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
lightInfoGathered light info.

Member Function Documentation

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
referenceNodeNode with which to update the distance.
bool kanzi::GatherNearestLightsRenderPass::LightDistanceInfo::operator< ( const LightDistanceInfo other) const
inline

Less than operator for sorting.

Parameters
otherOther 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.
