	Get value for stencil operations.

	Stencil buffer operations.

	Stencil buffer operations.

const STK::Matrix4x4f &	getTransform ()

void	setPosition (float x, float y)
	Set 2D position of the item. This method will invalidate the transform and cause it to be recalculated on the next frame.

void	setPosition (const STK::Vector2f &pos)
	Same as above.

void	setPositionX (float x)
	Set X position separately.

void	setPositionY (float y)
	Set Y position separately.

void	setScale (const STK::Vector2f &scale)

void	setScale (float scale)
	Set scale factor for the text item. This method will invalidate the transform and cause it to be recalculated on the next frame.

STK::Vector2f	getScale () const
	Returns current scale factor for the item.

void	setAngle (float angle)
	Set rotation angle for the item. Positive rotation direction is counter-clockwise. This method will invalidate the transform and cause it to be recalculated on the next frame.

float	getAngle () const

void	setTransform (const STK::Matrix4x4f &transform)
	Set transform directly. This method will set the transformation matrix for this item directly. This will override any values for setPosition(), setScale(), setDepth() and setAngle(). Also, any subsequent calls to these methods will again override this method. In short, either use setTransform() or setPosition/Scale/Angle/Depth.

Member Function Documentation

◆ cleanupBuffers()

void YardstickRenderItem::cleanupBuffers ( )

overridevirtual

Clean up OpenGL graphics objects This method should clean up all OpenGL related buffers and objects. This is normally called by GraphicsRender2D::cleanup()

Implements STK::RenderItem2D.

◆ getBatchId()

int YardstickRenderItem::getBatchId ( ) const

overridevirtual

Render batch id. This number indicates which item should be rendered together if the depths are equal.

Implements STK::RenderItem2D.

◆ getViewBoundingBox()

STK::Box2< float > YardstickRenderItem::getViewBoundingBox	(	const STK::Matrix4x4f &	mvp,
		const STK::Viewport &	glVp,
		bool	reverse_y = `false`
	)

overridevirtual

Get bounding box in viewport pixel coordinates.

Parameters

mvp	Projection/Modelview matrix.
glVp	OpenGL viewport
reverse_y	If true, any pixel coordinate calculations are using positive y direction downwards. This applies for example to text and icon items which have separate pixel coordinate transforms.

Returns: Min/Max coordinates for the object in pixel coordinates.

Implements STK::RenderItem2D.

◆ render()

void YardstickRenderItem::render	(	STK::GraphicsRender2D &	renderer,
		const STK::Matrix4x4f &	pj,
		const STK::Matrix4x4f &	vm,
		const STK::Viewport &	vp
	)

overridevirtual

Render item into the current frame. This method should render a single item into the GraphicsRender2D.

Implements STK::RenderItem2D.

◆ setRenderItem()

void Maria::YardstickRenderItem::setRenderItem ( const std::shared_ptr< GeoRenderItem > & item )

inline

This function is used to allow this render item to update its bounding box after generation.

Parameters

item	A render item
