Public Member Functions
bool	overlap (const kIOS< S > &other) const
	Check collision between two kIOS.

bool	overlap (const kIOS< S > &other, kIOS< S > &overlap_part) const
	Check collision between two kIOS and return the overlap part. For kIOS, we return nothing, as the overlappart of two kIOS usually is not an kIOS. More...

bool	contain (const Vector3< S > &p) const
	Check whether the kIOS contains a point.

kIOS< S > &	operator+= (const Vector3< S > &p)
	A simple way to merge the kIOS and a point.

kIOS< S > &	operator+= (const kIOS< S > &other)
	Merge the kIOS and another kIOS.

kIOS< S >	operator+ (const kIOS< S > &other) const
	Return the merged kIOS of current kIOS and the other one.

const Vector3< S > &	center () const
	Center of the kIOS.

S	width () const
	Width of the kIOS.

	Height of the kIOS.

	Depth of the kIOS.

S	volume () const
	Volume of the kIOS.

Detailed Description

A class describing the kIOS collision structure, which is a set of spheres.

Member Function Documentation

template<typename S >

Check collision between two kIOS and return the overlap part. For kIOS, we return nothing, as the overlappart of two kIOS usually is not an kIOS.

Todo:: Not efficient. It first checks the sphere collisions and then use OBB for further culling.
