Member Function Documentation

◆ Reset()

ILINE void AABB::Reset

(

)

inline

Reset Bounding box before calculating bounds. These values ensure that Add() functions work correctly for Reset bbs, without additional comparisons.

◆ SetAABBfromOBB()

template

ILINE void AABB::SetAABBfromOBB	(	const Vec3 &	wpos,
		const OBB_tpl< F > &	obb,
		f32	scaling = `1.0f`
	)

inline

converts an OBB into an tight fitting AABB

Example: AABB aabb = AABB::CreateAABBfromOBB(wposition,obb,1.0f);

return values: expanded AABB in world-space

◆ SetTransformedAABB()

ILINE void AABB::SetTransformedAABB	(	const Matrix34 &	m34,
		const AABB &	aabb
	)

inline

calculate the new bounds of a transformed AABB

Example: AABB aabb = AABB::CreateAABBfromOBB(m34,aabb);

return values: expanded AABB in world-space
