Member Function Documentation

clone()

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

overridevirtual

Implements inviwo::Event.

getCanvasSize()

uvec2 inviwo::PickingEvent::getCanvasSize

(

)

const

The size of the canvas where the event occurred.

getCurrentGlobalPickingId()

size_t inviwo::PickingEvent::getCurrentGlobalPickingId

(

)

const

Returns the current global picking index of the object at the current position

getCurrentLocalPickingId()

std::pair< bool, size_t > inviwo::PickingEvent::getCurrentLocalPickingId

(

)

const

Returns the current local picking index If the global index belongs to a different picking action {false, 0} is returned.

getDeltaDepth()

double inviwo::PickingEvent::getDeltaDepth

(

)

const

Returns the delta of the previous and current depth;

getDeltaPosition()

dvec2 inviwo::PickingEvent::getDeltaPosition

(

)

const

Returns the delta of the previous and current position;

getDeltaPressedDepth()

double inviwo::PickingEvent::getDeltaPressedDepth

(

)

const

Returns the delta of the press depth and current depth;

getDeltaPressedPosition()

dvec2 inviwo::PickingEvent::getDeltaPressedPosition

(

)

const

Returns the delta of the press position and current position;

getDepth()

double inviwo::PickingEvent::getDepth

(

)

const

Returns the current normalized depth

getGlobalPickingId()

size_t inviwo::PickingEvent::getGlobalPickingId

(

)

const

Returns the global picking index of the object currently being picked. this id does not change while an item is being pressed even if the position is no longer on the item.

getMovedSincePressed()

bool inviwo::PickingEvent::getMovedSincePressed

(

double

deltaDistance = 3.0

)

const

Returns true if the distance between the pressed position and current position in screen coordinates is larger than deltaDistance or the current picking ID is different to the pressed one.

getCurrentGlobalPickingId, getPressedGlobalPickingId, getDeltaPressedPosition

getNDC()

dvec3 inviwo::PickingEvent::getNDC

(

)

const

Returns the normalized device coordinates. Position and depth normalized to the range of (-1,1) In in a left handed coordinate system. The lower left near will be (-1,-1,-1) And the upper right far (1,1,1)

getPickedId()

size_t inviwo::PickingEvent::getPickedId

(

)

const

Returns the local picking index of the object currently being picked. this id does not change while an item is being pressed even if the position is no longer on the item.

getPosition()

dvec2 inviwo::PickingEvent::getPosition

(

)

const

Returns the current normalized position

getPressedDepth()

double inviwo::PickingEvent::getPressedDepth

(

)

const

Returns the normalized depth of the initial press

getPressedGlobalPickingId()

size_t inviwo::PickingEvent::getPressedGlobalPickingId

(

)

const

Returns the pressed global picking index

getPressedLocalPickingId()

std::pair< bool, size_t > inviwo::PickingEvent::getPressedLocalPickingId

(

)

const

Returns the pressed local picking index If the global index belongs to a different picking action {false, 0} is returned.

getPressedPosition()

dvec2 inviwo::PickingEvent::getPressedPosition

(

)

const

Returns the normalized position of the initial press

getPreviousDepth()

double inviwo::PickingEvent::getPreviousDepth

(

)

const

Returns the previous global picking index

getPreviousLocalPickingId()

std::pair< bool, size_t > inviwo::PickingEvent::getPreviousLocalPickingId

(

)

const

Returns the previous local picking index If the global index belongs to a different picking action {false, 0} is returned.

getPreviousPosition()

dvec2 inviwo::PickingEvent::getPreviousPosition

(

)

const

Returns the previous normalized position

getWorldSpaceDeltaAtPressDepth()

dvec3 inviwo::PickingEvent::getWorldSpaceDeltaAtPressDepth

(

const Camera &

camera

)

const

Return the {curr.x, curr.y. press.z} - {prev.x, prev.y, press.z} transformed into world space using the given camera. This is useful when dragging an object in the screen plane.

hash()

virtual uint64_t inviwo::PickingEvent::hash ( ) const

overridevirtual

Implements inviwo::Event.

print()

virtual void inviwo::PickingEvent::print ( std::ostream & ss ) const

overridevirtual

Reimplemented from inviwo::Event.

setToolTip()

void inviwo::PickingEvent::setToolTip

(

std::string_view

tooltip

)

const

Display a tool tip using the optionally set tool tip callback. If no tool tip callback is set, the function does nothing. The supported formation depends on the used back end, but simple html is usually supported. Calling the function with an empty sting will hide any existing tool tip.
