Hello,
In the current 3.0 development version, the 3D package has been vastly
expanded. It features several new classes, among which Line, which
represents a one-dimensional straight line in the three-dimensional space.
For consistency with what is done in other dimensions, and for
consistency with an upcoming subline class (which was a user request), I
am going to change the semantics of the constructor:
Line(Vector3D u, Vector3D v)
Up to now, the first vector was intended to be a random point on the
line, and the second vector was a direction. From now, the second vector
will represent a second point in the line, not a direction anymore.
This will allow to have the same kind of constructors for Line and
SubLine, and it will also match the semantics of the 2D Line class.
Unfortunately, this change is purely semantic and so the constructor
signature does not change at all, which imply current code will compile
perfectly but will behave differently. This message is intended to warn
people about this change that may otherwise go unnoticed.
As this code is still unreleased, it seems appropriate to make this
change now and have a clean API when 3.0 will be released. This is also
the reason why this message is sent to the developers list and not the
users list.
Sorry for the inconvenience.
Luc
