Detailed Description

A COLLADA 'look-at' transformation.

This transformation type fully defines a position and an orientation with a 3D world by using three 3D vectors: the viewer's position, the position that the viewer is looking at, and the up-vector for camera rolls.

Constructor & Destructor Documentation

FCDTLookAt::FCDTLookAt (  FCDocument *  document, FCDSceneNode *  parent )

Constructor: do not use directly. Instead, use the FCDSceneNode::AddTransform function with the transformation type: LOOKAT. Parameters: document  The COLLADA document that owns the transformation. parent  The visual scene node that contains the transformation.

Member Function Documentation

virtual FCDTransform* FCDTLookAt::Clone (  FCDTransform *  clone = NULL  )  const [virtual]

Creates a copy of a look-at transformation. Parameters: clone  The transform that will be the clone. Returns: The cloned transformation. Implements FCDTransform.

FCDAnimated* FCDTLookAt::GetAnimated (   )  [inline]

Retrieves the animated element for the transformation matrix. FCollada now supports animated look-at transforms. See also: FCDAnimatedCustom Returns: the animated element, containing 9 values. Reimplemented from FCDTransform.

FCDParameterAnimatableLookAt& FCDTLookAt::GetLookAt (   )  [inline]

Retrieves the look-at value for this transformation. Returns: The local look-at.

FMVector3& FCDTLookAt::GetPosition (   )  [inline]

Retrieves the viewer's position. Returns: The viewer's position.

FMVector3& FCDTLookAt::GetTarget (   )  [inline]

Retrieves the position that the viewer is looking at. Returns: The viewer's target.

virtual Type FCDTLookAt::GetType (   )  const [inline, virtual]

Retrieves the transformation class type for the transformation. Returns: The class type: LOOKAT. Implements FCDTransform.

FMVector3& FCDTLookAt::GetUp (   )  [inline]

Retrieves the viewer's up-vector. Returns: The up-vector.

virtual bool FCDTLookAt::IsAnimated (   )  const [virtual]

Retrieves whether the transformation is animated. FCollada now supports animated look-at transforms, through the FCDAnimatedCustom. Returns: Whether the transform is animated. Implements FCDTransform.

void FCDTLookAt::SetLookAt (  const FMLookAt &  _lookAt  )  [inline]

Sets the look-at value for this transformation. Parameters: _lookAt  A look-at.

void FCDTLookAt::SetPosition (  float  x, float  y, float  z )  [inline]

Sets the viewer's position. Parameters: x  The x-component of the position. y  The y-component of the position. z  The z-component of the position.

void FCDTLookAt::SetPosition (  const FMVector3 &  pos  )  [inline]

Sets the viewer's position. Parameters: pos  The viewer's position.

void FCDTLookAt::SetTarget (  float  x, float  y, float  z )  [inline]

Sets the position that the viewer is looking at. Parameters: x  The x-component of the target position. y  The y-component of the target position. z  The z-component of the target position.

void FCDTLookAt::SetTarget (  const FMVector3 &  target  )  [inline]

Sets the position that the viewer is looking at. Parameters: target  The target position.

void FCDTLookAt::SetUp (  float  x, float  y, float  z )  [inline]

Sets the viewer's up-vector. Parameters: x  The x-component of the up-vector. y  The y-component of the up-vector. z  The z-component of the up-vector.

void FCDTLookAt::SetUp (  const FMVector3 &  up  )  [inline]

Sets the viewer's up-vector. Parameters: up  The up-vector.

virtual FMMatrix44 FCDTLookAt::ToMatrix (   )  const [virtual]

Converts the transformation into a matrix. Returns: The transformation matrix. Implements FCDTransform.
