Member Function Documentation

◆ Display()

virtual void V3d_PositionLight::Display	(	const Handle< V3d_View > &	theView,
		const V3d_TypeOfRepresentation	theRepresentation = `V3d_SIMPLE`
	)

virtual

Display the graphic structure of light source in the chosen view. We have three type of representation.

SIMPLE : Only the light source is displayed.
PARTIAL : The light source and the light space are displayed.
COMPLETE : The light source, the light space and the radius of light space are displayed. We can choose the "SAMELAST" as parameter of representation In this case the graphic structure representation will be the last displayed.

Reimplemented in V3d_SpotLight, V3d_PositionalLight, and V3d_DirectionalLight.

◆ Erase()

void V3d_PositionLight::Erase ( )

Erase the graphic structure of light source.

◆ OnHideFace()

void V3d_PositionLight::OnHideFace ( const Handle< V3d_View > & theView )

Calculate the position of the light, on the hide face of the picking sphere.

◆ OnSeeFace()

void V3d_PositionLight::OnSeeFace ( const Handle< V3d_View > & theView )

Calculate the position of the light, on the seen face of the picking sphere.

◆ Position()

virtual void V3d_PositionLight::Position	(	Standard_Real &	theX,
		Standard_Real &	theY,
		Standard_Real &	theZ
	)		const

pure virtual

Returns the position of the light source.

Implemented in V3d_SpotLight, V3d_PositionalLight, and V3d_DirectionalLight.

◆ Radius()

Standard_Real V3d_PositionLight::Radius ( ) const

Returns the radius of the picking sphere.

◆ SeeOrHide()

Standard_Boolean V3d_PositionLight::SeeOrHide ( const Handle< V3d_View > & theView ) const

Returns the visibility status If True the source is visible. If False it's hidden.

◆ SetPosition()

virtual void V3d_PositionLight::SetPosition	(	const Standard_Real	theX,
		const Standard_Real	theY,
		const Standard_Real	theZ
	)

pure virtual

Defines the position of the light source. Should be redefined!

Implemented in V3d_SpotLight, V3d_PositionalLight, and V3d_DirectionalLight.

◆ SetRadius()

void V3d_PositionLight::SetRadius ( const Standard_Real theRadius )

Define the radius.

◆ SetTarget()

void V3d_PositionLight::SetTarget	(	const Standard_Real	theX,
		const Standard_Real	theY,
		const Standard_Real	theZ
	)

Defines the target of the light (the center of the sphere).

◆ Target()

void V3d_PositionLight::Target	(	Standard_Real &	theX,
		Standard_Real &	theY,
		Standard_Real &	theZ
	)		const

Returns the position of the target of the light source.

◆ Tracking()

void V3d_PositionLight::Tracking	(	const Handle< V3d_View > &	theView,
		const V3d_TypeOfPickLight	theWathPick,
		const Standard_Integer	theXpix,
		const Standard_Integer	theYpix
	)

Tracking the light position, or the light space, or the radius of the light space, that depends of initial picking "theWhatPick" (see the pick method). If theWhatPick is SPACELIGHT, then the parameters theXpix, theYpix are the coordinates of a translation vector.
