This class implements a very simple implicit object: a sphere given its center and its radius.
|
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 >.

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