LinearMatrixType | operator* (const LinearMatrixType &other, const Scaling &s) |
Represents a possibly non uniform scaling transformation.
This is defined in the Geometry module.
#include <Eigen/Geometry>
_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 |
typedef Matrix<Scalar,Dim,Dim> LinearMatrixType |
corresponding linear transformation matrix type
typedef _Scalar Scalar |
the scalar type of the coefficients
typedef Transform<Scalar,Dim> TransformType |
corresponding affine transformation type
typedef Translation<Scalar,Dim> TranslationType |
corresponding translation type
typedef Matrix<Scalar,Dim,1> VectorType |
corresponding vector type
anonymous enum |
dimension of the space
Scaling | ( | ) | [inline] |
Default constructor without initialization.
Constructs and initialize a uniform scaling transformation
Scaling | ( | const VectorType & | coeffs | ) | [inline, explicit] |
Constructs and initialize the scaling transformation from a vector of scaling coefficients
Copy constructor with scalar type conversion
*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
.
