Detailed Description

Composition target.

Collection of different elements managed by the composition manager.

Constructor & Destructor Documentation

Target() [1/3]

kanzi::CompositionManager::Target::Target ( )

inlineexplicit

Empty constructor.

Target created in this way is not valid.

Target() [2/3]

kanzi::CompositionManager::Target::Target ( TextureSharedPtr texture )

inlineexplicit

Constructor.

Only texture is defined.

Target() [3/3]

kanzi::CompositionManager::Target::Target ( TextureSharedPtr texture, RenderbufferSharedPtr colorRenderBuffer, TextureSharedPtr depthTexture )

inlineexplicit

Constructor.

Specify all components and reattach framebuffers.

Parameters

texture	Main texture.
colorRenderBuffer	Color render buffer.
depthTexture	Depth texture.

Member Function Documentation

getTexture()

TextureSharedPtr kanzi::CompositionManager::Target::getTexture ( ) const

inline

Gets the main texture.

Main texture may exist even if its graphics format is GraphicsFormatNone.

Returns

Shared pointer to color texture or nullptr if color texture is not set.

setColorTexture()

void kanzi::CompositionManager::Target::setColorTexture ( TextureSharedPtr colorTexture )

inline

Sets the color texture.

Kanzi uses this function internally. You do not need to manually modify the composition targets.

Parameters

colorTexture

Color texture to set.

getColorRenderbuffer()

RenderbufferSharedPtr kanzi::CompositionManager::Target::getColorRenderbuffer ( ) const

inline

Gets the color renderbuffer.

Returns

Shared pointer to renderbuffer. May be empty.

getDepthStencilRenderbuffer()

RenderbufferSharedPtr kanzi::CompositionManager::Target::getDepthStencilRenderbuffer ( ) const

inline

Gets the depth/stencil renderbuffer.

Returns

Shared pointer to depth/stencil renderbuffer or nullptr.

getDepthTexture()

TextureSharedPtr kanzi::CompositionManager::Target::getDepthTexture ( ) const

inline

Gets the depth texture.

Returns

Shared pointer to depth texture or nullptr if depth texture is not set.

setDepthTexture()

void kanzi::CompositionManager::Target::setDepthTexture ( TextureSharedPtr depthTexture )

inline

Sets the depth texture.

Kanzi uses this function internally. You do not need to manually modify the composition targets.

Parameters

depthTexture

Depth texture to set.

getWidth()

unsigned int kanzi::CompositionManager::Target::getWidth ( ) const

inline

Gets the width of the texture that has the framebuffer.

Returns

Composition target width.

getHeight()

unsigned int kanzi::CompositionManager::Target::getHeight ( ) const

inline

Gets the height of the texture that has the framebuffer.

Returns

Composition target height.

getSampleCount()

unsigned int kanzi::CompositionManager::Target::getSampleCount ( ) const

inline

Gets the sample count for the composition target.

This is either the sample count for the texture with the framebuffer or for the color render buffer.

Returns

Sample count as unsigned integer. Values <= 1 mean multisampling is disabled.

getAddressingMode()

Sampler::AddressingMode kanzi::CompositionManager::Target::getAddressingMode ( ) const

inline

Gets the addressing mode of the composition target.

All textures in the composition target have the same sampling mode.

Returns

Addressing mode.

getFilterMode()

Sampler::Filter kanzi::CompositionManager::Target::getFilterMode ( ) const

inline

Gets the filter mode of the composition target.

All textures in the composition target have the same filter mode.

Returns

Filter mode.

getMipmapMode()

Sampler::MipmapMode kanzi::CompositionManager::Target::getMipmapMode ( ) const

inline

Gets the mipmap mode of the composition target.

All textures in the composition target have the same mipmap mode.

Returns

Mipmap mode.

getColorFormat()

GraphicsFormat kanzi::CompositionManager::Target::getColorFormat ( ) const

inline

Gets the color format.

This is either the color format of the color render buffer, or that of the texture.

Returns

Graphics format. May be GraphicsFormatNone if only depth texture has meaning.

getDepthStencilFormat()

GraphicsFormat kanzi::CompositionManager::Target::getDepthStencilFormat ( ) const

inline

Gets the depth and/or stencil format.

Depth and/or stencil format is combined from the format of the texture and potentially of the depth texture.

Returns

Graphics format.

getCompositionTexture()

TextureSharedPtr kanzi::CompositionManager::Target::getCompositionTexture ( ) const

inline

Gets the texture used for composition.

Returns

Shared pointer to texture.

getResolveSettings()

tuple< TextureSharedPtr, bool, bool > kanzi::CompositionManager::Target::getResolveSettings ( ) const

inline

Get the information for resolve target.

Returns

Triplet of resolve framebuffer and boolean flags for whether color and depth are resolved.

getAttachmentPointTexture()

TextureSharedPtr kanzi::CompositionManager::Target::getAttachmentPointTexture ( FramebufferAttachmentPoint attachmentPoint ) const

inline

Gets the texture corresponding to a given attachment point.

Parameters

attachmentPoint

Attachment point to get.

Returns

Shared pointer to texture or an empty shared pointer if no corresponding attachment point.

generateMipmaps()

void kanzi::CompositionManager::Target::generateMipmaps ( )

inline

Generate mipmaps for all textures in the composition target.

reset()

void kanzi::CompositionManager::Target::reset ( )

inline

Clear all memory used by the composition target.

operator bool_type()

kanzi::CompositionManager::Target::operator bool_type ( ) const

inline
