virtual void makVrv::DtAttachableIntervisibilityUpdater::setFixedDistance

(

bool

)

[virtual]

If true, sets the end point to be a fixed distance (given the current distance) from the start point, if the start points moves and the end point is not attached.

Default is false

virtual void makVrv::DtAttachableIntervisibilityUpdater::update

(

double

)

[protected, virtual]

Sees if intervisibility needs to be recalculated, and, if so recalculates and sets all associated lines.

Reimplemented from makVrv::DtLineModelUpdater.

Reimplemented in makVrv::DtAttachableEntityFanUpdater.

virtual bool makVrv::DtAttachableIntervisibilityUpdater::doIntersection

(

)

[protected, virtual]

Does intersection if points have changed. Returns true if something has changed.

Reimplemented in makVrv::DtAttachableEntityFanUpdater, and makVrv::DtAttachableFanUpdater.
