How to use hardware acceleration in Java 2D

Hi,
I searched in net and could not find anything clear on hardware acceleration using Java 2D/Swing.
To use the hardware acceleration, do I need to specify
-Dsun.java2d.opengl=true ? Is this must?
Without specifying this, Java 2D calls wont use hardware acceleration?
Kindly clarify. I could not able to find anything in net for this.
I am having ATI Radeon AGP card and using Linux as OS. I have installed the ATI driver. Now I need to know how to interact with hardware using Java2D/Swing.

Hi,
Does anyone know how to be able to use the iPAQs harware buttons and joystick in Suns Personal Java?
I moved a Tetris applet i have written for PC's to the iPAQ and it works except for the arrow keys that i use to control it with.
Any help would be greatly appreciated!

I have the same problem.
Does anyone know how to use the buttons of the iPAQ for your java applications?

How to use hardware accelerated css transition to move an element smoothly

Hello All,
I have created an element twice the width of my stage, and would like it to move across the screen when a button is clicked. The problem is that the animation is not smooth at all. It stutters and gasps like an old car! I was wondering if it is possible to use a hardware accelerated css transition to make it move more smoothly. If this is possible could someone please give me example of what code to write and where?
Thanks and all the best!

There's a few ways to do it, but I'd use a style sheet. So:
1. Add this to the "creationComplete" Stage event: sym.$("<link rel='stylesheet' type='text/css' href='styles.css'>").appendTo("#Stage");
2. Create a style sheet (text file) in your project folder named "styles.css", and define a class:
.force-webkit-acceleration {
-webkit-transform: translate3d(0,0,0);
3. Give your animated element the class "force-webkit-acceleration" in the properties panel (the little c-in-a-box icon next to the title field).
Be sure that the style sheet file ends up in your "publish/web" folder too.

Finaly. How to enable hardware acceleration for X-

After much discussion on this form and with my friends, I've finally cracked hardware acceleration for X-FI on Vista. It works by using Alchemy on a large scale and gives acceleration for everything you listen to. The breakthrough finally came through thanx to help and info I received from alexs3ds on this thread?http://forums.creative.com/creativel...message.id=645?It started as an emulation concept discussion and evolved in to this. It gives all your 3D audio effects and EAX in games without game by game transmutation and I have noticed a large quality and volume enhancement in normal music and film audio because even that is now accelerated. Here's a step by step guide on how to do it.[color="#ff0033">?[color="#3366ff">Download Alchemy and install. Get it here .[color="#3366ff">http://preview.creativelabs.com/alchemy/default.aspx[color="#3366ff">?[color="#3366ff">Open a?window in explorer and go to [color="#3333ff">Windows\System32.[color="#3366ff">?[color="#3366ff">Locate the file dsound.dll and right click on it then select properties.[color="#3366ff">?[color="#3366ff">Click the security tab then click advanced.[color="#3366ff">?[color="#3366ff">In the advanced security panel?that opens up, click the owner tab then edit.[color="#3366ff">?[color="#3366ff">Use this to set your user account name as owner.

You can't use 24-Bit audio samples. You can however reverse the process and regain support. The Alchemy drivers can cause a bit of choppy sound now and then if you don't configure them right. See the Alchemy advanced FAQ for info. Plus, remember they are Beta. You can however update your system as and when alchemy updates. It's not known if every game will work with EAX or 3Dsound with this. To my knowledge?all, if not?most do.You can still edit and add game settings to the dsound.ini file. For help and info in getting the best quality out of your X-FI and a list of what XP software you can install off your driver disk that came with your card refer to this thread. http://forums.creative.com/creativel...essage.id=6029?Enjoy. Edit:- IMPORTANT UPDATE?This will only work if your card is set in game mode. It will not work properly in any other mode. See my post further down this thread for more details.Also important is that I have only been able to test this on Vista 32 ultimate. It is untested in any other version of Vista. Perhaps people who have it running on other versions of Vista could post this info and help put together a list. ?

