Public Member Functions | |
bool | isTexCoordSystemFlipped () const |
Returns if the texture coordinate system is vertically flipped or not. The original of a texture coordinate system is typically located either at the the top-left or the bottom-left. CEGUI, Direct3D and most rendering engines assume it to be on the top-left. OpenGL assumes it to be at the bottom left. More... | |
RenderTarget & | getDefaultRenderTarget () |
Returns the default RenderTarget object. The default render target is is typically one that targets the entire screen (or rendering window). More... | |

Convenience function that creates all the necessary objects then initialises the CEGUI system with them.
This will create and initialise the following objects for you:
abi | This must be set to CEGUI_VERSION_ABI |
|
virtual |
Create a new GeometryBuffer and return a reference to it. You should remove the GeometryBuffer from any RenderQueues and call destroyGeometryBuffer when you want to destroy the GeometryBuffer.
Implements CEGUI::Renderer.
Create a 'null' Texture object.
name | String holding the name for the new texture. Texture names must be unique within the Renderer. |
Implements CEGUI::Renderer.
|
virtual |
Create a Texture object using the given image file.
name | String holding the name for the new texture. Texture names must be unique within the Renderer. |
filename | String object that specifies the path and filename of the image file to use when creating the texture. |
resourceGroup | String objet that specifies the resource group identifier to be passed to the resource provider when loading the texture file filename. |
Implements CEGUI::Renderer.
Create a Texture object with the given pixel dimensions as specified by size.
name | String holding the name for the new texture. Texture names must be unique within the Renderer. |
size | Size object that describes the desired texture size. |
Implements CEGUI::Renderer.
|
virtual |
Create a TextureTarget that can be used to cache imagery; this is a RenderTarget that does not lose it's content from one frame to another.
If the renderer is unable to offer such a thing, 0 should be returned.
Implements CEGUI::Renderer.
|
virtual |
Destroy a GeometryBuffer that was returned when calling the createGeometryBuffer function. Before destroying any GeometryBuffer you should ensure that it has been removed from any RenderQueue that was using it.
buffer | The GeometryBuffer object to be destroyed. |
Implements CEGUI::Renderer.
|
static |
Convenience function to cleanup the CEGUI system and related objects that were created by calling the bootstrapSystem function.
This function will destroy the following objects for you:
|
virtual |
Destroy a Texture object that was previously created by calling the createTexture functions.
texture | Texture object to be destroyed. |
Implements CEGUI::Renderer.
|
virtual |
Destroy a Texture object that was previously created by calling the createTexture functions.
name | String holding the name of the texture to destroy. |
Implements CEGUI::Renderer.
|
virtual |
Function that cleans up TextureTarget objects created with the createTextureTarget function.
target | A pointer to a TextureTarget object that was previously returned from a call to createTextureTarget. |
Implements CEGUI::Renderer.
|
virtual |
Returns the default RenderTarget object. The default render target is is typically one that targets the entire screen (or rendering window).
Implements CEGUI::Renderer.
|
virtual |
Return the resolution of the display or host window in dots per inch.
Implements CEGUI::Renderer.
|
virtual |
Return the size of the display or host window in pixels.
Implements CEGUI::Renderer.
|
virtual |
Return identification string for the renderer module.
Implements CEGUI::Renderer.
|
virtual |
Return the pixel size of the maximum supported texture.
Implements CEGUI::Renderer.
Return a Texture object that was previously created by calling the createTexture functions.
Implements CEGUI::Renderer.
|
inline |
Returns if the texture coordinate system is vertically flipped or not. The original of a texture coordinate system is typically located either at the the top-left or the bottom-left. CEGUI, Direct3D and most rendering engines assume it to be on the top-left. OpenGL assumes it to be at the bottom left.
This function is intended to be used when generating geometry for rendering the TextureTarget onto another surface. It is also intended to be used when trying to use a custom texture (RTT) inside CEGUI using the Image class, in order to determine the Image coordinates correctly.
|
virtual |
Set the size of the display or host window in pixels for this Renderer object.
This is intended to be called by the System as part of the notification process when display size changes are notified to it via the System::notifyDisplaySizeChanged function.
size | Size object describing the dimesions of the current or host window in pixels. |
Implements CEGUI::Renderer.
