Detailed Description

Abstract class defining the basic required interface for Renderer objects.

Objects derived from Renderer are the means by which the GUI system interfaces with specific rendering technologies. To use a rendering system or API to draw CEGUI imagery requires that an appropriate Renderer object be available.


Member Function Documentation

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.

Implemented in CEGUI::OgreRenderer, CEGUI::OpenGLESRenderer, CEGUI::Direct3D11Renderer, CEGUI::IrrlichtRenderer, CEGUI::Direct3D9Renderer, CEGUI::Direct3D10Renderer, CEGUI::NullRenderer, CEGUI::OpenGLRendererBase, and CEGUI::DirectFBRenderer.

virtual Texture& CEGUI::Renderer::createTexture ( const String name) [pure 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.

Implemented in CEGUI::OgreRenderer, CEGUI::OpenGLESRenderer, CEGUI::Direct3D11Renderer, CEGUI::IrrlichtRenderer, CEGUI::Direct3D9Renderer, CEGUI::Direct3D10Renderer, CEGUI::NullRenderer, CEGUI::OpenGLRendererBase, and CEGUI::DirectFBRenderer.

virtual Texture& CEGUI::Renderer::createTexture ( const String name,
const String filename,
const String resourceGroup 
) [pure 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.

Implemented in CEGUI::OgreRenderer, CEGUI::OpenGLESRenderer, CEGUI::Direct3D11Renderer, CEGUI::IrrlichtRenderer, CEGUI::Direct3D9Renderer, CEGUI::Direct3D10Renderer, CEGUI::NullRenderer, CEGUI::OpenGLRendererBase, and CEGUI::DirectFBRenderer.

virtual Texture& CEGUI::Renderer::createTexture ( const String name,
const Sizef size 
) [pure 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.

Implemented in CEGUI::OgreRenderer, CEGUI::OpenGLESRenderer, CEGUI::Direct3D11Renderer, CEGUI::IrrlichtRenderer, CEGUI::Direct3D9Renderer, CEGUI::Direct3D10Renderer, CEGUI::NullRenderer, CEGUI::OpenGLRendererBase, and CEGUI::DirectFBRenderer.

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.

Implemented in CEGUI::OgreRenderer, CEGUI::OpenGLESRenderer, CEGUI::Direct3D11Renderer, CEGUI::IrrlichtRenderer, CEGUI::Direct3D9Renderer, CEGUI::Direct3D10Renderer, CEGUI::NullRenderer, CEGUI::OpenGLRendererBase, and CEGUI::DirectFBRenderer.

virtual void CEGUI::Renderer::destroyGeometryBuffer ( const GeometryBuffer buffer) [pure virtual]
