| 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. | |

Member Function Documentation
◆ GetFlags()
template<int N>
|
inlineoverridevirtual |
Returns a set of bit flags specifying which functions are implemented for this region (see RegFlags).
- Returns
- HAS_TESTPOINT|HAS_CLONE
Reimplemented from Region< N >.
◆ TestLine()
template<int N>
|
overridevirtual |
Records the fractions frac1 and frac2 of the line (p,dir) corresponding to the intersections surfpi=p+fraci*dir, surfni - coords of intersection and corresponding outer normal.
Intersections with frac<=epsilon are ignored. Returns the number of intersections: 0, 1 (touching or intersection of infinite region) or 2 because region is convex.
Reimplemented from Region< N >.
The documentation for this class was generated from the following files:
