Detailed Description

Brush renderer class.

Just an interface, actual rendering will be implemented by specialized brush renderers.

Member Enumeration Documentation

enum kanzi::BrushRenderer::RenderMode

Enum signifying currently selected render mode.

Enumerator
RenderModeNone	No selection.
RenderModeInvalid	Invalid render mode - selection has been done but suitable render mode could not be selected.
RenderModeOpaqueNoContent	Opaque without content.
RenderModeTranslucentNoContent	Translucent without content.
RenderModeOpaque	Opaque with content.
RenderModeTranslucent	Translucent with content.

Constructor & Destructor Documentation

virtual kanzi::BrushRenderer::~BrushRenderer ( )

inlinevirtual

Destructor.

kanzi::BrushRenderer::BrushRenderer	(	Brush *	brush,
		Node *	node
	)

inlineexplicitprotected

Constructor.

Parameters

node	Node to attach to.
brush	Brush to attach to.

Member Function Documentation

void kanzi::BrushRenderer::updateRender	(	bool	forceOpaque,
		bool	translucencyHint
	)

Called from Node2D::updateRender(), prepare brush for rendering.

updateRender() should be called when brush material or attached nodes have been changed. Unlike bind(), updateRender() does not need to be called every frame before draw().

Parameters

forceOpaque	Should opaque render mode be selected no matter what?
translucencyHint	Additional hint to use translucent rendering.

void kanzi::BrushRenderer::updateRender ( bool forceOpaque )

inline

Default parameter override for updateRender().

Allows forcing opacity, in this situation translucency hint does not matter.

Parameters

forceOpaque Should opaque render mode be selected no matter what?

void kanzi::BrushRenderer::updateRender ( )

inline

Default parameter override for updateRender().

Opaqueness force and translucency hint are off.

void kanzi::BrushRenderer::bind ( Renderer3D & renderer )

Bind brush renderer for rendering.

Must be called before calling draw().

Parameters

renderer Renderer to use.

void kanzi::BrushRenderer::draw	(	Renderer3D &	renderer,
		const Geometry &	quad,
		const Matrix4x4 &	transform
	)		const

Draw a brush using given quad.

Parameters

renderer	Renderer to use.
quad	Quad to draw.
transform	Transform (4X4) to use.

void kanzi::BrushRenderer::draw	(	Renderer3D &	renderer,
		const Geometry &	quad,
		const Matrix3x3 &	transform
	)		const

inline

Overload for draw a brush using given quad.

Parameters

renderer	Renderer to use.
quad	Quad to draw.
transform	Transform (3X3) to use.

void kanzi::BrushRenderer::restoreResources ( )

Restore resources after sleep.

Brush* kanzi::BrushRenderer::getBrush ( ) const

inline

Access brush.

Returns: Brush pointer.

unsigned int kanzi::BrushRenderer::getPropertyChangeCounter ( ) const

inline

Access property change counter.

float kanzi::BrushRenderer::getRenderOpacity ( ) const

inline

Access opacity.

Returns: Current render opacity.

void kanzi::BrushRenderer::setRenderOpacity ( float opacity )

inline

Set opacity to use for next attach.

Parameters

opacity New render opacity.

TextureSharedPtr kanzi::BrushRenderer::getContentTexture ( ) const

inline

Access content texture.

Returns: Current content texture.

void kanzi::BrushRenderer::setContentTexture ( TextureSharedPtr texture )

inline

Set a content texture.

Parameters

texture New render texture.

Node* kanzi::BrushRenderer::getNode ( ) const

inline

Access node.

Returns: Node pointer.

RenderMode kanzi::BrushRenderer::getRenderMode ( ) const

inline

Get currently selected render mode.

Returns: Current render mode.

bool kanzi::BrushRenderer::hasRenderMode ( ) const

inline

Tell if any (valid) render mode selection has been made.

bool kanzi::BrushRenderer::hasOpaqueRenderMode ( ) const

inline

Tell if selected render mode is opaque.

virtual void kanzi::BrushRenderer::drawOverride	(	Renderer3D &	renderer,
		const Geometry &	geometry,
		const Matrix4x4 &	transform
	)		const

protectedpure virtual

Draw a clip quad.

To be implemented by specific brush implementations.

Parameters

renderer	Renderer to use.
geometry	Quad to draw.
transform	Transform to use.

Implemented in kanzi::MaterialBrushRenderer, kanzi::ColorBrushRenderer, kanzi::ContentBrushRenderer, and kanzi::TextureBrushRenderer.

virtual void kanzi::BrushRenderer::bindOverride ( Renderer3D & renderer )

protectedpure virtual

BrushRenderer-specific bind implementation.

Implemented in kanzi::MaterialBrushRenderer, kanzi::ColorBrushRenderer, kanzi::ContentBrushRenderer, and kanzi::TextureBrushRenderer.

virtual void kanzi::BrushRenderer::updateRenderOverride	(	bool	forceOpaque,
		bool	translucencyHint
	)

protectedpure virtual

BrushRenderer-specific opacity override implementation.

Parameters

forceOpaque	Should opaque render mode be selected no matter what?
translucencyHint	Additional hint to use translucent rendering.

Implemented in kanzi::MaterialBrushRenderer, kanzi::ColorBrushRenderer, kanzi::ContentBrushRenderer, and kanzi::TextureBrushRenderer.

virtual void kanzi::BrushRenderer::restoreResourcesOverride ( )

protectedpure virtual

BrushRenderer-specific restore resources implementation.

Implemented in kanzi::MaterialBrushRenderer, kanzi::ColorBrushRenderer, kanzi::ContentBrushRenderer, and kanzi::TextureBrushRenderer.

void kanzi::BrushRenderer::setRenderMode ( RenderMode selection )

inlineprotected

Set render mode.

Parameters

selection New render mode selection.

bool kanzi::BrushRenderer::isChangeCounterSame ( ) const

inlineprotected

Check if property change counter matches that of the brush.

Returns: True if matches and no update is necessary, false otherwise.

void kanzi::BrushRenderer::updateChangeCounter ( )

inlineprotected

Update property change counter to match brush.
