Detailed Description

SphereSensor node instances.

Constructor & Destructor Documentation

SphereSensor (  const NodeType &    nodeType, const ScopePtr &    scope )

Constructor. Parameters: nodeType  the NodeType associated with the node instance. scope  the Scope to which the node belongs.

~SphereSensor (    )  throw () [virtual]

Destructor.

Member Function Documentation

void activate (  double    timeStamp, bool    isActive, double *    p )

Activate or deactivate the SphereSensor. Activating a drag sensor means that the pointing device button has been depressed and a drag operation has been initiated. The sensor is deactivated when the button is released at the end of the operation. Parameters: timeStamp  the current time. isActive  true if the drag operation is in progress; false otherwise. p  the pointing device position.

bool isEnabled (    )  const throw ()

Determine whether the SphereSensor is enabled. Returns: true if the SphereSensor is enabled; false otherwise.

void processSet_autoOffset (  const FieldValue &    sfbool, double    timestamp )  throw (std::bad_cast) [private]

set_autoOffset eventIn handler. Parameters: sfbool  an SFBool value. timestamp  the current time. Exceptions: std::bad_cast  if sfbool is not an SFBool.

void processSet_enabled (  const FieldValue &    sfbool, double    timestamp )  throw (std::bad_cast) [private]

set_enabled eventIn handler. Parameters: sfbool  an SFBool value. timestamp  the current time. Exceptions: std::bad_cast  if sfbool is not an SFBool.

void processSet_offset (  const FieldValue &    sfrotation, double    timestamp )  throw (std::bad_cast) [private]

set_offset eventIn handler. Parameters: sfrotation  an SFRotation value. timestamp  the current time. Exceptions: std::bad_cast  if sfrotation is not an SFRotation.

void render (  Viewer &    viewer, VrmlRenderContext    context )  [virtual]

Render the node. Parameters: viewer  a Viewer. context  a rendering context. Reimplemented from Node.

SphereSensor * toSphereSensor (    )  const [virtual]

Cast to a SphereSensor. Returns: a pointer to the node. Reimplemented from Node.
