Collaboration diagram for Circle:
Public Member Functions | |
| Circle (const vec_type &R, const Vector_2 ¢er) | |
| R is radius, center is center of the circle. | |
| virtual RegDumper< 2 > * | CreateDumper () const override |
| return pointer on object RegDumper, which has function Dump drawing the region | |
 Public Member Functions inherited from Sphere_N< 2 > | |
| virtual int | GetFlags () const override |
| Returns a set of bit flags specifying which functions are implemented for this region (see RegFlags). | |
| void | init (const vec_type &R_, const vector_t ¢er_) |
| R is radius of the sphere, center is the center of the sphere. | |
| Public Member Functions inherited from Region< N > | |
| virtual vec_type | SurfProject (const vector_t &p, vector_t *surfp=nullptr, vector_t *surfn=nullptr) const |
| finds the point on the region surface closest to the given one p returns distance to this point (positive is P outside and negative is P inside region), surfp – projection, surfn – norm vector at surfp | |
| template<class contour_t > | |
| vec_type | TestContour (const contour_t &cnt, VecContour< N > *subcont=nullptr, vector_t *subcenter=nullptr) const |
| Returns the area fraction of the contour part that is inside the region, subcontour which is inside the region (if pointer is not nullptr) and the center of the subcontour (if pointer is not nullptr) | |
| virtual vec_type | TestPtrContour (const PtrContour< N > &cnt, VecContour< N > *subcont=nullptr, vector_t *subcenter=nullptr) const |
| virtual version of TestContour for particular PtrContour | |
| virtual vector_t | GetCenter () const |
| Returns the center of the region. | |
| virtual vec_type | Volume () const |
| Returns volume of the region. '-1' means that function is not implemented. | |
| virtual vec_type | GetInsideEdgePart (const vector_t &p1, const vector_t &p2) const |
| Returns a fraction of the edge [0-1] that belongs to the region. | |
| virtual vec_type | TestEdge (const vector_t &p1, const vector_t &p2, vector_t *surfp=nullptr, vector_t *surfn=nullptr) const |
| Returns a fraction of the edge from the first point till the intersection with the surface of the region. | |
| virtual vec_type | TestRay (const vector_t &p1, const vector_t &dir, vector_t *surfp=nullptr, vector_t *surfn=nullptr, vec_type epsilon=0) const |
| Returns the fraction of the ray corresponding to the nearest intersection in positive direction frac<0 means no intersection in positive direction intersections with frac<=epsilon are ignored. | |
| virtual size_t | GetElementarySubRegions (std::vector< int > *flags=nullptr, std::vector< Region * > *regs=nullptr) const |
| For composite regions returns the number of elementary subregions, otherwise returns 0. | |
Additional Inherited Members | |
| Public Types inherited from Region< N > | |
| typedef unknown_cat | category |
| Category of the region to determine the correct template behaviour for various algorithms (see Body categories categories). | |
