Detailed Description

An scene node that is associated with a shape.

Abstract class for graphical objects, that is, objects that have shapes to be drawn. A graphical object may, or may not, be visible without affecting scene graph traversal.

Member Function Documentation

virtual void VART::GraphicObj::ComputeBoundingBox ( )

pure virtual

Computes the bounding box.

Implemented in VART::MeshObject, VART::PolyLine, VART::Sphere, VART::Cone, VART::Cylinder, VART::Dot, and VART::RefSystem.

void VART::GraphicObj::ComputeRecursiveBoundingBox ( )

Computes the recursive bounding box.

This method requires a correct bounding box, therefore it should usually be called after ComputeBoundingBox.

Definition at line 63 of file graphicobj.cpp.

References ComputeRecursiveBoundingBox(), GetRecursiveBoundingBox(), and VART::Transform::RecursiveBoundingBox().

Referenced by VART::Scene::ComputeBoundingBox(), ComputeRecursiveBoundingBox(), and VART::Transform::RecursiveBoundingBox().

void VART::GraphicObj::DrawForPicking ( ) const

virtual

Draws and object, setting pick info.

This method should be called in selection mode in order to identify objects that are selected by the mouse (see Scene::Pick).

Implements VART::SceneNode.

Definition at line 90 of file graphicobj.cpp.

const BoundingBox& VART::GraphicObj::GetBoundingBox ( ) const

inline

Returns the bounding box.

Definition at line 49 of file graphicobj.h.

References bBox.

const BoundingBox& VART::GraphicObj::GetRecursiveBoundingBox ( ) const

inline

Returns the recursive bounding box.

Definition at line 58 of file graphicobj.h.

References recBBox.

Referenced by VART::Scene::ComputeBoundingBox(), ComputeRecursiveBoundingBox(), and VART::Transform::RecursiveBoundingBox().

void VART::GraphicObj::Hide ( )

Makes the object invisible.

Definition at line 23 of file graphicobj.cpp.

bool VART::GraphicObj::IsVisible ( )

Checks whether the object is visible.

Definition at line 59 of file graphicobj.cpp.

unsigned int VART::GraphicObj::PickName ( ) const

inline

Returns the pick name.

The pick name is used when picking objects with the mouse. Selection methods return the pick name which can be searched for in the scene graph.

Definition at line 70 of file graphicobj.h.

References pickName.

void VART::GraphicObj::Show ( )

Makes the object visible.

Definition at line 19 of file graphicobj.cpp.

void VART::GraphicObj::ToggleBBoxVisibility ( )

Toggles the bounding box visibility.

Definition at line 51 of file graphicobj.cpp.

void VART::GraphicObj::ToggleRecBBoxVisibility ( )

Toggles the recursive bounding box visibility.

Definition at line 55 of file graphicobj.cpp.

void VART::GraphicObj::ToggleRecVisibility ( )

Toggles the recursive object's visibility.

Definition at line 31 of file graphicobj.cpp.
