◆ SetAntiAliasing()

virtual void SetAntiAliasing ( const unsigned int  _aa)
overridevirtual

Set the level of anti-aliasing used during rendering. If a value of 0 is given, no anti-aliasing will be performed. Higher values can significantly slow-down rendering times, depending on the underlying render engine.

Parameters
[in]_aaLevel of anti-aliasing used during rendering

Reimplemented from BaseCamera< OgreSensor >.

◆ SetAspectRatio()

virtual void SetAspectRatio ( const double  _ratio)
overridevirtual

Set the camera's aspect ratio. This value determines the cameras vertical field-of-view. It is often the.

image_height /
image_width

but this is not necessarily true.

Setting a value <= 0.0 indicates the aspect ratio will be automatically calculated based on width & height.

Returns
The camera's aspect ratio

Reimplemented from BaseCamera< OgreSensor >.

◆ SetBackgroundColor()

virtual void SetBackgroundColor ( const math::Color _color)
virtual

◆ SetFarClipPlane()

virtual void SetFarClipPlane ( const double  _far)
overridevirtual

Set the camera's far clipping plane distance.

Parameters
[in]_farFar clipping plane distance

Reimplemented from BaseCamera< OgreSensor >.

◆ SetHFOV()

virtual void SetHFOV ( const math::Angle _hfov)
overridevirtual

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

Parameters
[in]_hfovDesired horizontal field-of-view

Reimplemented from BaseCamera< OgreSensor >.

◆ SetMaterial()

virtual void SetMaterial ( const MaterialPtr _material)
overridevirtual

Set a material that the camera should see on all objects.

Parameters
[in]_materiala material instance

Reimplemented from BaseCamera< OgreSensor >.

◆ SetNearClipPlane()

virtual void SetNearClipPlane ( const double  _near)
overridevirtual

Set the camera's near clipping plane distance.

Parameters
[in]_nearNear clipping plane distance

Reimplemented from BaseCamera< OgreSensor >.

◆ SetProjectionMatrix()

virtual 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]_matrixCamera projection matrix

Reimplemented from BaseCamera< OgreSensor >.

◆ SetProjectionType()

virtual 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]_typeCamera projection type

virtual void SetSelectionBuffer ( )
protectedvirtual

◆ SetVFOV()

void SetVFOV ( double  cameraVFOV) const

◆ SetVisibilityMask()

virtual void SetVisibilityMask ( uint32_t  _mask)
overridevirtual

Set visibility mask.

Parameters
[in]_maskVisibility mask

Implements Sensor.

◆ SyncOgreCameraAspectRatio()

void SyncOgreCameraAspectRatio ( )
protected

Synchronizes every setting that depends on AspectRatio with Ogre's camera.

◆ ViewMatrix()

virtual math::Matrix4d ViewMatrix ( ) const
overridevirtual

Get the view matrix for this camera.

Returns
Camera view matrix

Implements Camera.

◆ VisualAt()

virtual VisualPtr VisualAt ( const gz::math::Vector2i _mousePos)
overridevirtual

Get the visual for a given mouse position param[in] _mousePos mouse position.
