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

device	Pointer to the ID3D11Device interface that is to be used for CEGUI rendering operations.
context	Pointer to the ID3D11DeviceContext interface that is to be used for CEGUI rendering operations.
abi	This 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

name	String 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.

AlreadyExistsException - thrown if a Texture object named name already exists within the system.

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

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.

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.

AlreadyExistsException - thrown if a Texture object named name already exists within the system.

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

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.

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.

AlreadyExistsException - thrown if a Texture object named name already exists within the system.

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.
