Detailed Description

Framebuffer allows the rendering to the user-specified texture or renderbuffer, instead of rendering directly to the window.

Framebuffer must have at least one Surface (Texture or Renderbuffer) attached to it. Depth and stencil tests require that a Surface (typically Renderbuffer) is attached to the depth and stencil attachment point.

Member Function Documentation

static FramebufferSharedPtr kanzi::Framebuffer::create	(	Domain *	domain,
		const CreateInfo &	createInfo,
		string_view	name
	)

static

Creates the framebuffer from specified attachments.

The framebuffer is deployed and ready to use.

Parameters

domain	Domain for the graphics resource
createInfo	Width of the framebuffer
name	Name

Returns: The created framebuffer

static FramebufferSharedPtr kanzi::Framebuffer::create	(	Domain *	domain,
		const CreateInfo &	createInfo
	)

static

Creates the framebuffer from specified attachments.

The framebuffer is deployed and ready to use.

Parameters

domain	Domain for the graphics resource
createInfo	Width of the framebuffer

Returns: The created framebuffer

SurfaceSharedPtr kanzi::Framebuffer::getAttachment ( AttachmentPoint attachment ) const

Returns the attachment from the framebuffer for the specified attachment point.

Parameters

attachment Attachment point to examine

Returns: The attachment for the specified attachment point in the framebuffer

TextureSharedPtr kanzi::Framebuffer::getTexture ( AttachmentPoint attachment ) const

Returns the attachment as texture from the framebuffer.

Parameters

attachment Attachment point to query from the framebuffer. For OpenGL ES 2, either Framebuffer::AttachmentColor0 or Framebuffer::AttachmentDepthStencil.

Returns: Texture attached to the specified attachment point, or empty if there is no texture.

unsigned int kanzi::Framebuffer::getCommonWidth ( ) const

Returns the common width of the framebuffer.

Returns: The width of the framebuffer in pixels

unsigned int kanzi::Framebuffer::getCommonHeight ( ) const

Returns the common height of the framebuffer.

Returns: The height of the framebuffer in pixels

unsigned int kanzi::Framebuffer::getCommonSampleCount ( ) const

Returns the common sample count of the framebuffer.

Returns: The number of multisample samples in the framebuffer. In OpenGL ES 2 this is zero.

Surface::Usage kanzi::Framebuffer::getUsage ( ) const

Returns Framebuffer usage.

Returns: Usage for framebuffer.

unsigned int kanzi::Framebuffer::getNativeHandle ( ) const

Returns the GL API object handle for the framebuffer.

Returns: GL API framebuffer object handle

virtual void kanzi::Framebuffer::loadFromKZB	(	const KzuResourceLoaderThreadContext *	threadContext,
		KzcInputStream *	inputStream,
		const KzuBinaryFileInfo *	file
	)

virtual

Function for loading the resource from .KZB.

This function is called when loading the data from .KZB file. Implementations should call super class loadFromKZB before reading anything else from inputStream. This function is called from arbitrary loading threads. The parameter threadContext contains thread safe memory manager and a thread specific Property manager which can be locked with the threadLock in the threadContext. This function may not access resource manager or the UIDomain due to race conditions.

Reimplemented from kanzi::Resource.

bool kanzi::Framebuffer::hasAttachment ( AttachmentPoint attachmentPoint ) const

inline

Tell if framebuffer has given attachment.

Parameters

attachment Attachment to check for.

Returns: True if yes, false if no.

virtual void kanzi::Framebuffer::invalidateOverride ( )

protectedvirtual

Notify resource that graphics context was lost and all GPU resources are invalid. Called by invalidate()

Reimplemented from kanzi::GPUResource.

virtual bool kanzi::Framebuffer::isDeployedOverride ( ) const

protectedvirtual

Implements kanzi::GPUResource.

virtual void kanzi::Framebuffer::reloadOverride ( )

protectedvirtual

Resource::reloadOverride() implementation.

Reimplemented from kanzi::Resource.
