Constructor & Destructor Documentation

◆ Trackball()

inviwo::Trackball::Trackball ( TrackballObject * object )

Rotates and moves object around a sphere. The trackball does not take ownership of pointers handed to it.

See also: CameraTrackball

Member Function Documentation

◆ clone()

virtual Trackball * inviwo::Trackball::clone ( ) const

overridevirtual

Creates a clone of this property. The clone will have the same identifier, hence the identifier must be changed if the clone should be added to the same owner as this. The new clone does not have any owner set.

Reimplemented from inviwo::CompositeProperty.

Reimplemented in inviwo::CameraTrackball.

◆ getClassIdentifier()

virtual std::string_view inviwo::Trackball::getClassIdentifier ( ) const

overridevirtual

Reimplemented from inviwo::CompositeProperty.

◆ invokeEvent()

virtual void inviwo::Trackball::invokeEvent ( Event * event )

overridevirtual

Reimplemented from inviwo::PropertyOwner.

◆ setLook()

void inviwo::Trackball::setLook	(	vec3	lookFrom,
		vec3	lookTo,
		vec3	lookUp )

Set look from, look to and up vector at the same time. Should be used when more than one parameter will be changed to avoid duplicate evaluations.

Parameters

lookFrom
lookTo
lookUp

◆ touchGesture()

void inviwo::Trackball::touchGesture ( Event * event )

protected

Rotates around the direction vector, zooms along the direction vector and translates along up/right vector.

Parameters

event TouchEvent

Member Data Documentation

◆ handleInteractionEvents_

BoolProperty inviwo::Trackball::handleInteractionEvents_

Limits the angle between world up and view direction when fixUp is True

◆ sensitivity_

FloatProperty inviwo::Trackball::sensitivity_

Chooses which trackball method to use (mouse only, touch always follows finger)

The documentation for this class was generated from the following file:

trackball.h
