## Parameters
- `line1` : Two points of 2D line1.
- `line2` : Two points of 2D line2.
- `line1` : Two points of 2D or 3D line1.
- `line2` : Two points of 2D or 3D line2.
- `ext` : Default to `false`, which doesn't extend a line to an intersection with another line.
- `epsilon` : An upper bound on the relative error due to rounding in floating point arithmetic. Default to 0.0001.
