Member Function Documentation
◆ GetNormalized()
template<class Real >
|
inline |
Return a normalized copy of this vector, with euclidean length = 1.
Not to be confused with Normalize() which normalizes in place.
◆ Normalize()
template<class Real >
|
inline |
Normalize this vector in place, so that its euclidean length is 1.
Return false if the original vector had zero length (in which case the vector set to [1,0,0]) and return true otherwise.
◆ operator*()
template<class Real>
|
inline |
Operator for element-wise multiplication.
Note that this is not the dot product.
◆ SetNull()
template<class Real >
|
inline |
Set the vector to the null vector.
Sets the vector as a null vector.
