or clumsy hierarchies of meanings. We didn't want to limit Pixel Bender developers into what we could conceive at the time of the invention of the language.
We were being a bit too idealistic :). It is completely true that the community of Pixel Bender developers continues to blow our minds at what they accomplish with the language and we never would have anticipated half the stuff that you guys are using Pixel Bender for. However, having some generally useful semantic meanings for Pixel Bender parameters would definitely help those who design general user interfaces for Pixel Bender filters.
One smart thing we did (if I do say myself) was to allow parameter and kernel metadata to be extensible. It provided developers like After Effects and Picnik a way to add custom metadata to Pixel Bender that specified semantics or actual UI controls for Pixel Bender kernels and graphs. The picnik metadata and the After Effects metadata are different though. I started to get concerned that by not having something around this that we could end up with many different Pixel Bender semantic metadata mechanisms floating around. To that end, I created the proposal below and started floating it around Adobe and some of the sites that are heavy users of Pixel Bender.
In this design, I tried to follow some general rules:
Pixel Bender is not only a way to write image and video filters for Adobe applications, but also a way for you to host 3rd party filters in your Flash-based applications. Any guidelines we create need to be implemented by us, but also by any independent Flash developers creating apps that use Pixel Bender kernels. To that end, I tried to keep the design relatively simple so that it wouldn't be too difficult to implement in Flash.
This proposal adds semantic metadata, but avoids specifying specific user interface controls. Rather than specifying a slider as an editor for a parameter, I think it makes more sense to say that the parameter is a percentage and allow someone designing a UI to make a good percentage editor. We are definitely thinking about how to specify custom editor UIs for Pixel Bender filters, but this proposal does not approach that.
The proposal is not a complete answer for all Pixel Bender filters. I'm trying to get the most universal semantics represented. The most generally useful, as opposed to trying to give the complete solution. If you have an application that is uses Pixel Bender kernels for something that makes sense to augment the metadata you can still choose to do so.
The proposal represents guidelines, not requirements. As a developer consuming Pixel Bender kernels, you can choose to enumerate the metadata as described in the proposal or not. The suggested metadata is metadata. It is not required. The goal is that if you wish to take advantage of it when it is present, that you can provide a more compelling user interface to your users because you understand the intent of a parameter, not just its type.
There are a couple open questions in the proposal that I'd like feedback on. They are called out pretty clearly. I'd really like your feedback on this proposal. I hope to issue the final version soon. Reply to this post or in the Pixel Bender forums on Adobe Labs. If you decide to post a reply on your own blog, please post a link to your post here or in the forum. Right now trackbacks are off so I won't know about it otherwise. You can also tweet a reply to the Pixel Bender twitter account (if you can fit it in 140 characters ).

Overall I like the proposal. To address the issues called out:
For both integers and floats concerning a "time", I think it is best
to have that be relative to the time that the filter has been running.
The time a filter is running would be determined by context the filter
is being used in. For video I can see it being tied to video time,
while for a filter being applied to an image it probably corresponds
to how much real time the filter has been running. The general idea
being that if I run my application multiple times I should expect to
see the same results, which is harder to do if time is tied to actual
time versus relative time. If that makes any sense.
I am not in favor of the InputSizeX types. While I understand the
desire to have the image size is a common request, given the ability
to chain filters it promotes a false sense of accuracy. Better to let
people have workarounds with known caveats instead of a semi supported
standard.
As a side note, the mousePos example on page 8 is specified as float2,
but the values only contain 1 number.
