CGAL 5.3 - 3D Periodic Triangulations
|
The concept Periodic_3Offset_3
describes a three-dimensional integer vector with some specialized access functions and operations.
Creation | |
Periodic_3Offset_3 () | |
Default constructor. | |
Periodic_3Offset_3 (int x, int y, int z) | |
Constructs the offset (x,y,z). | |
Operations | |
Periodic_3Offset_3 | operator+ (const Periodic_3Offset_3 &other) const |
Return the vector sum of o and other . | |
Periodic_3Offset_3 | operator- (const Periodic_3Offset_3 &other) const |
Return the vector difference of o and other . | |
Periodic_3Offset_3 | operator- () const |
Return the negative vector of o . | |
void | operator+= (const Periodic_3Offset_3 &other) const |
Add other to o using vector addition. | |
void | operator-= (const Periodic_3Offset_3 &other) const |
Subtract other from o using vector subtraction. | |
bool | operator== (const Periodic_3Offset_3 &other) const |
Return true if other and o represent the same vector. | |
bool | operator!= (const Periodic_3Offset_3 &other) const |
Return true if other and o do not represent the same vector. | |
bool | operator< (const Periodic_3Offset_3 &other) const |
Compare o and other lexicographically. | |
Access Functions | |
int | operator[] (int i) |
Return the \( i\)-th entry of o . | |
int | x () const |
Return the \( x\)-entry of o . | |
int | y () const |
Return the \( y\)-entry of o . | |
int | z () |
Return the \( z\)-entry of o . | |
bool | is_null () const |
Returns true if o is equal to (0,0,0). | |
istream & | operator>> (istream &is, Periodic_3_offset_3 &off) |
Inputs an offset from is . | |
ostream & | operator<< (ostream &os, Periodic_3_offset_3 &off) const |
Outputs an offset from os . | |
