Scene::preCalc()
{
Objects::iterator it;
for (it = m_objects.begin(); it != m_objects.end(); it++)
{
Object* pObject = *it;
pObject->preCalc();
}
Lights::iterator lit;
float total_wattage = 0.f;
for (lit = m_lights.begin(); lit != m_lights.end(); lit++)
{
PointLight* pLight = *lit;
pLight->preCalc();
total_wattage += pLight->wattage();
}
