Member Function Documentation
◆ Clone()
- Returns
- a copy of itself optionally shifted in space with the shift vector
Reimplemented from Box_N< 3 >.
◆ GetFlags()
|
inlineoverridevirtual |
Returns a set of bit flags specifying which functions are implemented for this region (see RegFlags).
- Returns
- HAS_TESTPOINT|HAS_TESTLINE|HAS_TESTCONTOUR|HAS_CLONE|HAS_VOLUME
Reimplemented from Box_N< 3 >.
◆ TestLine()
|
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 >.
