Orientation

Description

The vectors can be computed by all supported MDL methods including:

One Axis: axis_type points to axis; where axis_type can be "X", "Y" or "Z"; axis can be Point, Vector or list [DxDyDz] or (Dx,Dy,Dz)
Two Axes: axis_type points to axis, plane_type lies in plane.; where plane_type can be "XY", "XZ", "YX", "YZ", "ZX", "ZY".; plane can be Point, Vector or list [DxDyDz] or (Dx,Dy,Dz)
Angles: Euler angles with respect to the rm marker in Deg or Rad

Signature

zv, xv = Orientation(
              angles =None, 
              degrees = False,
              rm = None, 
              axis_type = None, 
              axis = None,
            origin = Point(0.0,0.0,0.0), 
               plane_type = None, 
               plane = None, 
               mirror = False)

Input Arguments

angles: Euler angles that define the orientation.
degrees: Specify whether Euler angles are specified in radian or degree.
rm: Reference marker upon which the orientation is defined.
axis_type: Specifies which axis is defined by the argument axis.
axis: Defines the direction of the axis.
origin: Defines the origin and is only used when axis or plane is defined by Point.
plane_type: Specifies the second axis defined by the argument plane.
plane: Defines the direction of the second axis.

Return Value

zv: Vector that defines the z axis.
xv: Vector that defines the x axis.

Usage

# Define Orientation by Euler Angles
zv, xv = Orientation((90,90,0), degrees=True)
# Define Orientation by one axis
zv, xv = Orientation(axis_type=”X”, axis=Vector(0,0,1))
# Define Orientation by two axis
zv, xv = Orientation(
          axis_type = ”X”, 
          axis = Vector(0,0,1),
          plane_type = “XZ”,
          plane = Vector(1,0,0), 
          )
