Hello, kelvin. Tried the thing you exposed, and (not funny) i got this:
version = 1.3.1-beta1 vendor = Sun Microsystems, Inc. specification.version = 1.3 specification.vendor = Sun Microsystems, Inc. renderer = OpenGL
Renderer version = 1.3.3261 WinXP Release doubleBufferAvailable = true stereoAvailable = false sceneAntialiasingAvailable = false sceneAntialiasingNumPasses = 0 textureColorTableSize = 0 textureEnvCombineAvailable = true textureCombineDot3Available = true textureCombineSubtractAvailable = true texture3DAvailable = true textureCubeMapAvailable = true textureSharpenAvailable = false textureDetailAvailable = false textureFilter4Available = false textureAnisotropicFilterDegreeMax = 16.0 textureBoundaryWidthMax = 1 textureWidthMax = 2048 textureHeightMax = 2048 textureLodOffsetAvailable = false textureLodRangeAvailable = true textureUnitStateMax = 6 compressedGeometry.majorVersionNumber = 1 compressedGeometry.minorVersionNumber = 0 compressedGeometry.minorMinorVersionNumber = 2
You will see that antialias is not supported. I have a radeon 9000, and scene antialiasing is supported. I can do it anytime, simply by going through the configuration panel in XP. Is this a known behavior? Do i have to fill a bug report?
This means none of OGL extensions GL_ARB_multisample , GL_EXT_multisample, GL_SGIS_multisample are support by the driver as report by wglGetExtensionsStringARB() or wglGetExtensionsStringEXT(). Besides, the pixel format return by OGL doesn't support 24 bit RGB accumuluation buffer as well in your driver.
Try DirectX version of Java3D, usually it has better antialiasing support and this is probably other applications are using in your machine.
For example, under Nvidia GF2 MX400 driver v6.13.10.4109 OpenGL version of Java3D report
sceneAntialiasingAvailable = true sceneAntialiasingNumPasses = 8 (=> hardware antialiasing not support but accumulation buffer found)
but using DirectX version of Java3D report
sceneAntialiasingAvailable = true sceneAntialiasingNumPasses = 1 (=> hardware support multisample )
QueryProperties is an example program bundle in the Java3D distribution.
Thanks.
