Member Function Documentation

void NL3D::CPointLightNamedArray::build (  const std::vector< CPointLightNamed > &  pointLights,
std::vector< uint > &  indexRemap
) 
 

sort pointLights and make Groups by name for setFactor(). indexRemap gets news Ids for pointLights. eg: old PointLight nb 0 is now at indexRemap[0].
