AA is gone in 2.0rc2!?

[EgonOlsen]

Hi,

i've just ported jPCT to 2.0rc2. Everything works fine except for anti aliasing...it's gone. I'm doing this:

Display.create(new PixelFormat(bpp, 0, zbpp, 0, samples));

No matter which value i'm using for samples, it always gives me a

org.lwjgl.LWJGLException: Failed to find ARB pixel format 1 0

	at org.lwjgl.opengl.WindowsPeerInfo.nChoosePixelFormat(Native Method)
	at org.lwjgl.opengl.WindowsPeerInfo.choosePixelFormat(WindowsPeerInfo.java:52)
	at org.lwjgl.opengl.WindowsDisplay.createWindow(WindowsDisplay.java:177)
	at org.lwjgl.opengl.Display.createWindow(Display.java:300)
	at org.lwjgl.opengl.Display.create(Display.java:816)
	at org.lwjgl.opengl.Display.create(Display.java:744)

I don't know about 2.0rc1, but in 1.1.4, the exact same code was working fine and gave me some nice AA. Any ideas?

This is on a Radeon 4870, Catalyst 8.8, Windows Vista

please give 2.0rc1 a whirl - spasi changed some stuff around for OGL3.

In 2.0rc1, everything works fine. AA is present as it should be.

strange - I'll poke spasi when I see him

On my work machine (Nvidia Quadro 290...unknown driver...), AA works fine. So i can now choose between home (no AA, but sound) and work (AA, but no sound) with rc2...

I committed a possible fix, let me know if it still isn't working.

I have nothing installed to compile this native stuff myself. Is the modified dll already part of the rc2-distribution? If not, could you please provide me with a compiled version?

try this one:

Thank you, but it doesn't help...  Still no AA on ATI with this dll.

Do you get the same error if you set samples to 0 or 1?

[EgonOlsen]

Do you get the same error if you set samples to 0 or 1?

0 works fine...it always did. Everything else doesn't work. However, the exception has changed with the new dll to:

Failed to find ARB pixel format 0 0

(the 1 is a 0 now...everything else remains the same)

[elias]

Note that the legacy wglChoosePixelFormat (not ARB) code path is probably selected when samples = 0.

I noticed the same issue (no multisampling) on NVidia Quadro FX 2500M, 177.98 (Vista 32bit)
RC1 worked fine.

[spasi]

Sorry for the delay, was busy at work.

It should be fixed now, try out this new dll and let me know if it's working.

Thanks a lot!
It works now as it did with RC1.
