Detailed Description

A viewpoint from which the scene will be rendered.

Remarks: 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.

: Cameras maintain their own aspect ratios, field of view, and frustum, and project co-ordinates into a space measured from -1 to 1 in x and y, and 0 to 1 in z. At render time, the camera will be rendering to a Viewport which will translate these parametric co-ordinates into real screen co-ordinates. Obviously it is advisable that the viewport has the same aspect ratio as the camera to avoid distortion (unless you want it!).

: Starting Ogre 2.x, a Camera must be attached to a SceneNode, using the method SceneNode::attachObject. By default the camera is attached to the root scene node on creation. When this is done the Camera will combine it's own position/orientation settings with it's parent SceneNode. This is also useful for implementing more complex Camera / object relationships i.e. having a camera attached to a world object.

Member Enumeration Documentation

◆ CameraSortMode

enum Ogre::Camera::CameraSortMode

Sets how the objects are sorted.

This affects both opaque (performance optimization, rendered front to back) and transparents (visual correctness, rendered back to front)

Object sorting is approximate, and some scenes are suited to different modes depending on the objects' geometric properties

See https://forums.ogre3d.org/viewtopic.php?f=2&t=94090 for examples

Please note that RenderQueue::addRenderable quantizes the final depth value. Therefore if two objects are numerically very close, the chosen mode may not make too much of a difference.

Enumerator
SortModeDistance	Sort objects by distance to camera. i.e. cameraPos.distance( objPos ) - objRadius The bigger the object radius, the closer it is considered to be to the camera
SortModeDepth	Sort objects by depth i.e. objViewSpacePos.z - objRadius The bigger the object radius, the closer it is considered to be to the camera
SortModeDistanceRadiusIgnoring	Same as SortModeDistance, but skips object radius from calculations.
SortModeDepthRadiusIgnoring	Same as SortModeDepth, but skips object radius from calculations.

◆ lookAt() [2/2]

void Ogre::Camera::lookAt	(	Real	x,
		Real	y,
		Real	z
	)

Points the camera at a location in worldspace.

◆ removeListener()

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

virtual

Remove a listener to this camera.

◆ resetWindow()

		const Radian &	angle
	)

Rotate the camera around an arbitrary axis.

◆ setAutoAspectRatio()

void Ogre::Camera::setAutoAspectRatio ( bool autoratio )

If set to true a viewport that owns this frustum will be able to recalculate the aspect ratio whenever the frustum is resized.

Remarks: You should set this to true only if the frustum / camera is used by one viewport at the same time. Otherwise the aspect ratio for other viewports may be wrong.

◆ 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.

◆ setCullingFrustum()

void Ogre::Camera::setCullingFrustum ( Frustum * frustum )

inline

Tells the camera to use a separate Frustum instance to perform culling.

Remarks: By calling this method, you can tell the camera to perform culling against a different frustum to it's own. This is mostly useful for debug cameras that allow you to show the culling behaviour of another camera, or a manual frustum instance.

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.

◆ setDefaultSortMode()

static void Ogre::Camera::setDefaultSortMode ( CameraSortMode sortMode )

inlinestatic

Sets the default sort mode for all future Camera instances.

◆ setDirection() [1/2]

void Ogre::Camera::setDirection ( const Vector3 & vec )

Sets the camera's direction vector.

◆ setDirection() [2/2]

void Ogre::Camera::setDirection	(	Real	x,
		Real	y,
		Real	z
	)

Sets the camera's direction vector.

Remarks: Note that the 'up' vector for the camera will automatically be recalculated based on the current 'up' vector (i.e. the roll will remain the same).

◆ 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.

◆ setLightCullingVisibility()

void Ogre::Camera::setLightCullingVisibility	(	bool	collectLights,
		bool	isCubemap
	)

When a camera is created via SceneManager::createCamera, there are two additional parameters.

Parameters

collectLights	Tell Ogre to cull lights against this camera. This requires additional CPU power. If a camera is not going to be used for a long time (or it doesn't need lights, which is what happens with shadow mapping cameras) you want this set to false. Otherwise if you need to render and need lights, enable this setting.
isCubemap	Use an alternative algorithm to collect lights in 360° around the camera. This is required if the camera is going to be used in passes where CompositorPassSceneDef::mCameraCubemapReorient = true; Does nothing if collectLights = false

◆ 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.

◆ 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.

◆ setOrientation()

void Ogre::Camera::setOrientation ( const Quaternion & q )

Sets the camera's orientation.

◆ setPosition() [1/2]

void Ogre::Camera::setPosition ( const Vector3 & vec )

Sets the camera's position.

◆ setPosition() [2/2]

void Ogre::Camera::setPosition	(	Real	x,
		Real	y,
		Real	z
	)

Sets the camera's position.

◆ setUseMinPixelSize()

void Ogre::Camera::setUseMinPixelSize ( bool enable )

inline

Sets whether to use min display size calculations.

When active, objects that derive from MovableObject whose size on the screen is less then a MovableObject::mMinPixelSize will not be rendered.

◆ setUseRenderingDistance()

virtual void Ogre::Camera::setUseRenderingDistance ( bool use )

inlinevirtual

Set whether this camera should use the 'rendering distance' on objects to exclude distant objects from the final image.

The default behaviour is to use it.

Parameters

use	True to use the rendering distance, false not to.

◆ setVrData()

void Ogre::Camera::setVrData ( VrData * vrData )

Sets VR data for calculating left & right eyes See OpenVR sample for more info.

Parameters

vrData Pointer to valid VrData This pointer must remain valid while the Camera is using it. We won't free this pointer. It is the developer's responsability to free it once no longer in use. Multiple cameras can share the same VrData pointer. The internal data hold by VrData can be changed withohut having to call setVrData again

◆ setWindow()

virtual void Ogre::Camera::setWindow	(	Real	left,
		Real	top,
		Real	right,
		Real	bottom
	)

virtual

Sets the viewing window inside of viewport.

Remarks: This method can be used to set a subset of the viewport as the rendering target.

Parameters

left	Relative to Viewport - 0 corresponds to left edge, 1 - to right edge (default - 0).
top	Relative to Viewport - 0 corresponds to top edge, 1 - to bottom edge (default - 0).
right	Relative to Viewport - 0 corresponds to left edge, 1 - to right edge (default - 1).
bottom	Relative to Viewport - 0 corresponds to top edge, 1 - to bottom edge (default - 1).

◆ synchroniseBaseSettingsWith()

virtual void Ogre::Camera::synchroniseBaseSettingsWith ( const Camera * cam )

virtual

Synchronise core camera settings with another.

Remarks: Copies the position, orientation, clip distances, projection type, FOV, focal length and aspect ratio from another camera. Other settings like query flags, reflection etc are preserved.

◆ yaw()

void Ogre::Camera::yaw ( const Radian & angle )

Rotates the camera anticlockwise around it's local y axis.
