Member Function Documentation

void makVrv::DtLightScreenSpaceData::calculate	(	const DtLight &	,
		const DtLightScreenSpacePerViewData &	perView,
		int	viewMatrix
	)

Calculate screen space light parameters.

This is called from a subthread in DtTileSpaceLightGrid to calculate per-light screenspace parameters that can be re-used whilst adding lights to many light bins.

bool makVrv::DtLightScreenSpaceData::intersect

(

const DtScreenRect &

rect

)

const

true if we intersect the given screen area

uint32 makVrv::DtLightScreenSpaceData::area ( ) const

inline

Return screenspace area.

const DtScreenRect& makVrv::DtLightScreenSpaceData::screenRect ( ) const

inline

Return screenspace bounding rectangle.

bool makVrv::DtLightScreenSpaceData::insideEllipse ( float  xDiff, float  yDiff  ) const

protected

True if given point lies inside screen space projected point light ellipse.

bool makVrv::DtLightScreenSpaceData::insideSpot ( const Vector2_32 &  relPos ) const

protected

True if given point lies inside screen space projected spot light cone.
