Detailed Description

Constructor & Destructor Documentation

◆ Physical() [1/2]

Physical::Physical	(	int	total_objects = `1`,
		bool	pre_alloc = `false`
	)

explicit

Default Constructor The idea here is that most physicals will NOT be collections of sets (i.e.

particle systems and whatever else). Because of this, the default constructor, unless otherwise specified, will automatically allocate and initialize one PhysicalObject. This makes it easier for high-level work.

pre-alloc is ONLY for multiple-object physicals, and if true, fills the physics_object vector with dead nodes, pre-allocating for the speed end of the speed-vs-overhead deal.
