Detailed Description

Helper class for keeping reference on world-view-projection state. Helpful for synchronizing state of WVP dependent data structures.

Constructor & Destructor Documentation

Graphic3d_WorldViewProjState() [1/2]

Graphic3d_WorldViewProjState::Graphic3d_WorldViewProjState ( )

inline

Default constructor.

Graphic3d_WorldViewProjState() [2/2]

Graphic3d_WorldViewProjState::Graphic3d_WorldViewProjState ( const Standard_Size  theProjectionState, const Standard_Size  theWorldViewState, const Standard_Transient *  theCamera = NULL  )

inline

Constructor for custom projector type.

Parameters

theProjectionState	[in] the projection state.
theWorldViewState	[in] the world view state.
theCamera	[in] the pointer to the class supplying projection and world view matrices (camera).

Member Function Documentation

Initialize() [1/2]

void Graphic3d_WorldViewProjState::Initialize ( const Standard_Size  theProjectionState, const Standard_Size  theWorldViewState, const Standard_Transient *  theCamera = NULL  )

inline

Initialize world view projection state.

Initialize() [2/2]

void Graphic3d_WorldViewProjState::Initialize ( const Standard_Transient *  theCamera = NULL )

inline

Initialize world view projection state.

IsChanged()

Standard_Boolean Graphic3d_WorldViewProjState::IsChanged ( const Graphic3d_WorldViewProjState &  theState )

inline

Compare with other world view projection state.

Returns

true when the projection of the given camera state differs from this one.

IsProjectionChanged()

Standard_Boolean Graphic3d_WorldViewProjState::IsProjectionChanged ( const Graphic3d_WorldViewProjState &  theState )

inline

Compare projection with other state.

Returns

true when the projection of the given camera state differs from this one.

IsValid()

Standard_Boolean Graphic3d_WorldViewProjState::IsValid ( )

inline

Check state validity.

Returns

true if state is set.

IsWorldViewChanged()

Standard_Boolean Graphic3d_WorldViewProjState::IsWorldViewChanged ( const Graphic3d_WorldViewProjState &  theState )

inline

Compare world view transformation with other state.

Returns

true when the orientation of the given camera state differs from this one.

operator!=()

bool Graphic3d_WorldViewProjState::operator!= ( const Graphic3d_WorldViewProjState &  theOther ) const

inline

Compare with other world view projection state.

Returns

true if the other projection state is different to this one.

operator=()

void Graphic3d_WorldViewProjState::operator= ( const Graphic3d_WorldViewProjState &  theOther )

inline

Copy world view projection state.

operator==()

bool Graphic3d_WorldViewProjState::operator== ( const Graphic3d_WorldViewProjState &  theOther ) const

inline

Compare with other world view projection state.

Returns

true if the other projection state is equal to this one.

ProjectionState()

Standard_Size& Graphic3d_WorldViewProjState::ProjectionState ( )

inline

Returns

projection state counter.

Reset()

void Graphic3d_WorldViewProjState::Reset ( void  )

inline

Invalidate world view projection state.

WorldViewState()

Standard_Size& Graphic3d_WorldViewProjState::WorldViewState ( )

inline

Returns

world view state counter.
