Member Function Documentation

std::shared_ptr<Node> duplicateInstance ( ) const
overrideprotectedvirtual

Reimplemented from lysa::Node::duplicateInstance()

auto getCascadeSplitLambda ( ) const
inline
LightData getLightData ( ) const
overridevirtual

Reimplemented from lysa::Light::getLightData()

auto getShadowMapCascadesCount ( ) const
inline

Returns the number of cascades for the shadow map

void setCascadeSplitLambda ( const float  cascadeSplitLambda)
inline

Lambda constant for split depth calculation: the closer to 1.0 the smaller the firsts splits

void setProperty ( const std::string &  property,
const std::string &  value 
)
overridevirtual

Sets a property by its name and value. Currently, not all properties in all node classes are supported.

Reimplemented from lysa::Node::setProperty()

void setShadowMapCascadesCount ( uint32  cascadesCount)

Sets the number of cascades for the shadow map (between 2 and ShadowMapFrameBuffer::CASCADED_SHADOWMAP_MAX_LAYERS).
must be called before adding the light to the scene since this value is used when instancing the shadow map renderer for this light.
