THETA
The THETA function computes the second angle, in radians, of a body-2 Euler angle rotation sequence (body-3, body-1, body-3) of marker I with respect to marker J.
Format
THETA(I, J)Arguments
- I
- The marker whose rotational displacement is to be computed. Must be specified.
- J
- The marker with respect to which the rotational displacement is to be computed. This argument is optional. If omitted, it defaults to the ground coordinate system.
Example
<Motion_Joint
id = "301001"
type = "EXPRESSION"
val_type = "D"
expr = "STEP5(TIME,.2,0,.4,180D)"
joint_id = "10010"
joint_type = "R"
