Detailed Description
template<typename _Scalar, int _Dim>
class Eigen::Translation< _Scalar, _Dim >
Represents a translation transformation
- Parameters:
-
_Scalar the scalar type, i.e., the type of the coefficients. _Dim the dimension of the space, can be a compile time value or Dynamic
- Note:
- This class is not aimed to be used to store a translation transformation, but rather to make easier the constructions and updates of Transform objects.

Member Function Documentation
internal::cast_return_type<Translation,Translation<NewScalarType,Dim> >::type cast | ( | ) | const |
- Returns:
*this
with scalar type casted to NewScalarType
Note that if NewScalarType is equal to the current scalar type of *this
then this function smartly returns a const reference to *this
.
