Member Function Documentation

static Direct3D11Renderer& CEGUI::Direct3D11Renderer::bootstrapSystem ( ID3D11Device *  device,
ID3D11DeviceContext *  context,
const int  abi = CEGUI_VERSION_ABI 
)
static

Convenience function that creates the required objects to initialise the CEGUI system.

This will create and initialise the following objects for you:
- CEGUI::Direct3D11Renderer
- CEGUI::DefaultResourceProvider
- CEGUI::System
Parameters
devicePointer to the ID3D11Device interface that is to be used for CEGUI rendering operations.
contextPointer to the ID3D11DeviceContext interface that is to be used for CEGUI rendering operations.
abiThis must be set to CEGUI_VERSION_ABI
Returns
Reference to the CEGUI::Direct3D11Renderer object that was created.
GeometryBuffer& CEGUI::Direct3D11Renderer::createGeometryBuffer ( )
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.

Returns
GeometryBuffer object.

Implements CEGUI::Renderer.

Texture& CEGUI::Direct3D11Renderer::createTexture ( const String name)
virtual

Create a 'null' Texture object.

Parameters
nameString holding the name for the new texture. Texture names must be unique within the Renderer.
Returns
A newly created Texture object. The returned Texture object has no size or imagery associated with it.

Implements CEGUI::Renderer.

Texture& CEGUI::Direct3D11Renderer::createTexture ( const String name,
const String filename,
const String resourceGroup 
)
virtual

Create a Texture object using the given image file.

Parameters
nameString holding the name for the new texture. Texture names must be unique within the Renderer.
filenameString object that specifies the path and filename of the image file to use when creating the texture.
resourceGroupString objet that specifies the resource group identifier to be passed to the resource provider when loading the texture file filename.
Returns
A newly created Texture object. The initial content of the texture memory is the requested image file.
Note
Due to possible limitations of the underlying hardware, API or engine, the final size of the texture may not match the size of the loaded file. You can check the ultimate sizes by querying the Texture object after creation.

Implements CEGUI::Renderer.

Texture& CEGUI::Direct3D11Renderer::createTexture ( const String name,
const Sizef size 
)
virtual

Create a Texture object with the given pixel dimensions as specified by size.

Parameters
nameString holding the name for the new texture. Texture names must be unique within the Renderer.
sizeSize object that describes the desired texture size.
Returns
A newly created Texture object. The initial contents of the texture memory is undefined.
Note
Due to possible limitations of the underlying hardware, API or engine, the final size of the texture may not match the requested size. You can check the ultimate sizes by querying the Texture object after creation.

Implements CEGUI::Renderer.

TextureTarget* CEGUI::Direct3D11Renderer::createTextureTarget ( )
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.
Returns
Pointer to a TextureTarget object that is suitable for caching imagery, or 0 if the renderer is unable to offer such a thing.

Implements CEGUI::Renderer.

static void CEGUI::Direct3D11Renderer::destroy ( Direct3D11Renderer renderer)
static

Destroy an Direct3D11Renderer object.

Parameters
rendererThe Direct3D11Renderer object to be destroyed.
void CEGUI::Direct3D11Renderer::destroyGeometryBuffer ( const GeometryBuffer buffer)

- CEGUI::DefaultResourceProvider
- CEGUI::Direct3D11Renderer
Note
If you did not initialise CEGUI by calling the bootstrapSystem function, you should not call this, but rather delete any objects you created manually.
void CEGUI::Direct3D11Renderer::destroyTexture ( Texture texture)
virtual

Destroy a Texture object that was previously created by calling the createTexture functions.

Parameters
textureTexture object to be destroyed.

Implements CEGUI::Renderer.

const String& CEGUI::Direct3D11Renderer::getIdentifierString ( ) const
virtual

Return identification string for the renderer module.

Returns
String object holding text that identifies the Renderer in use.

void CEGUI::Direct3D11Renderer::setDisplaySize ( const Sizef size)
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.
Note
The Renderer implementation should not use this function other than to perform internal state updates on the Renderer and related objects.
Parameters
sizeSize object describing the dimesions of the current or host window in pixels.
