| OGLSurfaceData | | abstract public class OGLSurfaceData extends SurfaceData (Code) | | This class describes an OpenGL "surface", that is, a region of pixels
managed via OpenGL. An OGLSurfaceData can be tagged with one of three
different SurfaceType objects for the purpose of registering loops, etc.
This diagram shows the hierarchy of OGL SurfaceTypes:

OpenGLSurfaceRTT
OpenGLSurface
This kind of surface can be rendered to using OpenGL APIs. It is also
possible to copy an OpenGLSurface to another OpenGLSurface (or to itself).
This is typically accomplished by calling MakeContextCurrent(dstSD, srcSD)
and then calling glCopyPixels() (although there are other techniques to
achieve the same goal).
OpenGLTexture
This kind of surface cannot be rendered to using OpenGL (in the same sense
as in OpenGLSurface). However, it is possible to upload a region of pixels
to an OpenGLTexture object via glTexSubImage2D(). One can also copy a
surface of type OpenGLTexture to an OpenGLSurface by binding the texture
to a quad and then rendering it to the destination surface (this process
is known as "texture mapping").
OpenGLSurfaceRTT
This kind of surface can be thought of as a sort of hybrid between
OpenGLSurface and OpenGLTexture, in that one can render to this kind of
surface as if it were of type OpenGLSurface, but the process of copying
this kind of surface to another is more like an OpenGLTexture. (Note that
"RTT" stands for "render-to-texture".)
In addition to these SurfaceType variants, we have also defined some
constants that describe in more detail the type of underlying OpenGL
surface. This table helps explain the relationships between those
"type" constants and their corresponding SurfaceType:

| Method Summary | |
| public boolean | canRenderLCDText(SunGraphics2D sg2d)
For now, we can only render LCD text if:
- the fragment shader extension is available, and
- blending is disabled, and
- the source color is opaque
Eventually, we could enhance the native OGL text rendering code
and remove the above restrictions, but that would require significantly
more code just to support a few uncommon cases. | | public boolean | copyArea(SunGraphics2D sg2d, int x, int y, int w, int h, int dx, int dy)

| | final int | getTextureTarget()
If this surface is backed by a texture object, returns the target
for that texture (either GL_TEXTURE_2D or GL_TEXTURE_RECTANGLE_ARB). | | final int | getType()
Returns one of the surface type constants defined above. | | native protected boolean | initFBObject(long pData, boolean isOpaque, boolean texNonPow2, boolean texRect, int width, int height)

| dispose | | static void dispose(long pData, long pConfigInfo)(Code) | | Disposes the native resources associated with the given OGLSurfaceData
(referenced by the pData parameter). This method is invoked from
the native Dispose() method from the Disposer thread when the
Java-level OGLSurfaceData object is about to go away. Note that we
also pass a reference to the native GLX/WGLGraphicsConfigInfo
(pConfigInfo) for the purposes of making a context current.

surface.

|
| getRaster | | public Raster getRaster(int x, int y, int w, int h)(Code) | | |
| getTextureTarget | | final int getTextureTarget()(Code) | | If this surface is backed by a texture object, returns the target
for that texture (either GL_TEXTURE_2D or GL_TEXTURE_RECTANGLE_ARB).
Otherwise, this method will return zero.

of the type parameter. If the surface creation fails for any reason,
an OutOfMemoryError will be thrown.
