	This member function must draw the object. It will be called at every frame.
Box3d	boundingBox () const override
	This member function is used to find a good camera position to render object. It should return the the bounding box of the object. Return a null bounding box if the object shouldn't influence the position of the camera.
std::shared_ptr< DrawableObject >	clone () const &override
	This member function is used to create a new copy of the DrawableObject. Each derived class must implement this member function, that returns a shared pointer pointing to a copy of the current one. for more details about this paradigm, check polimorphism clone in modern c++: https://www.fluentcpp.com/2017/09/08/make-polymorphic-copy-modern-cpp/.

Member Function Documentation

boundingBox()

Box3d vcl::DrawableTrackBall::boundingBox ( ) const

inlineoverridevirtual

This member function is used to find a good camera position to render object. It should return the the bounding box of the object. Return a null bounding box if the object shouldn't influence the position of the camera.

Returns

The bounding box of the object.

Implements vcl::DrawableObject.

clone() [1/2]

std::shared_ptr< DrawableObject > vcl::DrawableTrackBall::clone ( ) &&

inlineoverridevirtual

This member function is used to create a new DrawableObject that is a moved from the current one. This object will be destroyed after the call of this function. Each derived class must implement this member function, that returns a shared pointer pointing to the moved object. For more details about this paradigm, check polimorphism clone in modern c++: https://www.fluentcpp.com/2017/09/08/make-polymorphic-copy-modern-cpp/.

Generally, if your class that inherits from DrawableObject is called MyObject, the clone member function should be implemented as follows:

std::shared_ptr<DrawableObject> MyObject::clone() &&
{
   return std::make_shared<MyObject>(std::move(*this));
}

Returns

A shared pointers that points to a new DrawableObject that is a moved from the current one.

Implements vcl::DrawableObject.

clone() [2/2]

std::shared_ptr< DrawableObject > vcl::DrawableTrackBall::clone ( ) const &

inlineoverridevirtual

This member function is used to create a new copy of the DrawableObject. Each derived class must implement this member function, that returns a shared pointer pointing to a copy of the current one. for more details about this paradigm, check polimorphism clone in modern c++: https://www.fluentcpp.com/2017/09/08/make-polymorphic-copy-modern-cpp/.

Generally, if your class that inherits from DrawableObject is called MyObject, the clone member function should be implemented as follows:

std::shared_ptr<DrawableObject> MyObject::clone() const&
{
   return std::make_shared<MyObject>(*this);
}

Returns

A shared pointers that points to a new DrawableObject that is a copy of the current one.

Implements vcl::DrawableObject.

draw()

void vcl::DrawableTrackBall::draw ( uint  viewId ) const

inlineoverridevirtual

This member function must draw the object. It will be called at every frame.

Parameters

viewId

The ID of the view to draw. It may be used depending on the rendering engine.

Implements vcl::DrawableObject.

isVisible()

bool vcl::DrawableTrackBall::isVisible ( ) const

inlineoverridevirtual

This member function is used to check if the object is visible.

Returns

true if the object is visible;

Implements vcl::DrawableObject.

setVisibility()

void vcl::DrawableTrackBall::setVisibility ( bool  vis )

inlineoverridevirtual

This member function is used to set the visibility of the object.

Parameters

[in]

vis

true if the object should be visible;

Implements vcl::DrawableObject.

swap()

void vcl::DrawableTrackBall::swap ( DrawableTrackBall &  other )

inline

Swap the content of this object with another DrawableTrackBall object.

Parameters

[in]

other

the other DrawableTrackBall object.

updateDragging()

void vcl::DrawableTrackBall::updateDragging ( bool  isDragging )

inline

Update the dragging status of the trackball.

Parameters

[in]

isDragging

true if the trackball is being dragged, false otherwise.