It does work, however I discovered more?important conditions. You MUST have your audio card in game mode BEFORE you do this. The reason is that the alchemy file passes the audio to OpenAL in game mode only. IF YOU TRY TO RUN GAMES IN ANY OTHER MODE YOUR SYSTEM WILL CRASH WITH BSD. IF YOU TRY TO RUN MEDIA PLAYER IT WILL HANG. IF YOU RUN DIRECTX DIAGNOSTIC YOUR SYSTEM WILL CRASH WITH BSD. YOUR?CARD MUST BE IN GAME MODE. IF YOU TRY TO CHANGE TO GAME MODE AFTER THE SWITCH, YOU WILL NOT BE ABLE TO AS THE AUDIO PANEL WON'T LOAD. DO IT BEFORE YOU SWITCH. As for windows replacing files after reboot, that aint happening to me. I've looked everywhere and can't find any sign of?were replacement files would come form either. Not that I'm saying it isn't happening, Vista is supposed to have a security system that stops you from replacing core system files. It just ain't happening in my system. However, I do have various system hacks in place and one of them may be stopping this. Need to look in to this. Fact:- I'm sitting with this in system now ( got no intentions of going back cause the audio's great ). I've tested 0 up-to date games and all give EAX etc. Without transmutation. Audio sounds amazing compared to what it was before and video audio finely plays in sync ( hurray). Maybay I should add a warning to this mod that you must only try it if you know what you are?doing.BTW in case this has anything to do with it, my system is :-
Asus?am2 with nforce 4, amd am2 x2 dual core cpu, 2 gig dual channel ddr2 800, oem?SB X-FI and Vista 32 ultimate.

How to Enable Hardware Acceleration in FireFox 31

Please advise how to enable hardware acceleration in FireFox 31. All my graphics and other hardware/software is current and updated. I've also paired my Bookmark Toolbar down to under 20 entries.
FireFox is so sluggish that just a few open tabs cause the pausing "wheel of doom" every time I try to enter information or go to another part of the website. Sometimes the pauses are 5-10 seconds, sometimes a minute or more.
I do not have this issue on the other browsers that I use.
Thank you in advance for your help!

Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
*Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
*Do NOT click the Reset button on the Safe Mode start window
*https://support.mozilla.org/kb/Safe+Mode
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
You can also check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
*http://kb.mozillazine.org/Profile_folder_-_Firefox
*http://kb.mozillazine.org/Multiple_profile_files_created
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).

How to use C-Structure in java applets

public void paint(Graphics g)
it gives error message... how can � use struct model in java applets???
if you help me i will be greatfull....

� use import but it doesn't work.
i add: import renk; or import class renk;
how will � add import I assumed based on your initial post that the renk and benek classes were in the same file. Apparently you're saying they are not. So for another thing, make your renk class "public class renk", and add the "public" keyword to the 3 members of that class. Then if your code still doesn't see the "renk" class, it would just be that you don't have the directory that contains the compiled "renk.class" in your classpath.

How to use " toFront() " method in java application and in which package or class having this toFront() method.if anybody know pl. send example.

The API documentation has a link at the top of every page that says "Index". If you follow that and look for toFront(), you will find it exists in java.awt.Window and javax.swing.JInternalFrame.
To use it in a Java application, create an object x of either of those two classes and write "x.toFront();".

Flash Player often crashes if using hardware acceleration.

Hi, guys. Flash Player crashes. It crashes when the "Use hardware acceleration" checkbox is checked. And it crashes so bad, that only the Reset button helps.
My PC is flawless. I'm running Winsows XP x64 SP2 (latest service pack for this OS), Nvidia Geforce 8600GT with latest drivers, DirectX 9c, Flash Player 10.3.
If I disable hardware acceleration in the Flash Player settings, there are no crashes. Without HW acceleration videos are a little aliased and ugly.
Why is that happening?

Hi,
I'm sorry you're running into these problems. Could you follow the instructions on our video troubleshooting page and in addition to opening a bug report, please send the results to me at [email protected]? I'll take a look and see if I notice anything out of place.
Thanks,
Chris

Is JMF use hardware accelerated through JNI possible?

Dear all:
I try to use JMF decode MPEG-2 data, through VeXP which wrote in C.
So I think we can call C library through JNI pass encoded MPEG-2 data to VeXP, use hardware decode encoded MPEG-2 data to YUV-format raw data then return it to JAVA.
but JNI seem can't pass media raw data by call by reference...
It should cause a lot of memory copy.
How about it's feasibility?
Have anyone give me some suggestion?
Regards,
white

Mercury Playback Engine doesn't use hardware acceleration in Premiere CC

although hardware acceleration was supposed to be better in Premiere CC, it stopped working completly for me. The option to hardware accelerate is grayed out

It worked pretty ok in CS 6 (apart from system freezes when using CUDA…) . Kind of a let down. Please help.

With this "hack" I was able to enable the CUDA acceleration. I inserted "GeForce GT 650M" in the aforementioned textfile (without "Nvidia"). Before that I also could only use software acceleration.
Now with my machine I think I should also be able to use OpenCL, right? How do I get this option? These are my specs:
