Detailed Description

This class is the base class for all perspective views.

Constructor & Destructor Documentation

◆ PerspectiveView()

Ocean::Rendering::PerspectiveView::PerspectiveView ( )
protected

Creates a new perspective view object.

◆ ~PerspectiveView()

Ocean::Rendering::PerspectiveView::~PerspectiveView ( )
overrideprotected

Destructs a perspective view object.

Member Function Documentation

◆ fitCamera()

void Ocean::Rendering::PerspectiveView::fitCamera ( const NodeRef node = NodeRef())
overridevirtual

Fits the camera to a given node.

See also
View::fitCamera().

Reimplemented from Ocean::Rendering::View.

◆ fovX()

virtual Scalar Ocean::Rendering::PerspectiveView::fovX ( ) const
virtual

Returns the horizontal field of view in radian.

Returns
Horizontal field of view in radian, with range (0, PI)
Exceptions
NotSupportedExceptionIs thrown if this function is not supported

Reimplemented in Ocean::Rendering::GlobalIllumination::GIPerspectiveView, and Ocean::Rendering::GLESceneGraph::GLESPerspectiveView.

◆ idealFovX()

virtual Scalar Ocean::Rendering::PerspectiveView::idealFovX ( bool *  validCamera = nullptr) const
virtual

Calculates the ideal field of view matching to the current background.

If the background holds a medium and no valid frame has been provided by this medium jet this function will return the view's field of view.

Parameters
validCameraOptional resulting state determining whether the background had a valid camera object
Returns
Resulting field of view in radian

◆ setFovX()

virtual bool Ocean::Rendering::PerspectiveView::setFovX ( const Scalar  fovx)
virtual

Sets the horizontal field of view in radian.

Parameters
fovxHorizontal field of view in radian, with range (0, PI)
Returns
True, if the value is valid and could be set
Exceptions
NotSupportedExceptionIs thrown if this function is not supported

Reimplemented in Ocean::Rendering::GlobalIllumination::GIPerspectiveView, and Ocean::Rendering::GLESceneGraph::GLESPerspectiveView.

◆ setProjectionMatrix()

virtual void Ocean::Rendering::PerspectiveView::setProjectionMatrix ( const SquareMatrix4 clip_T_view)
virtual

Sets the projection matrix explicitly.

Parameters
clip_T_viewThe projection matrix to set
Exceptions
NotSupportedExceptionIs thrown if this function is not supported

Reimplemented in Ocean::Rendering::GLESceneGraph::GLESPerspectiveView.

◆ type()

ObjectType Ocean::Rendering::PerspectiveView::type ( ) const
overridevirtual

Returns the type of this object.

See also
Object::type().

Reimplemented from Ocean::Rendering::Object.

Reimplemented in Ocean::Rendering::StereoView.

◆ updateToIdealFovX()

virtual void Ocean::Rendering::PerspectiveView::updateToIdealFovX ( )
virtual

Updates the view's field of view to the ideal field of view matching with the current background.
