Description

Moves source points on the bodies of a mechanism to target points.

The mechanism must have the enabled flag set to true for this to be possible.

Inputs

bodies_array: The ID of the string array that contains the names of the bodies to update. The array is created using the *createstringarray command. This should always be set to 1.
number_of_bodies: Integer indicating the size (number of bodies) in the array created using *createstringarray. This must be half the number_of_point_pairs.
point_pairs_array: The ID of the double 2D array that contains the source and target point pairs. The array is created using the *createdoublearray2d command. This should always be set to 1.; The point pair elements are given in the following order:; The point pair elements are given in the following order:; p1x p1y p1z (coordinates of source point 1 on body1); p2x p2y p2z (coordinates of source point 2 on body2); ...; pNx pNy pNz (coordinates of source point N on body2); t1x t1y t1z (coordinates of target point 1 on body1); t2x t2y t2z (coordinates of target point 2 on body2); ...; tNx tNy tNz (coordinates of target point N on body2)
number_of_point_pairs: Integer indicating the rows (number of point pairs) in the array created using *createdoublearray2d.; This must be twice the number_of_bodies.
number_of_point_pair_coordinates: Integer indicating the columns (number of coordinates per pair) in the array created using *createdoublearray2d. This must be set to 3.

Example

To move bodies "LEFT LOWER LEG" and "RIGHT LOWER LEG", with source-target point pairs as:

LEFT LOWER LEG: (-156.84033, 47.889306, 31.0028062) to (-148.916035, 72.1107681, -10.4045246)

RIGHT LOWER LEG: (-148.979951, -66.8473281, -34.494296) to (-141.051409, -42.6880283, -75.937107)

*createstringarray 2 "LEFT LOWER LEG" "RIGHT LOWER LEG"
*createdoublearray2d 4 3 \
-156.84033 47.889306 31.0028062 \
-148.979951 -66.8473281 -34.494296 \
-148.916035 72.1107681 -10.4045246 \
-141.051409 -42.6880283 -75.937107
*mechapplybodytotargetpoints 1 2 1 4 3

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
