- make read construct from Istream explicit
BUG: sph(const SymmTensor2D<Cmpt>&)
- had incorrect constant, but the 2D routines still need more attention
(#1575)
- change contiguous from a series of global functions to separate
templated traits classes:
- is_contiguous
- is_contiguous_label
- is_contiguous_scalar
The static constexpr 'value' and a constexpr conversion operator
allow use in template expressions. The change also makes it much
easier to define general traits and to inherit from them.
The is_contiguous_label and is_contiguous_scalar are special traits
for handling data of homogeneous components of the respective types.
- adjust naming of quaternion 'rotationSequence' to be 'eulerOrder'
to reflect its purpose.
- provide rotation matrices directly for these rotation orders in
coordinateRotations::euler for case in which the rotation tensor
is required but not a quaternion.
The particular rotation sequence is specified via the enumeration:
//- Euler-angle rotation sequence
enum rotationSequence
{
ZYX, ZYZ, ZXY, ZXZ, YXZ, YXY, YZX, YZY, XYZ, XYX, XZY, XZX
};
and provided as an argument to the constructor from Euler-angles
//- Construct a quaternion given the three Euler angles:
inline quaternion
(
const rotationSequence rs,
const vector& angles
);
and conversion to Euler-angles:
//- Return a vector of euler angles corresponding to the
// specified rotation sequence
inline vector eulerAngles(const rotationSequence rs) const;
Foam::direction is an unsigned type which makes it easier for the
compiler to pickup and report errors in the instantiation of
VectorSpaces and associated types.
