	Returns current scale factor for the item.

Member Function Documentation

◆ cleanupBuffers()

void STK::EllipseRender2D::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.

◆ drawVertexArrays()

void STK::EllipseRender2D::drawVertexArrays ( )

inline

Draw vertex buffers. Low level rendering of the vertex buffers. Needs the correct shader and uniforms to be set first. This method is normally called by the GraphicsRender2D class.

◆ getBatchId()

int STK::EllipseRender2D::getBatchId ( ) const

overridevirtual

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

Implements STK::RenderItem2D.

◆ getFixedSize()

bool STK::EllipseRender2D::getFixedSize ( ) const

inline

See also: setFixedSize()

◆ getViewBoundingBox()

STK::Box2< float > STK::EllipseRender2D::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 STK::EllipseRender2D::render	(	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.

◆ setFixedSize()

void STK::EllipseRender2D::setFixedSize ( bool fixed )

inline

Set object to be fixed size (in pixels). If true, any viewport scaling will not affect the geometry of this object. All transforms that are set explicitly on the object through INativeRenderItem2D (Position, Scale, Rotation) will still be applied. Example: A circle with offset c = (10, 20) and r = 30 pixels will always be rendered with 30 pixels radius at (10, 20) pixels offset from Position, but can still be moved by changing the Position vector.
