Detailed Description

template<class Vec3>
class IsoEx::CSG::Intersection< Vec3 >

This class builds a CSG intersection of two other implicits.

template<class Vec3 >

bool IsoEx::CSG::Intersection< Vec3 >::directed_distance	(	const Vec3 &	_p0,
		const Vec3 &	_p1,
		Vec3 &	_point,
		Vec3 &	_normal,
		real &	_distance
	)		const

inlinevirtual

This method returns the directed distance of _p0 in the direction _p1-_p0. The resulting intersection point (casting a ray from _p0 in direction (_p1-_p0)) is stored in _point, the corresponding normal vector at this point is stored in _normal, the distance value is stored in _distance (again negative distance means _p0 is inside). Since the ray intersection may fail (because of precision problems) it is returned whether an intersection was found or not.

Implements IsoEx::Implicit< Vec3 >.

template<class Vec3 >

bool IsoEx::CSG::Intersection< Vec3 >::is_inside ( const Vec3 & _point ) const

inlinevirtual

Is the point _point inside or outside w.r.t. the implicit function? The result should be the same as scalar_distance(_point) < 0, but it can be implemented more efficiently.

Implements IsoEx::Implicit< Vec3 >.

template<class Vec3 >

real IsoEx::CSG::Intersection< Vec3 >::scalar_distance ( const Vec3 & _point ) const

inlinevirtual

Returns the scalar distance value of _point. Points inside the object should have negative distances, points outside positive distance.

Implements IsoEx::Implicit< Vec3 >.
