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.
