GLCapabilitiesChooser result should be between 1 and 6

All,

My application crashes with the following exception:

Exception in thread "main" javax.media.opengl.GLException: Invalid result 11 from GLCapabilitiesChooser (should be between 1 and 6)
	at com.sun.opengl.impl.windows.wgl.WindowsWGLGraphicsConfigurationFactory.updateGraphicsConfiguration(WindowsWGLGraphicsConfigurationFactory.java:264)

Why should the result be between 1 and 6? I am certain that my machine supports the capabilities I have requested.

Thank you,
Robert

#2

Which capabilities have you requested?

#3

Gouessej,

I have requested setSampleBuffers(true) and setNumSamples(2).

Thank you,
Robert

#4

Ok you try to use FSAA, it should not crash, it should disable FSAA silently if not available, it is a regression on my view. Which graphics card do you have?

#5

Gouessej,

I have an ATI Mobility Radeon 9700.

Thank you,
Robert

#6

Your graphics card has 6 samples. What happens when you increase the sample count (setNumSamples(6))?

I have almost the same graphics card at home (ATI Radeon 9250 Pro) that supports 2 to 6 samples. Can you provide me a tiny test case to reproduce your bug?

#7

Gouessej,

I have attached a zip (renamed txt) containing a program that crashes with the exception. Note the build and run scripts set the classpath to jogl jars in the current directory, I would have included them in the zip, but that would be over 1500KB.

Thank you,
Robert

Gouessej,

Requesting 4 samples crashes with result 12 should be between 1 and 4. Requesting 6 samples crashes with result 13 should be between 1 and 2.

Thank you,
Robert

#9

Gouessej,

I have tested this on another machine with a NVIDIA Quadro FX 3450/4000 SDI card. This card supports on up to 6 sample buffers as well. My application will crash on this machine if I request a sample buffer count other than 2. Also, if I include the following in my requests, the program will crash even when requesting 2 sample buffers.

capabilities.setBackgroundOpaque(false);
capabilities.setAlphaBits(8);

Thank you,
Robert

Ok I will give it a try as soon as possible. I hope it is reproducible under Linux as I have still no access to Windows.

#11

Hi, this problem sounds familiar to me.
I use the JOGL 2.0 AMD64 binaries on a NVidia GTX 260m (supporting 16x FSAA) and I get the following errors for each FSAA sample buffer size using a glCanvas (it is all fine for a glJPanel):

at com.sun.opengl.impl.windows.wgl.WindowsWGLGraphicsConfigurationFactory.updateGraphicsConfiguration(WindowsWGLGraphicsConfigurationFactory.java:264)

0,1,2: ok
4: Invalid result 31 from GLCapabilitiesChooser (should be between 1 and 24)
8: Invalid result 43 from GLCapabilitiesChooser (should be between 1 and 16)
16: Invalid result 55 from GLCapabilitiesChooser (should be between 1 and 8)

#12

Yes it is the same problem. I’m sorry, I’m currently very busy but I will try to fix it when I have some spare time.

Edit.: my home computer is a bit broken, it does not help…

#13

I and my colleagues have the same issue on various Windows versions and JOGL 2

The problem seems to be that wglChoosePixelFormatARB in WindowsWGLGraphicsConfigurationFactory.updateGraphicsConfiguration returns a number of pixel formats that is less than the nr of available capabilities returned by WindowsWGLGraphicsConfiguration.HDC2GLCapabilities. The recommended pixel format passed on to the chooser (and which is always returned by it) seems always greater than numFormats for us. If we set more than 2 samples it causes: throw new GLException("Invalid result " + pixelFormat + " from GLCapabilitiesChooser (should be between 1 and " + numFormats + “)”);

I hope this may help a bit in finding out why it actually happens cause that I unfortunately do not know yet.

#14

Thank you. It helps a lot as I have no machine under Windows to reproduce this bug.

#15

That must be a bit hard to fix a problem you can’t reproduce. Just ask if you need some more info or need something tested.

#16

Thanks. In my humble opinion, it is a regression between JOGL 1.1.2 and JOGL 2.

#17

All,

 Where should this bug be posted so that it can receive more attention?

Thank you,
Robert

#18

hi Robert,
sorry for the delay. So you are using JOGL 2? Could you try one of those builds (I hope you are not on a mac ;)) and report back if it still happens.

#19

bienator,

 I am using JOGL 2 and Windows XP.  With the suggested build, my application crashes on:

capabilities = new GLCapabilities(GLProfile.getDefault());

The stack trace is:
