Detailed Description

Platform interface class for the OpenGL drawing surface that uses OpenGL ES 2.0 and EGL. Users can either have this class create an OpenGL context for them or provide an existing context for the drawing surface to use.

This class should be set up as follows:

TSLOpenGLSurfaceCreationParameters framebufferSettings;
// Set desired options on framebufferSettings
 
EGLint eglConfigID = TSLNativeEGLSurface::preferredConfigID( nativeDisplay, framebufferSettings )
if( eglConfigID == -1 )
{
   // Error - no suitable framebuffer configuration found
}
 
EGLDisplay display = eglGetDisplay( nativeDisplay );
 
EGLint attrs[] = { EGL_CONFIG_ID, eglConfigID,
                   EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT, // We require ES2 support
                   EGL_NONE };
EGLConfig desiredConfig;
EGLint numConfigs = 0;
if( !eglChooseConfig( m_display, attrs, &desiredConfig, 1, &numConfigs )
   || numConfigs == 0 )
{
   // Error - could not look up config details
}
 
EGLint visualID = 0;
eglGetConfigAttrib( m_display, m_config, EGL_NATIVE_VISUAL_ID, &visualID );
 
// Create window using native visual ID if applicable for the windowing system
 
TSLNativeEGLSurface *surface = new TSLNativeEGLSurface( nativeDisplay, nativeWindow, eglConfigID, framebufferSettings );
if( surface->requiresDeviceCapabilities() )
{
   surface->setDeviceCapabilities( ... );
}

This drawing surface requires graphics hardware that is OpenGL ES 2.0 compliant.

Hardware with support for the following OpenGL extensions is recommended, but not required:

GL_OES_element_index_uint
GL_OES_standard_derivatives

Non-Native Rendering

Non-native rendering is not supported with this drawing surface.

◆ TSLNativeEGLSurface() [1/3]

TSLNativeEGLSurface::TSLNativeEGLSurface	(	EGLNativeDisplayType	nativeDisplay,
		EGLNativeWindowType	nativeWindow,
		EGLint	configID,
		const TSLOpenGLSurfaceCreationParameters &	creationProperties )

Constructs a new drawing surface, creating a new OpenGL context for the given window. The drawing surface owns the context created.

To check if the drawing surface has successfully attached, check that the context() method returns non-zero.

Parameters

nativeDisplay	The host type native display connection for the drawing surface to use.
nativeWindow	The host type native window to attach the drawing surface to.
configID	The EGL framebuffer configuration ID that the drawing surface should use. This can be retrieved from the preferredConfigID() method.
creationProperties	Options that affect the creation of the drawing surface. See the documentation for TSLOpenGLSurfaceCreationParameters for the available options.

◆ TSLNativeEGLSurface() [2/3]

TSLNativeEGLSurface::TSLNativeEGLSurface	(	EGLDisplay	display,
		EGLSurface	window,
		EGLContext	context,
		const TSLOpenGLSurfaceCreationParameters &	creationProperties )

Constructs a new drawing surface, using the existing OpenGL ES context passed in. The drawing surface does not assume ownership of this context.

To check if the drawing surface has successfully attached, check that the context() method returns non-zero.

Parameters

display	The EGL display connection for the drawing surface to use.
window	The EGL surface to attach the drawing surface to.
context	The existing OpenGL ES context. This context should have already been made current in the current thread.
creationProperties	Options that affect the creation of the drawing surface. See the documentation for TSLOpenGLSurfaceCreationParameters for the available options.

Member Function Documentation

◆ attach()

bool TSLNativeEGLSurface::attach	(	EGLDisplay	display,
		EGLSurface	window,
		EGLContext	context )

Attaches the drawing surface to the given window using the given OpenGL context. This will detach the drawing surface from any window it is currently attached to.

Parameters

display	The EGL display connection for the drawing surface to use.
window	The EGL surface to attach the drawing surface to.
context	The existing OpenGL ES context. This context should have already been made current in the current thread.

Returns: true if the surface was attached successfully, false otherwise. If this method returns false the drawing surface cannot be used until it is successfully reattached.

◆ caw()

virtual TSLOpenGLSurface * TSLNativeEGLSurface::caw ( )

virtual

Reimplemented from TSLEGLSurface.

◆ context()

EGLContext TSLNativeEGLSurface::context ( )

Returns the OpenGL context used by the drawing surface. If this returns EGL_NO_CONTEXT, the drawing surface did not attach successfully and cannot be used.

◆ makeContextCurrent()

bool TSLNativeEGLSurface::makeContextCurrent ( )

Binds the OpenGL context held by the drawing surface to the current thread. This method can be used to change the thread used for drawing to the drawing surface.

Returns true if the context was made current in this thread, or false if there was an error or the drawing surface was not attached.

◆ preferredConfigID()

static EGLint TSLNativeEGLSurface::preferredConfigID	(	EGLNativeDisplayType	nativeDisplay,
		const TSLOpenGLSurfaceCreationParameters &	creationProperties )

static

Returns the ID of the EGL framebuffer configuration that the drawing surface would prefer to use given the requested settings.

Only configurations that support the following will be considered:

Configurations that support OpenGL ES 2.0 as specified by EGL_OPENGL_ES2_BIT
Configurations that have RGB colour buffers
Configurations that have a depth buffer of at least 16 bits.

Regardless of any optional parameters, framebuffer configurations with the following are always preferred:

Configurations with the highest red/green/blue colour channel size, with no minimum size.
Configurations with the highest depth buffer size, with a minimum size of 16 bits.
Configurations with the greatest number of samples, up to the requested number of samples.

Configurations with a sample buffer will be preferred over configurations without one.

Returns the EGL config ID of the framebuffer configuration that the drawing surface would prefer to use.

◆ terminateDisplayOnDestruction()

void TSLNativeEGLSurface::terminateDisplayOnDestruction ( bool shouldTerminate )

Controls whether eglTerminate will be called on the EGLDisplay when this drawing surface is destroyed. If multiple drawing surfaces or OpenGL contexts are in use at the same time from the same native display, this method should be invoked on all surfaces to avoid the deletion of one drawing surface invalidating all OpenGL contexts created from the display.
