Detailed Description

A viewpoint from which the scene will be rendered.

OGRE renders scenes from a camera viewpoint into a buffer of some sort, normally a window or a texture (a subclass of RenderTarget). OGRE cameras support both perspective projection (the default, meaning objects get smaller the further away they are) and orthographic projection (blueprint-style, no decrease in size with distance). Each camera carries with it a style of rendering, e.g. full textured, flat shaded, wireframe), field of view, rendering distances etc, allowing you to use OGRE to create complex multi-window views if required. In addition, more than one camera can point at a single render target if required, each rendering to a subset of the target, allowing split screen and picture-in-picture views.

At render time, all Scene Objects will be transformed in the camera space, which is defined as:

\(+x\) is right
\(+y\) is up
\(-z\) is away

Cameras maintain their own aspect ratios, field of view, and frustum, and project coordinates into normalised device coordinates measured from -1 to 1 in x and y, and 0 to 1 in z, where

\(+x\) is right
\(+y\) is up
\(+z\) is away

At render time, the camera will be rendering to a Viewport which will translate these parametric coordinates into real screen coordinates. Obviously it is advisable that the viewport has the same aspect ratio as the camera to avoid distortion (unless you want it!).

Constructor & Destructor Documentation

◆ Camera()

Ogre::Camera::Camera	(	const String &	name,

	)

Standard constructor.

◆ ~Camera()

virtual Ogre::Camera::~Camera ( )

virtual

Standard destructor.

Member Function Documentation

◆ addListener()

virtual void Ogre::Camera::addListener ( Listener * l )

virtual

Add a listener to this camera.

◆ getSceneManager()

SceneManager* Ogre::Camera::getSceneManager ( void ) const

Returns a pointer to the SceneManager this camera is rendering through.

◆ setPolygonMode()

void Ogre::Camera::setPolygonMode ( PolygonMode sd )

Sets the level of rendering detail required from this camera.

Remarks: Each camera is set to render at full detail by default, that is with full texturing, lighting etc. This method lets you change that behaviour, allowing you to make the camera just render a wireframe view, for example.

◆ setFixedYawAxis()

void Ogre::Camera::setFixedYawAxis	(	bool	useFixed,
		const Vector3 &	fixedAxis = `Vector3::UNIT_Y`
	)

Tells the camera whether to yaw around it's own local Y axis or a fixed axis of choice.

Remarks

This method allows you to change the yaw behaviour of the camera

by default, the camera yaws around a fixed Y axis. This is often what you want - for example if you're making a first-person shooter, you really don't want the yaw axis to reflect the local camera Y, because this would mean a different yaw axis if the player is looking upwards rather than when they are looking straight ahead. You can change this behaviour by calling this method, which you will want to do if you are making a completely free camera like the kind used in a flight simulator.

Parameters

useFixed	If `true`, the axis passed in the second parameter will always be the yaw axis no matter what the camera orientation. If false, the camera yaws around the local Y.
fixedAxis	The axis to use if the first parameter is true.

Deprecated:: attach to SceneNode and use SceneNode::yaw(angle, Node::TS_PARENT)

◆ _autoTrack()

void Ogre::Camera::_autoTrack ( void )

Internal method used by OGRE to update auto-tracking cameras.

◆ getAutoTrackTarget()

SceneNode* Ogre::Camera::getAutoTrackTarget ( void ) const

inline

Get the auto tracking target for this camera, if any.

◆ getAutoTrackOffset()

const Vector3& Ogre::Camera::getAutoTrackOffset ( void ) const

inline

Get the auto tracking offset for this camera, if it is auto tracking.

◆ setAutoTracking()

void Ogre::Camera::setAutoTracking	(	bool	enabled,
		SceneNode *const	target = `0`,
		const Vector3 &	offset = `Vector3::ZERO`
	)

Enables / disables automatic tracking of a SceneNode.

Remarks: If you enable auto-tracking, this Camera will automatically rotate to look at the target SceneNode every frame, no matter how it or SceneNode move. This is handy if you want a Camera to be focused on a single object or group of objects. Note that by default the Camera looks at the origin of the SceneNode, if you want to tweak this, e.g. if the object which is attached to this target node is quite big and you want to point the camera at a specific point on it, provide a vector in the 'offset' parameter and the camera's target point will be adjusted.

Parameters

enabled	If true, the Camera will track the SceneNode supplied as the next parameter (cannot be null). If false the camera will cease tracking and will remain in it's current orientation.
target	Pointer to the SceneNode which this Camera will track. Make sure you don't delete this SceneNode before turning off tracking (e.g. SceneManager::clearScene will delete it so be careful of this). Can be null if and only if the enabled param is false.
offset	If supplied, the camera targets this point in local space of the target node instead of the origin of the target node. Good for fine tuning the look at point.

Deprecated:: attach to SceneNode and use SceneNode::setAutoTracking

◆ setLodBias()

void Ogre::Camera::setLodBias ( Real factor = 1.0 )

Sets the level-of-detail factor for this Camera.

Remarks: This method can be used to influence the overall level of detail of the scenes rendered using this camera. Various elements of the scene have level-of-detail reductions to improve rendering speed at distance; this method allows you to hint to those elements that you would like to adjust the level of detail that they would normally use (up or down).

: The most common use for this method is to reduce the overall level of detail used for a secondary camera used for sub viewports like rear-view mirrors etc. Note that scene elements are at liberty to ignore this setting if they choose, this is merely a hint.

Parameters

factor The factor to apply to the usual level of detail calculation. Higher values increase the detail, so 2.0 doubles the normal detail and 0.5 halves it.

◆ getLodBias()

Real Ogre::Camera::getLodBias ( void ) const

Returns the level-of-detail bias factor currently applied to this camera.

Remarks: See Camera::setLodBias for more details.

◆ setLodCamera()

virtual void Ogre::Camera::setLodCamera ( const Camera * lodCam )

virtual

Set a pointer to the camera which should be used to determine LOD settings.

Remarks: Sometimes you don't want the LOD of a render to be based on the camera that's doing the rendering, you want it to be based on a different camera. A good example is when rendering shadow maps, since they will be viewed from the perspective of another camera. Therefore this method lets you associate a different camera instance to use to determine the LOD.

: To revert the camera to determining LOD based on itself, call this method with a pointer to itself.

◆ getLodCamera()

virtual const Camera* Ogre::Camera::getLodCamera ( ) const

virtual

Get a pointer to the camera which should be used to determine LOD settings.

Remarks: If setLodCamera hasn't been called with a different camera, this method will return 'this'.

		Real	screenTop,
		Real	screenRight,
		Real	screenBottom,
		PlaneBoundedVolume *	outVolume,
		bool	includeFarPlane = `false`

Notifies this camera that a viewport is using it.

◆ setAutoAspectRatio()

Parameters

frustum Pointer to a frustum to use; this can either be a manual Frustum instance (which you can attach to scene nodes like any other MovableObject), or another camera. If you pass 0 to this method it reverts the camera to normal behaviour.

◆ getViewMatrix() [2/2]

const Affine3& Ogre::Camera::getViewMatrix ( bool ownFrustumOnly ) const

Specialised version of getViewMatrix allowing caller to differentiate whether the custom culling frustum should be allowed or not.

Remarks: The default behaviour of the standard getViewMatrix is to delegate to the alternate culling frustum, if it is set. This is expected when performing CPU calculations, but the final rendering must be performed using the real view matrix in order to display the correct debug view.
