Detailed Description

Light distance information.

References a LightInfo structure from GatherLightsRenderPass. Adds distance so sorting is possible.

Constructor & Destructor Documentation

kanzi::GatherNearestLightsRenderPass::LightDistanceInfo::LightDistanceInfo ( LightInfo &  lightInfo )

explicit

Constructor.

Calculates distance internally.

Parameters

lightInfo

Gathered light info.

Member Function Documentation

LightInfo* kanzi::GatherNearestLightsRenderPass::LightDistanceInfo::getLightInfo ( )

inline

Gets the referred light.

Returns

Pointer to a light info struct.

void kanzi::GatherNearestLightsRenderPass::LightDistanceInfo::updateDistance

(

const Node3D &

referenceNode

)

Updates the distance based on a reference node.

Parameters

referenceNode

Node with which to update the distance.

bool kanzi::GatherNearestLightsRenderPass::LightDistanceInfo::operator< ( const LightDistanceInfo &  other ) const

inline

Less than operator for sorting.

Parameters

other

Other distance info compared against.

Returns

True if this is smaller than the counterpart.

Member Data Documentation

LightInfo* kanzi::GatherNearestLightsRenderPass::LightDistanceInfo::m_lightInfo

protected

Light information referred.

float kanzi::GatherNearestLightsRenderPass::LightDistanceInfo::m_distanceSquared

protected

Distance to light (from reference node).

Saved as squared, there is no need to take the root simply for comparison.
