Public Member Functions

virtual SoType getTypeId (void) const

Static Public Member Functions inherited from ScXMLObject
static SoType getClassTypeId (void)
This static method returns the SoType object associated with objects of this class.
static void initClass (void)
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
static void cleanClass (void)
Does the opposite of initClass, deallocates any class specific resources and resets the class to an uninitialized state with respect to the Coin type system.

Constructor & Destructor Documentation

SoScXMLDollyTarget::SoScXMLDollyTarget (void ) [protected]

The constructor registers the singleton with the proper name and target type.

Member Function Documentation

SoType SoScXMLDollyTarget::getTypeId (void ) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

See also: SoBase::getTypeId() const

Implements SoScXMLNavigationTarget.

const SbName & SoScXMLDollyTarget::BEGIN (void ) [static]

Returns the full name for the dolly BEGIN SCXML event.

const SbName & SoScXMLDollyTarget::UPDATE (void ) [static]

Returns the full name for the dolly UPDATE SCXML event.

const SbName & SoScXMLDollyTarget::END (void ) [static]

Returns the full name for the dolly END SCXML event.

const SbName & SoScXMLDollyTarget::JUMP (void ) [static]

Returns the full name for the dolly JUMP SCXML event.

const SbName & SoScXMLDollyTarget::STEP_IN (void ) [static]

Returns the full name for the dolly STEP_IN SCXML event.

const SbName & SoScXMLDollyTarget::STEP_OUT (void ) [static]

Returns the full name for the dolly STEP_OUT SCXML event.

void SoScXMLDollyTarget::jump (SoCamera * camera, float focaldistance) [static]

Jumps the camera to focaldistance distance from the current focal point of the camera. This function only changes the SoCamera::position field.

This function is more or less useless to use on an SoOrthographicCamera.

void SoScXMLDollyTarget::step (SoCamera * camera, SbBool exponential, float diff, float mindistance = 0.0f, float maxdistance = 0.0f) [static]

Steps the camera relative to its orientation and focal point by diff.

If exponential is FALSE, then the diff value is treated as an absolute distance value.

If mindistance and/or maxdistance is anything but 0.0, they are checked against the focal distance, and the focal distance will be clamped inside the range. Both are not needed, if only one is specified, only that part of the range will be used to limit the dollying.

If exponential is TRUE...FIXME
