◆ SetFollowOffset()

template<class T >

void SetFollowOffset ( const math::Vector3d & _offset )

overridevirtual

Set offset of camera from target node being followed. The offset will be in the frame that is specified at the time the follow target is set.

Parameters

[in] _offset Offset distance from target node.

Implements Camera.

◆ SetFollowPGain()

template<class T >

void SetFollowPGain ( const double _pGain )

overridevirtual

Set follow P Gain. Determines how fast the camera moves to follow the target node. Valid range: [0-1].

Parameters

[in] _pGain P gain for camera following

Implements Camera.

References gz::math::clamp().

◆ SetFollowTarget()

template<class T >

void SetFollowTarget	(	const NodePtr &	_target,
		const math::Vector3d &	_offset,
		const bool	_worldFrame
	)

overridevirtual

Set a node for camera to follow. The camera will automatically update its position to keep itself at the specified offset distance from the target being followed. If null is specified, camera follow is disabled. In contrast to SetTrackTarget, the camera does not change its orientation when following is enabled.

Parameters

[in]	_target	Target node to follow
[in]	_offset	Tether the camera at an offset distance from the target node.
[in]	_worldFrame	True to follow the target node at a distance that's fixed in world frame. Default is false which means the camera follows at fixed distance in target node's local frame.

Implements Camera.

◆ SetHFOV()

template<class T >

void SetHFOV ( const math::Angle & _hfov )

overridevirtual

Set the camera's horizontal field-of-view.

Parameters

[in] _hfov Desired horizontal field-of-view

Implements Camera.

Reimplemented in OgreCamera, and Ogre2Camera.

◆ SetImageFormat()

template<class T >

void SetImageFormat	(	PixelFormat	_format,
		bool	_reinterpretable = `false`
	)

overridevirtual

Set the image pixel format.

Parameters

[in]	_format	New image pixel format
[in]	_reinterpretable	See RenderTarget::SetFormat

Implements Camera.

References RenderTarget::SetFormat().

◆ SetImageHeight()

template<class T >

void SetImageHeight ( const unsigned int _height )

overridevirtual

Set the image height in pixels.

Parameters

[in] _height New image height in pixels

Implements Camera.

References RenderTarget::SetHeight().

template<class T >

void SetProjectionMatrix ( const math::Matrix4d & _matrix )

overridevirtual

Set the projection matrix for this camera. This overrides the standard projection matrix computed based on camera parameters.

Parameters

[in] _matrix Camera projection matrix

Implements Camera.

Reimplemented in OgreCamera, OgreDepthCamera, Ogre2BoundingBoxCamera, Ogre2Camera, Ogre2DepthCamera, Ogre2SegmentationCamera, and Ogre2ThermalCamera.

◆ SetProjectionType()

template<class T >

void SetProjectionType ( CameraProjectionType _type )

overridevirtual

Set the projection type for this camera This changes the projection matrix of the camera based on the camera projection type. A custom projection matrix can be specified via SetProjectionMatrix to override the provided one. To disable the custom projection matrix, just call this function again with the desired projection type.

Parameters

[in] _type Camera projection type

See also: SetProjectionMatrix

Implements Camera.

Reimplemented in OgreCamera, and Ogre2Camera.

◆ SetShadowsDirty()

template<class T >

void SetShadowsDirty ( )

overridevirtual

Implements Camera.

Reimplemented in Ogre2Camera, and Ogre2DepthCamera.

◆ SetTrackOffset()

template<class T >

void SetTrackOffset ( const math::Vector3d & _offset )

overridevirtual

Set track offset. Camera will track a point that's at an offset from the target node. The offset will be in the frame that is specified at the time the track target is set.

Parameters

[in] _offset Point offset to track

Implements Camera.

◆ SetTrackPGain()

template<class T >

void SetTrackPGain ( const double _pGain )

overridevirtual

Set track P Gain. Determines how fast the camera rotates to look at the target node. Valid range: [0-1].

Parameters

[in] _pGain P gain for camera tracking

Implements Camera.

References gz::math::clamp().

◆ SetTrackTarget()

template<class T >

void SetTrackTarget	(	const NodePtr &	_target,
		const math::Vector3d &	_offset,
		const bool	_worldFrame
	)

overridevirtual

Set a node for camera to track. The camera will automatically change its orientation to face the target being tracked. If null is specified, tracking is disabled. In contrast to SetFollowTarget the camera does not change its position when tracking is enabled.

Parameters

[in]	_target	Target node to track
[in]	_offset	Track a point that is at an offset relative to target.
[in]	_worldFrame	If true, the offset point to track will be treated in world frame and its position relative to the target node remains fixed regardless of the target node's rotation. Default is false, which means the camera tracks the point in target node's local frame.

Implements Camera.

◆ TrackOffset()

template<class T >

math::Vector3d TrackOffset ( ) const

overridevirtual

Get the track offset vector in the frame specified at the time the track target is set.

Returns: Point offset from target.

template<class T >

VisualPtr VisualAt ( const gz::math::Vector2i & _mousePos )

overridevirtual
