<UserDocu>Base.Placement class.\n
A Placement defines an orientation (rotation) and a position (base) in 3D space.
It is used when no scaling or other distortion is needed.\n
The following constructors are supported:\n
Placement()
Empty constructor.\n
Placement(placement)
Copy constructor.
placement : Base.Placement\n
Placement(matrix)
Define from a 4D matrix consisting of rotation and translation.
matrix : Base.Matrix\n
Placement(base, rotation)
Define from position and rotation.
base : Base.Vector
rotation : Base.Rotation\n
Placement(base, rotation, center)
Define from position and rotation with center.
base : Base.Vector
rotation : Base.Rotation
center : Base.Vector\n
Placement(base, axis, angle)
define position and rotation.
base : Base.Vector
axis : Base.Vector
angle : float</UserDocu>

<Methode Name="copy" Const="true">
<Documentation>
<UserDocu>copy() -> Base.Placement\n
Returns a copy of this placement.</UserDocu>
</Documentation>
</Methode>
<Methode Name="move">
<Documentation>
<UserDocu>move(vector) -> None\n
Move the placement along a vector.\n
vector : Base.Vector\n Vector by which to move the placement.</UserDocu>
</Documentation>
</Methode>
<Methode Name="translate">
<Documentation>
<UserDocu>translate(vector) -> None\n
Alias to move(), to be compatible with TopoShape.translate().\n
vector : Base.Vector\n Vector by which to move the placement.</UserDocu>
</Documentation>
</Methode>
<Methode Name="rotate" Keyword="true">
<Documentation>
<UserDocu>rotate(center, axis, angle, comp) -> None\n
Rotate the current placement around center and axis with the given angle.
This method is compatible with TopoShape.rotate() if the (optional) keyword
argument comp is True (default=False).
center : Base.Vector, sequence of float\n Rotation center.
axis : Base.Vector, sequence of float\n Rotation axis.
angle : float\n Rotation angle in degrees.
comp : bool\n optional keyword only argument, if True (default=False),
behave like TopoShape.rotate() (i.e. the resulting placements are interchangeable).
</UserDocu>
</Documentation>
</Methode>
<Methode Name="multiply" Const="true">
<Documentation>
<UserDocu>multiply(placement) -> Base.Placement\n
Right multiply this placement with another placement.
Also available as `*` operator.\n
placement : Base.Placement\n Placement by which to multiply this placement.</UserDocu>
</Documentation>
</Methode>
<Methode Name="multVec" Const="true">
<Documentation>
<UserDocu>multVec(vector) -> Base.Vector\n
Compute the transformed vector using the placement.\n
vector : Base.Vector\n Vector to be transformed.</UserDocu>
</Documentation>
</Methode>
<Methode Name="toMatrix" Const="true">
<Documentation>
<UserDocu>toMatrix() -> Base.Matrix\n
Compute the matrix representation of the placement.</UserDocu>
</Documentation>
</Methode>
<Methode Name="inverse" Const="true">
<Documentation>
<UserDocu>inverse() -> Base.Placement\n
Compute the inverse placement.</UserDocu>
</Documentation>
</Methode>
<Methode Name="pow" Const="true">
<Documentation>
<UserDocu>pow(t, shorten=True) -> Base.Placement\n
Raise this placement to real power using ScLERP interpolation.
Also available as `**` operator.\n
t : float\n Real power.
shorten : bool\n If True, ensures rotation quaternion is net positive to make
the path shorter.</UserDocu>
</Documentation>
</Methode>
<Methode Name="sclerp" Const="true">
<Documentation>
<UserDocu>sclerp(placement2, t, shorten=True) -> Base.Placement\n
Screw Linear Interpolation (ScLERP) between this placement and `placement2`.
Interpolation is a continuous motion along a helical path parametrized by `t`
made of equal transforms if discretized.
If quaternions of rotations of the two placements differ in sign, the interpolation
will take a long path.\n
placement2 : Base.Placement
t : float\n Parameter of helical path. t=0 returns this placement, t=1 returns
`placement2`. t can also be outside of [0, 1] range for extrapolation.
shorten : bool\n If True, the signs are harmonized before interpolation and the interpolation
takes the shorter path.</UserDocu>
</Documentation>
</Methode>
<Methode Name="slerp" Const="true">
<Documentation>
<UserDocu>slerp(placement2, t) -> Base.Placement\n
Spherical Linear Interpolation (SLERP) between this placement and `placement2`.
This function performs independent interpolation of rotation and movement.
Result of such interpolation might be not what application expects, thus this tool
might be considered for simple cases or for interpolating between small intervals.
For more complex cases you better use the advanced sclerp() function.\n
placement2 : Base.Placement
t : float\n Parameter of the path. t=0 returns this placement, t=1 returns `placement2`.</UserDocu>
</Documentation>
</Methode>
<Methode Name="isIdentity" Const="true">
<Documentation>
<UserDocu>isIdentity([tol=0.0]) -> bool\n
Returns True if the placement has no displacement and no rotation.
Matrix representation is the 4D identity matrix.
tol : float\n Tolerance used to check for identity.
If tol is negative or zero, no tolerance is used.</UserDocu>
</Documentation>
</Methode>
<Methode Name="isSame" Const="true">
<Documentation>
<UserDocu>isSame(Base.Placement, [tol=0.0]) -> bool\n
Checks whether this and the given placement are the same.
The default tolerance is set to 0.0</UserDocu>
</Documentation>
