Public Member Functions | |
OpenGLESFBOTextureTarget (OpenGLESRenderer &owner) | |
void | activate () |
Activate the render target and put it in a state ready to be drawn to. | |
void | deactivate () |
Deactivate the render target after having completed rendering. | |
bool | isImageryCache () const |
Return whether the RenderTarget is an implementation that caches actual rendered imagery. | |
void | clear () |
Clear the surface of the underlying texture. | |
Texture & | getTexture () const |
Return a pointer to the CEGUI::Texture that the TextureTarget is using. | |
void | declareRenderSize (const Sizef &sz) |
Used to declare to the TextureTarget the largest size, in pixels, of the next set of incoming rendering operations. | |
bool | isRenderingInverted () const |
Return whether rendering done on the target texture is inverted in relation to regular textures. | |
Static Public Member Functions | |
static void | initializedFBOExtension () |
initialize FBO extension functions pointers | |
Protected Member Functions | |
void | initialiseRenderTexture () |
allocate and set up the texture used with the FBO. | |
void | resizeRenderTexture () |
resize the texture | |
String | generateTextureName () |
generate a texture name | |
Protected Attributes | |
GLint | d_oldFbo |
Saving fbo before activation. | |
GLuint | d_frameBuffer |
Frame buffer object. | |
GLuint | d_texture |
Associated OpenGLES texture ID. | |
OpenGLESTexture * | d_CEGUITexture |
we use this to wrap d_texture so it can be used by the core CEGUI lib. | |
Static Protected Attributes | |
static const float | DEFAULT_SIZE |
default size of created texture objects | |
static uint | s_textureNumber |
static member var used to generate unique texture names. |
OpenGLESFBOTextureTarget - allows rendering to an OpenGLES texture via FBO.
void CEGUI::OpenGLESFBOTextureTarget::activate | ( | ) | [virtual] |
Activate the render target and put it in a state ready to be drawn to.
Reimplemented from CEGUI::OpenGLESRenderTarget< TextureTarget >.
void CEGUI::OpenGLESFBOTextureTarget::deactivate | ( | ) | [virtual] |
Deactivate the render target after having completed rendering.
Reimplemented from CEGUI::OpenGLESRenderTarget< TextureTarget >.
void CEGUI::OpenGLESFBOTextureTarget::declareRenderSize | ( | const Sizef & | sz | ) | [virtual] |
Used to declare to the TextureTarget the largest size, in pixels, of the next set of incoming rendering operations.
sz | Size object describing the largest area that will be rendererd in the next batch of rendering operations. |
InvalidRequestException | May be thrown if the TextureTarget would not be able to handle the operations rendering content of the given size. |
Implements CEGUI::TextureTarget.
Texture& CEGUI::OpenGLESFBOTextureTarget::getTexture | ( | ) | const [virtual] |
Return a pointer to the CEGUI::Texture that the TextureTarget is using.
Implements CEGUI::TextureTarget.
bool CEGUI::OpenGLESFBOTextureTarget::isImageryCache | ( | ) | const [virtual] |
Return whether the RenderTarget is an implementation that caches actual rendered imagery.
Typically it is expected that texture based RenderTargets would return true in response to this call. Other types of RenderTarget, like view port based targets, will more likely return false.
Implements CEGUI::RenderTarget.
bool CEGUI::OpenGLESFBOTextureTarget::isRenderingInverted | ( | ) | const [virtual] |
Return whether rendering done on the target texture is inverted in relation to regular textures.
This is intended to be used when generating geometry for rendering the TextureTarget onto another surface.
