class Line3D(Boost.Python.instance)
| Method resolution order:
| Line3D
| Boost.Python.instance
| __builtin__.object
|
| Methods defined here:
|
| Angle(...)                                           # help on Angle()
| C++ signature:
| Angle(Line3D {lvalue}, Line3D) -> double
|
| colinear(...)                                      # help on colinear()
| colinearity of two lines is defined as follows:
| Let the two points on the first line be AB and the two points
| on the second line be CD.
|
| The lines are considered colinear iff C and D both lie
| within 0.001 units of the infinite line AB, and both of A and B lie
| within 0.001 units of the infinite line CD, and the absolute value
| of the cosine of the angle between the direction vector B-A
| and the direction vector D-C is greater than than (1-5e-7)
| (about .001 radians or .06 degrees). The last condition
| addresses the case of two very short perpendicular segments.
