◆ AddLabel()

std::shared_ptr< Label3D > open3d::visualization::gui::SceneWidget::AddLabel	(	const Eigen::Vector3f &	pos,
		const char *	text
	)

◆ ClearLabels()

void open3d::visualization::gui::SceneWidget::ClearLabels ( )

◆ DoPolygonPick()

void open3d::visualization::gui::SceneWidget::DoPolygonPick ( PolygonPickAction action )

◆ Draw()

Widget::DrawResult open3d::visualization::gui::SceneWidget::Draw ( const DrawContext & context )

overridevirtual

Draws the widget. If this is a Dear ImGUI widget, this is where the actual event processing happens. Return NONE if no action needs to be taken, REDRAW if the widget needs to be redrawn (e.g. its value changed), and RELAYOUT if the widget wishes to change size.

Reimplemented from open3d::visualization::gui::Widget.

◆ EnableSceneCaching()

void open3d::visualization::gui::SceneWidget::EnableSceneCaching ( bool enable )

Enable (or disable) caching of scene to improve UI responsiveness when dealing with large scenes (especially point clouds)

◆ ForceRedraw()

void open3d::visualization::gui::SceneWidget::ForceRedraw ( )

Forces the scene to redraw regardless of Renderer caching settings.

◆ GetCenterOfRotation()

Eigen::Vector3f open3d::visualization::gui::SceneWidget::GetCenterOfRotation ( ) const

◆ GetRenderQuality()

SceneWidget::Quality open3d::visualization::gui::SceneWidget::GetRenderQuality ( ) const

◆ GetRenderView()

rendering::View * open3d::visualization::gui::SceneWidget::GetRenderView ( ) const

◆ GetScene()

std::shared_ptr< rendering::Open3DScene > open3d::visualization::gui::SceneWidget::GetScene ( ) const

◆ GoToCameraPreset()

void open3d::visualization::gui::SceneWidget::GoToCameraPreset ( CameraPreset preset )

◆ Key()

Widget::EventResult open3d::visualization::gui::SceneWidget::Key ( const KeyEvent & e )

overridevirtual

Widgets that use Dear ImGUI should not need to override this, as Dear ImGUI will take care of all the key handling during the Draw().

Reimplemented from open3d::visualization::gui::Widget.

◆ LookAt()

void open3d::visualization::gui::SceneWidget::LookAt	(	const Eigen::Vector3f &	center,
		const Eigen::Vector3f &	eye,
		const Eigen::Vector3f &	up
	)

◆ Mouse()

Widget::EventResult open3d::visualization::gui::SceneWidget::Mouse ( const MouseEvent & e )

overridevirtual

Widgets that use Dear ImGUI should not need to override this, as Dear ImGUI will take care of all the mouse handling during the Draw().

Reimplemented from open3d::visualization::gui::Widget.

◆ RemoveLabel()

void open3d::visualization::gui::SceneWidget::RemoveLabel ( std::shared_ptr< Label3D > label )

◆ SetCenterOfRotation()

void open3d::visualization::gui::SceneWidget::SetCenterOfRotation ( const Eigen::Vector3f & center )

◆ SetFrame()

void open3d::visualization::gui::SceneWidget::SetFrame ( const Rect & f )

overridevirtual

The frame is in pixels. The size of a pixel varies on different and operating systems now frequently scale text sizes on high DPI monitors. Prefer using a Layout to using this function, but if you must use it, it is best to use a multiple of Window::GetTheme().fontSize, which represents 1em and is scaled according to the scaling factor of the window.

Reimplemented from open3d::visualization::gui::Widget.

◆ SetOnCameraChanged()

void open3d::visualization::gui::SceneWidget::SetOnCameraChanged ( std::function< void(visualization::rendering::Camera *)> on_cam_changed )

◆ SetOnPointsPicked()

void open3d::visualization::gui::SceneWidget::SetOnPointsPicked ( std::function< void(const std::map< std::string, std::vector< std::pair< size_t, Eigen::Vector3d >>> &, int)> on_picked )

◆ SetOnStartedPolygonPicking()

void open3d::visualization::gui::SceneWidget::SetOnStartedPolygonPicking ( std::function< void()> on_poly_pick )

◆ SetOnSunDirectionChanged()

void open3d::visualization::gui::SceneWidget::SetOnSunDirectionChanged ( std::function< void(const Eigen::Vector3f &)> on_dir_changed )

Enables changing the directional light with the mouse. SceneWidget will update the light's direction, so onDirChanged is only needed if other things need to be updated (like a UI).

◆ SetPickableGeometry()

void open3d::visualization::gui::SceneWidget::SetPickableGeometry ( const std::vector< PickableGeometry > & geometry )

◆ SetPickablePointSize()

void open3d::visualization::gui::SceneWidget::SetPickablePointSize ( int px )

◆ SetRenderQuality()

void open3d::visualization::gui::SceneWidget::SetRenderQuality ( Quality level )

◆ SetScene()

void open3d::visualization::gui::SceneWidget::SetScene ( std::shared_ptr< rendering::Open3DScene > scene )

◆ SetSunInteractorEnabled()

void open3d::visualization::gui::SceneWidget::SetSunInteractorEnabled ( bool enable )

◆ SetupCamera() [1/3]

void open3d::visualization::gui::SceneWidget::SetupCamera	(	const camera::PinholeCameraIntrinsic &	intrinsic,
		const Eigen::Matrix4d &	extrinsic,
		const geometry::AxisAlignedBoundingBox &	scene_bounds
	)

◆ SetupCamera() [2/3]

void open3d::visualization::gui::SceneWidget::SetupCamera	(	const Eigen::Matrix3d &	intrinsic,
		const Eigen::Matrix4d &	extrinsic,
		int	intrinsic_width_px,
		int	intrinsic_height_px,
		const geometry::AxisAlignedBoundingBox &	scene_bounds
	)

◆ SetupCamera() [3/3]

void open3d::visualization::gui::SceneWidget::SetupCamera	(	float	verticalFoV,
		const geometry::AxisAlignedBoundingBox &	scene_bounds,
		const Eigen::Vector3f &	center_of_rotation
	)

◆ SetViewControls()

void open3d::visualization::gui::SceneWidget::SetViewControls ( Controls mode )

◆ Tick()

Widget::DrawResult open3d::visualization::gui::SceneWidget::Tick ( const TickEvent & e )

overridevirtual

Tick events are sent regularly and allow for things like smoothly moving the camera based on keys that are pressed, or animations. Return DrawResult::REDRAW if you want to be redrawn.
