Detailed Description

Allows the rendering of a simple 2D rectangle This class renders a simple 2D rectangle; this rectangle has no depth and therefore is best used with 'depth_write off' materials.

: Beginning Ogre 2.0, it supports building a full screen triangle instead of rectangle. Position & UVs are in the first source. Normals are in the second one

Member Function Documentation

◆ _releaseManualHardwareResources()

void Ogre::v1::Rectangle2D::_releaseManualHardwareResources ( )

overridevirtual

Notifies the movable object that hardware resources were lost.

Remarks: Called automatically by RenderSystem if hardware resources were lost and can not be restored using some internal mechanism. Among affected resources are nested shadow renderables, ManualObjects, etc.

Reimplemented from Ogre::MovableObject.

◆ _restoreManualHardwareResources()

void Ogre::v1::Rectangle2D::_restoreManualHardwareResources ( )

overridevirtual

Notifies the movable object that hardware resources should be restored.

Remarks: Called automatically by RenderSystem if hardware resources were lost and can not be restored using some internal mechanism. Among affected resources are nested shadow renderables, ManualObjects, etc.

Reimplemented from Ogre::MovableObject.

◆ getLights()

const LightList& Ogre::v1::Rectangle2D::getLights ( ) const

overridevirtual

Gets a list of lights, ordered relative to how close they are to this renderable.

Remarks: Directional lights, which have no position, will always be first on this list.

Implements Ogre::Renderable.

◆ getMovableType()

const String& Ogre::v1::Rectangle2D::getMovableType ( ) const

overridevirtual

Returns the type name of this object.

Implements Ogre::MovableObject.

◆ getRenderOperation()

void Ogre::v1::Rectangle2D::getRenderOperation	(	RenderOperation &	op,
		bool	casterPass
	)

overridevirtual

Gets the render operation required to send this object to the frame buffer.

Implements Ogre::Renderable.

◆ getSquaredViewDepth()

Real Ogre::v1::Rectangle2D::getSquaredViewDepth ( const Camera * cam ) const

inline

◆ getWorldTransforms()

void Ogre::v1::Rectangle2D::getWorldTransforms ( Matrix4 * xform ) const

overridevirtual

Gets the world transform matrix / matrices for this renderable object.

Remarks: If the object has any derived transforms, these are expected to be up to date as long as all the SceneNode structures have been updated before this is called.

: This method will populate transform with 1 matrix if it does not use vertex blending. If it does use vertex blending it will fill the passed in pointer with an array of matrices, the length being the value returned from getNumWorldTransforms.

Note: Internal Ogre never supports non-affine matrix for world transform matrix/matrices, the behavior is undefined if returns non-affine matrix here.

See also: Matrix4::isAffine.

Implements Ogre::Renderable.

◆ setCorners()

void Ogre::v1::Rectangle2D::setCorners	(	Real	left,
		Real	top,
		Real	width,
		Real	height
	)

Sets the corners of the rectangle, in relative coordinates.

Parameters

left	Left position in screen normalized coordinates, 0 = left edge, 1 = right edge
top	Top position in screen normalized coordinates, 0 = top edge, 1 = bottom edge
width	Width in screen normalized coordinates
height	Height in screen normalized coordinates

◆ setNormals()

void Ogre::v1::Rectangle2D::setNormals	(	const Ogre::Vector3 &	topLeft,
		const Ogre::Vector3 &	bottomLeft,
		const Ogre::Vector3 &	topRight,
		const Ogre::Vector3 &	bottomRight
	)

Sets the normals of the rectangle.

Remarks: Be careful the normals can be bilinearly interpolated correctly, otherwise the results between Fullscreen Triangles & Fullscreen Quads will be different
