Detailed Description

The lookat element contains a position and orientation transformation suitable for aiming a camera.

Positioning and orienting a camera or object in the scene is often complicated when using a matrix. A lookat transform is an intuitive way to specify an eye position, interest point, and orientation. The lookat element contains a list of 9 floating-point values. As in the OpenGL® Utilities (GLU) implementation, these values are organized into three vectors as follows: * Eye position is given as Px, Py, Pz. * Interest point is given as Ix, Iy, Iz. * Up-axis direction is given as UPx, UPy, UPz. When computing the equivalent (viewing) matrix the interest point is mapped to the negative Z-axis and the eye position to the origin. The up-axis is mapped to the positive Y-axis of the viewing plane. The values are specified in local, object coordinates.

Member Function Documentation

daeElementRef domLookat::create (  daeInt  bytes  )  [static]
 

Creates an instance of this class and returns a daeElementRef referencing it.

Parameters:
bytes The size allocated for this instance.
Returns:
a daeElementRef referencing an instance of this object.

xsNCName domLookat::getSid (   )  const [inline]
 

Gets the sid attribute.

Returns:
Returns a xsNCName of the sid attribute.

const domFloat3x3& domLookat::getValue (   )  const [inline]
 

Gets the _value array.

Returns:
Returns a constant domFloat3x3 reference of the _value array.

domFloat3x3& domLookat::getValue (   )  [inline]
 

Gets the _value array.

Returns:
Returns a domFloat3x3 reference of the _value array.

daeMetaElement * domLookat::registerElement (   )  [static]
 

Creates a daeMetaElement object that describes this element in the meta object reflection framework.

If a daeMetaElement already exists it will return that instead of creating a new one.

Returns:
A daeMetaElement describing this COLLADA element.

void domLookat::setSid (  xsNCName  atSid  )  [inline]
 

Sets the sid attribute.

Parameters:
atSid The new value for the sid attribute.

void domLookat::setValue (  const domFloat3x3 &  val  )  [inline]
 

Sets the _value array.

Parameters:
atSid The new value for the _value array.

Member Data Documentation

xsNCName domLookat::attrSid [protected]
 

The sid attribute is a text string value containing the sub-identifier of this element.

This value must be unique within the scope of the parent element. Optional attribute.
