WorldWindowGLCanvas is a lightweight Swing component for displaying WorldWind Models (globe and layers). It's a self-contained component intended to serve as an application's WorldWindow. Construction options exist to specify a specific graphics device and to share graphics resources with another graphics device.

Note: The Java SDK for OpenGL (JOGL) support for the underlying GLJPanel that this class uses has historically been problematic. It works well on some devices but not on others, and its performance varies much more among devices than that of its heavyweight counterpart, WorldWindowGLCanvas. It's therefore best to use the heavyweight component if possible. You can find detailed information on this issue in the Heavyweight and Lightweight Issues section of the "JOGL User's Guide"

This class is capable of supporting stereo devices. To cause a stereo device to be selected and used, specify the Java VM property "gov.nasa.worldwind.stereo.mode=device" prior to creating an instance of this class. A stereo capable SceneController such as StereoSceneController must also be specified in the WorldWind Configuration. The default configuration specifies a stereo-capable controller. To prevent stereo from being used by subsequently opened WorldWindowGLCanvases, set the property to a an empty string, "". If a stereo device cannot be selected and used, this falls back to a non-stereo device that supports WorldWind's minimum requirements.

Under certain conditions, JOGL replaces the GLContext associated with instances of this class. This then necessitates that all resources such as textures that have been stored on the graphic devices must be regenerated for the new context. WorldWind does this automatically by clearing the associated GpuResourceCache. Objects subsequently rendered automatically re-create those resources. If an application creates its own graphics resources, including textures, vertex buffer objects and display lists, it must store them in the GpuResourceCache associated with the current DrawContext so that they are automatically cleared, and be prepared to re-create them if they do not exist in the DrawContext's current GpuResourceCache when needed. Examples of doing this can be found by searching for usages of the method GpuResourceCache.get(Object) and GpuResourceCache.getTexture(Object).
