Detailed Description

Brush renderer class.

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

enum kanzi::BrushRenderer::RenderMode

Enum signifying currently selected render mode.

Enumerator

RenderModeNone

No selection.

RenderModeContent

Content specified for brush.

Since: Kanzi 3.9.1

RenderModeNoContent

No content specified for brush.

Since: Kanzi 3.9.1

Constructor & Destructor Documentation

◆ ~BrushRenderer()

virtual kanzi::BrushRenderer::~BrushRenderer ( )

virtualdefault

Destructor.

◆ BrushRenderer()

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

explicitprotected

Constructor.

Parameters

node	The node to which to attach.
brush	The brush to which to attach.

Member Function Documentation

◆ updateRender()

void kanzi::BrushRenderer::updateRender	(	optional< int >	blendMode,
		bool	forceOpaque,
		bool	translucencyHint
	)

inline

Called from Node2D::updateRender().

Prepares a brush for rendering. Call this function when the brush material or attached nodes have changed. Unlike bind(), updateRender() does not need to be called every frame before draw().

Parameters

blendMode	Optional blend mode override.
forceOpaque	Whether to select the opaque render mode in any case.
translucencyHint	Additional hint to use translucent rendering.

Since: Kanzi 3.9.1 added blendMode parameter.

◆ bind()

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

inline

Bind brush renderer for rendering.

Must be called before calling draw().

Parameters

renderer Renderer to use.

◆ draw() [1/2]

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

Draw a brush using given quad.

Parameters

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

◆ draw() [2/2]

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

inline

Overload for draw a brush using given quad.

Parameters

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

◆ restoreResources()

void kanzi::BrushRenderer::restoreResources ( )

inline

Restore resources after sleep.

◆ getBrush()

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

inline

Access brush.

Returns: Brush pointer.

◆ getPropertyChangeCounter()

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

inline

Access property change counter.

◆ getRenderOpacity()

float kanzi::BrushRenderer::getRenderOpacity ( ) const

inline

Access opacity.

Returns: Current render opacity.

◆ setRenderOpacity()

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

inline

Set opacity to use for next attach.

Parameters

opacity New render opacity.

◆ getContentTexture()

TextureSharedPtr kanzi::BrushRenderer::getContentTexture ( ) const

inline

Access content texture.

Returns: Current content texture.

◆ setContentTexture()

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

inline

Set a content texture.

Parameters

texture New render texture.

◆ getNode()

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

inline

Gets the attached node.

Returns: Node pointer.

◆ getRenderMode()

RenderMode kanzi::BrushRenderer::getRenderMode ( ) const

inline

Get currently selected render mode.

Returns: Current render mode.

◆ hasRenderMode()

bool kanzi::BrushRenderer::hasRenderMode ( ) const

inline

Indicates whether a valid render mode is selected.

Returns: If a render mode has been selected, true, otherwise false.

◆ getMaterial()

virtual MaterialSharedPtr kanzi::BrushRenderer::getMaterial ( )

inlinevirtual

Get currently set material for the renderer.

Returns: Shared pointer to the material that is currently set for the brush renderer. If not set, returns nullptr.

Reimplemented in kanzi::MaterialBrushRenderer, and kanzi::ContentBrushRenderer.

◆ getBlendModeValue()

int kanzi::BrushRenderer::getBlendModeValue ( )

inline

Gets the last used blend mode value.

This function is intended for tests.

Returns: Blend mode.

Since: Kanzi 3.9.1

◆ drawOverride()
