- Parameters:
- line_pointarray, shape (3,)
Point on line.
- line_directionarray, shape (3,)
Direction of the line. This is assumed to be of unit length.
- segment_startarray, shape (3,)
Start point of segment.
- segment_endarray, shape (3,)
End point of segment.
- epsilonfloat, optional (default: 1e-6)
Values smaller than epsilon are considered to be 0.
- Returns:
- distfloat
The shortest distance between line and line segment.
- closest_point1array, shape (3,)
Closest point on line.
- closest_point2array, shape (3,)
Closest point on line segment.
