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!).

◆ 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
useFixedIf 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.
fixedAxisThe 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  )

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
enabledIf 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.
targetPointer 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.
offsetIf 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

void Ogre::Camera::getWorldTransforms ( Matrix4 xform) const
overridevirtual

Gets the world transform matrix / matrices for this renderable object.

Remarks
If the object has any derived transforms, these are expected to be up to date as long as all the SceneNode structures have been updated before this is called.
This method will populate transform with 1 matrix if it does not use vertex blending. If it does use vertex blending it will fill the passed in pointer with an array of matrices, the length being the value returned from getNumWorldTransforms.
Note
Internal Ogre never supports non-affine matrix for world transform matrix/matrices, the behavior is undefined if returns non-affine matrix here.

Implements Ogre::Renderable.

◆ getMovableType()

const String& Ogre::Camera::getMovableType ( void  ) const
overridevirtual

Returns the type name of this object.

Implements Ogre::MovableObject.

◆ 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
factorThe 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,
bool  includeFarPlane = false

void Ogre::Camera::getCameraToViewportBoxVolume ( Real  screenLeft,
Real  screenTop,
Real  screenRight,
Real  screenBottom,
PlaneBoundedVolume outVolume,
bool  includeFarPlane = false

◆ 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.

◆ setUseRenderingDistance()

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