Public Member Functions | |
Intersection (const Implicit &_implicit1, const Implicit &_implicit2) | |
Constructor: given the two implicit objects to intersect. | |
Mandatory interface of implicit objects, see also IsoEx::Implicit. | |
bool | is_inside (const OpenMesh::Vec3f &_p) const |
Is the point _point inside or outside w.r.t. | |
float | scalar_distance (const OpenMesh::Vec3f &_p) const |
Returns the scalar distance value of _point. | |
bool | directed_distance (const OpenMesh::Vec3f &_p0, const OpenMesh::Vec3f &_p1, OpenMesh::Vec3f &_point, OpenMesh::Vec3f &_normal, float &_distance) const |
This method returns the directed distance of _p0 in the direction _p1-_p0. |
|
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. |
|
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. |
|
Returns the scalar distance value of _point. Points inside the object should have negative distances, points outside positive distance. Implements IsoEx::Implicit. |
