Hi,
Fullscene antialiasing is support in v1.3 release for
both release if the driver support. (Previous Java3D
version for OpenGL did not multisampling
fullscene antialiasing)
To check you graphics card capabilities, run
programs/examples/PackageInfo>java QueryProperties
If sceneAntialiasingNumPasses = 8,
it means multisampling is not support and accumulation
buffer will be used to similulate fullscene antialiasing
under OpenGL.
If sceneAntialiasingNumPasses = 1,
multisampling is support and you should see pretty fast
rendering with antialiasing support.
If sceneAntialiasingNumPasses = 0, full scene
antialiasing is not support. This happen when
DirectX version of Java3D is used and multisampling
is not support by the driver. (since DirectX don't
have accumlation buffer)
To enable fullscene antialiasing, you MUST first
set the GraphicsConfigTemplate3D propertly
instead of using the default in the SimpleUniverse:
GraphicsConfigTemplate3D template = new GraphicsConfigTemplate3D();
template.setSceneAntialiasing(template.PREFERRED);
GraphicsConfiguration config =
GraphicsEnvironment.getLocalGraphicsEnvironment().
getDefaultScreenDevice().getBestConfiguration(template);
Then set
View.setSceneAntialiasingEnable(true);
Setting only the last one without initialize the
GraphicsConfigTemplate3D will not see multisampling
fullscene antialiasing effect even though driver
support it.
There is also a new properly added in v1.3 release.
This is from README
===========================
Multisampling Antialiasing
===========================
By default, full scene antialiasing is disabled if a
multisampling pixel format (or visual) is chosen.
To honor a display drivers multisample antialiasing
setting (e.g. force scene antialiasing), set the
implicitAntialiasing property to true.
This causes Java3D to ignore its own scene antialias
settings, letting the driver implicitly implement the
feature.
java -Dj3d.implicitAntialiasing=true MyProgram
Thanks.
