Detailed Description

Renderer class to interface with Microsoft DirectX 9.0.

Constructor & Destructor Documentation

CEGUI::DirectX9Renderer::DirectX9Renderer	(	LPDIRECT3DDEVICE9	device,
		uint	max_quads
	)

Constructor for Direct3D 9.0 Renderer object.

Parameters

device	Pointer to the IDirect3DDevice9 interface object that will be used for all rendering
max_quads	Obsolete. Set to 0.

Member Function Documentation

void CEGUI::DirectX9Renderer::addQuad	(	const Rect &	dest_rect,
		float	z,
		const Texture *	tex,
		const Rect &	texture_rect,
		const ColourRect &	colours,
		QuadSplitMode	quad_split_mode
	)

virtual

Add a quad to the rendering queue. All clipping and other adjustments should have been made prior to calling this.

Parameters

dest_rect	Rect object describing the destination area (values are in pixels)
z	float value specifying the z co-ordinate / z order of the quad
tex	pointer to the Texture object that holds the imagery to be rendered
texture_rect	Rect object holding the area of tex that is to be rendered (values are in texture co-ordinates).
colours	ColourRect object describing the colour values that are to be applied when rendering.
quad_split_mode	One of the QuadSplitMode values specifying the way quads are split into triangles

Returns: Nothing

Implements CEGUI::Renderer.

void CEGUI::DirectX9Renderer::clearRenderList ( void )

virtual

Clears all queued quads from the render queue.

Returns: Nothing

Implements CEGUI::Renderer.

Texture * CEGUI::DirectX9Renderer::createTexture ( void )

virtual

Creates a 'null' Texture object.

Returns: a newly created Texture object. The returned Texture object has no size or imagery associated with it, and is generally of little or no use.

Implements CEGUI::Renderer.

Texture * CEGUI::DirectX9Renderer::createTexture	(	const String &	filename,
		const String &	resourceGroup
	)

virtual

Create a Texture object using the given image file.

Parameters

filename	String object that specifies the path and filename of the image file to use when creating the texture.
resourceGroup	Resource group identifier to be passed to the resource provider when loading the texture file.

Returns: a newly created Texture object. The initial contents of the texture memory is the requested image file.

Note: Textures are always created with a size that is a power of 2. If the file you specify is of a size that is not a power of two, the final size will be rounded up. Additionally, textures are always square, so the ultimate size is governed by the larger of the width and height of the specified file. You can check the ultimate sizes by querying the texture after creation.

Implements CEGUI::Renderer.

References CEGUI::DirectX9Texture::loadFromFile().

Texture * CEGUI::DirectX9Renderer::createTexture ( float size )

virtual

Create a Texture object with the given pixel dimensions as specified by size. NB: Textures are always square.

Parameters

size	float value that specifies the size to use for the width and height when creating the new texture.

Returns: a newly created Texture object. The initial contents of the texture memory is undefined / random.

Note: Textures are always created with a size that is a power of 2. If you specify a size that is not a power of two, the final size will be rounded up. So if you specify a size of 1024, the texture will be (1024 x 1024), however, if you specify a size of 1025, the texture will be (2048 x 2048). You can check the ultimate size by querying the texture after creation.

Implements CEGUI::Renderer.

void CEGUI::DirectX9Renderer::destroyAllTextures ( void )

virtual

Destroy all Texture objects.

Returns: Nothing

Implements CEGUI::Renderer.

void CEGUI::DirectX9Renderer::destroyTexture ( Texture * texture )

virtual

Destroy the given Texture object.

Parameters

texture pointer to the Texture object to be destroyed

Returns: Nothing

Implements CEGUI::Renderer.

Referenced by destroyAllTextures().

void CEGUI::DirectX9Renderer::doRender ( void )

virtual

Perform final rendering for all quads that have been queued for rendering.

    The contents of the rendering queue is retained and can be rendered again as required.  If the contents is not required call clearRenderList().

Returns: Nothing

Implements CEGUI::Renderer.

References CEGUI::TopLeftToBottomRight.

virtual float CEGUI::DirectX9Renderer::getHeight ( void ) const

inlinevirtual

Return the current height of the display in pixels.

Returns: float value equal to the current height of the display in pixels.

Implements CEGUI::Renderer.

virtual uint CEGUI::DirectX9Renderer::getHorzScreenDPI ( void ) const

inlinevirtual

Return the horizontal display resolution dpi.

Returns: horizontal resolution of the display in dpi.

Implements CEGUI::Renderer.

virtual uint CEGUI::DirectX9Renderer::getMaxTextureSize ( void ) const

inlinevirtual

Return the maximum texture size available.

Returns: Size of the maximum supported texture in pixels (textures are always assumed to be square)

Implements CEGUI::Renderer.

virtual Rect CEGUI::DirectX9Renderer::getRect ( void ) const

inlinevirtual

Return a Rect describing the screen.

Returns: A Rect object that describes the screen area. Typically, the top-left values are always 0, and the size of the area described is equal to the screen resolution.

Implements CEGUI::Renderer.

virtual Size CEGUI::DirectX9Renderer::getSize ( void ) const

inlinevirtual

Return the size of the display in pixels.

Returns: Size object describing the dimensions of the current display.

Implements CEGUI::Renderer.

virtual uint CEGUI::DirectX9Renderer::getVertScreenDPI ( void ) const

inlinevirtual

Return the vertical display resolution dpi.

Returns: vertical resolution of the display in dpi.

Implements CEGUI::Renderer.

virtual float CEGUI::DirectX9Renderer::getWidth ( void ) const

inlinevirtual

Return the current width of the display in pixels.

Returns: float value equal to the current width of the display in pixels.

Implements CEGUI::Renderer.

virtual bool CEGUI::DirectX9Renderer::isQueueingEnabled ( void ) const

inlinevirtual

Return whether queueing is enabled.

Returns: true if queueing is enabled, false if queueing is disabled.

Implements CEGUI::Renderer.

void CEGUI::DirectX9Renderer::setDisplaySize ( const Size & sz )

Set the size of the display in pixels.

    You do not have to call this method under normal operation as the system
    will automatically extract the size from the current view port.

Note: This method will cause the EventDisplaySizeChanged event to fire if the display size has changed.

Parameters

sz	Size object describing the size of the display.

Returns: Nothing.

Referenced by postD3DReset().

virtual void CEGUI::DirectX9Renderer::setQueueingEnabled ( bool setting )

inlinevirtual

Enable or disable the queueing of quads from this point on.

    This only affects queueing.  If queueing is turned off, any calls to addQuad will cause the quad to be rendered directly.  Note that
    disabling queueing will not cause currently queued quads to be rendered, nor is the queue cleared - at any time the queue can still
    be drawn by calling doRender, and the list can be cleared by calling clearRenderList.  Re-enabling the queue causes subsequent quads
    to be added as if queueing had never been disabled.

Parameters

setting true to enable queueing, or false to disable queueing (see notes above).

Returns: Nothing

Implements CEGUI::Renderer.
