OpenGLWGLPBTextureTarget - allows rendering to an OpenGL texture via the pbuffer WGL extension. More...
Public Member Functions | |
OpenGLWGLPBTextureTarget (OpenGLRenderer &owner) | |
void | activate () |
Activate the render target and put it in a state ready to be drawn to. More... | |
void | deactivate () |
Deactivate the render target after having completed rendering. More... | |
void | clear () |
Clear the surface of the underlying texture. | |
void | declareRenderSize (const Size &sz) |
Used to declare to the TextureTarget the largest size, in pixels, of the next set of incoming rendering operations. More... | |
void | grabTexture () |
Grab the texture to a local buffer. More... | |
void | restoreTexture () |
Restore the texture from the locally buffered copy previously create by a call to grabTexture. | |
![]() | |
OpenGLTextureTarget (OpenGLRenderer &owner) | |
constructor. | |
virtual | ~OpenGLTextureTarget () |
destructor | |
bool | isImageryCache () const |
Return whether the RenderTarget is an implementation that caches actual rendered imagery. More... | |
Texture & | getTexture () const |
Return a pointer to the CEGUI::Texture that the TextureTarget is using. More... | |
bool | isRenderingInverted () const |
Return whether rendering done on the target texture is inverted in relation to regular textures. More... | |
![]() | |
OpenGLRenderTarget (OpenGLRenderer &owner) | |
Constructor. | |
void | draw (const GeometryBuffer &buffer) |
Draw geometry from the given GeometryBuffer onto the surface that this RenderTarget represents. More... | |
void | draw (const RenderQueue &queue) |
Draw geometry from the given RenderQueue onto the surface that this RenderTarget represents. More... | |
void | setArea (const Rect &area) |
Set the area for this RenderTarget. The exact action this function will take depends upon what the concrete class is representing. For example, with a 'view port' style RenderTarget, this should set the area that the view port occupies on the display (or rendering window). More... | |
const Rect & | getArea () const |
Return the area defined for this RenderTarget. More... | |
void | unprojectPoint (const GeometryBuffer &buff, const Vector2 &p_in, Vector2 &p_out) const |
Take point p_in unproject it and put the result in p_out. Resulting point is local to GeometryBuffer buff. | |
![]() | |
virtual | ~RenderTarget () |
Destructor. | |
Protected Member Functions | |
void | initialisePBuffer () |
Initialise the PBuffer with the needed size. | |
void | releasePBuffer () |
Cleans up the pbuffer resources. | |
void | enablePBuffer () const |
Switch rendering so it targets the pbuffer. | |
void | disablePBuffer () const |
Switch rendering to target what was active before the pbuffer was used. | |
void | initialiseTexture () |
Perform basic initialisation of the texture we're going to use. | |
Protected Attributes | |
int | d_pixfmt |
Holds the pixel format we use when creating the pbuffer. | |
HPBUFFERARB | d_pbuffer |
Handle to the pbuffer itself. | |
HGLRC | d_context |
Handle to the rendering context for the pbuffer. | |
HDC | d_hdc |
Handle to the Windows device context for the pbuffer. | |
HGLRC | d_prevContext |
Handle to the rendering context in use when we switched to the pbuffer. | |
HDC | d_prevDC |
Handle to the device context in use when we switched to the pbuffer. | |
![]() | |
GLuint | d_texture |
Associated OpenGL texture ID. | |
OpenGLTexture * | d_CEGUITexture |
we use this to wrap d_texture so it can be used by the core CEGUI lib. | |
![]() | |
OpenGLRenderer & | d_owner |
OpenGLRenderer that created this object. | |
Rect | d_area |
holds defined area for the RenderTarget | |
double | d_matrix [16] |
saved copy of projection matrix | |
bool | d_matrixValid |
true if saved matrix is up to date | |
double | d_viewDistance |
tracks viewing distance (this is set up at the same time as d_matrix) | |
Static Protected Attributes | |
static const float | DEFAULT_SIZE |
default size of created texture objects | |
OpenGLWGLPBTextureTarget - allows rendering to an OpenGL texture via the pbuffer WGL extension.
|
virtual |
Activate the render target and put it in a state ready to be drawn to.
Reimplemented from CEGUI::OpenGLRenderTarget.
|
virtual |
Deactivate the render target after having completed rendering.
Reimplemented from CEGUI::OpenGLRenderTarget.
|
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.
|
virtual |
Grab the texture to a local buffer.
This will destroy the OpenGL texture, and restoreTexture must be called before using it again.
Reimplemented from CEGUI::OpenGLTextureTarget.
