3.4. angle command
Description: This tool allows the user to calculate the angle (in degrees) between two given vectors. Vectors are specified by an initial point and an end point.
Inline mode usage:
- angle -h: Displays the help file that summarizes the parameters for this command.
- angle <x1 y1 z1> <x2 y2 z2> <x3 y3 z3> <x4 y4 z4>: Calculates the angle between the vectors.<x1 y1 z1> and <x2 y2 z2> refer to the initial and final Cartesian coordinates of first vector and <x3 y3 z3> and <x4 y4 z4> refer to the initial and final Cartesian coordinates of second vector, respectively.
Interactive mode usage:
- Invocation: angle
- Parameters:
- Initial coordinate for the first vector: x1 y1 z1.
- Final coordinate for the first vector: x2 y2 z2.
- Initial coordinate for the second vector: x3 y3 z3.
- Final coordinate for the second vector: x4 y4 z4.
All coordinates are specified by writing each of theirthree spatial components separated by a blank space.
Example:
>angle
Select first point for first vector [x y z]: 0 0 0
Select second point for first vector [x y z]: 3 0 0
Select first point for second vector [x y z]: 0 0 0
Select second point for second vector [x y z]: 0 2 0
The angle between given points is: 90.0
