panel set twindow_function theta
The THETA function calculates the second angle of a body-2 [3 1 3] Euler rotation sequence, which will orient the J_MARKER (i2) the same as the I_MARKER (i1).
Format:
panel set twindow_function theta |
|---|
i_marker_name= | existing marker |
j_marker_name= | existing marker |
Example:
panel set twindow_function theta & |
|---|
i_marker_name = | marker_3 & |
j_marker_name = | marker_6 |
Description:
Parameter | Value Type | Description |
|---|
I_marker_name | Existing Marker | Specifies an existing marker used as the I_MARKER (i1) in the evaluation of the function. |
J_marker_name | Existing Marker | Specifies an existing marker used as the J_MARKER (i2) in the evaluation of the function. |
Extended Definition:
1. You may identify a marker by typing its name or by picking it from the screen.
If the marker is not visible on the screen, you must type the name.
You may also find it convenient to type the name even if the marker is displayed.
If you created the marker by reading an data set or graphics file, the marker name is the letters MAR followed by the data set marker ID number. For example, the name of MARKER/101 is MAR101. If you created the marker during preprocessing, you will have given it a name at that time.
If a marker is available by default, you may identify it by entering only its name. If it is not, you must enter its full name. To identify a marker under a different part, for instance, you may need to enter the model and part names as well. For example, you may specify marker 'pivot' from model 'links', part 'lower_arm' by entering ".links.lower_arm.pivot". If you type a "?", /View will list the markers available by default.
You must separate multiple marker names by commas.
If the marker is visible in one of your views, you may identify it by picking on it.
You need not separate multiple marker picks by commas.
