Inherits SoScXMLNavigationTarget.

Public Member Functions

virtual SoType getTypeId (void) const
Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

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 run-time 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 focaldistance, and the focaldistance 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

SbBool SoScXMLDollyTarget::processOneEvent (const ScXMLEvent * event) [protected], [virtual]

Dispatches incoming SCXML events to the corresponding functionality.

Reimplemented from ScXMLEventTarget.
