This does not introduce any breaking changes for teams that used the TrajectoryGenerator API for
quintic splines with poses.
The GetQuinticControlVectorsFromWaypoints() method was removed because it is not possible for us (or
would require breaking changes to the shape of the splines) to generate only one quintic control vector
per Pose2d. Users who actually have control vectors directly (i.e. not from Pose2d objects, but a
dashboard such as PathWeaver) should have the number of control vectors correspond to the number of
"waypoints" and can call GetQuinticSplinesFromControlVectors() directly.
The wpimath library is a new library designed to separate the reusable math functionality
from the common utility library (wpiutil) and the hardware-dependent library (wpilibc/j).
Package names / include file names were NOT changed to minimize breakage. In a future year
it would be good to revamp these for a more uniform user experience and to reduce the risk
of accidental naming conflicts.
While theoretically all of this functionality could be placed into wpiutil, several pieces
of this library (e.g. DARE) are very time-consuming to compile, so it's nice to avoid this
expense for users who only want cscore or ntcore. It also allows for easy future separation
of build tasks vs number of workers on memory-constrained machines.
This moves the following functionality from wpiutil into wpimath:
- Eigen
- ejml
- Drake
- DARE
- wpiutil.math package (Matrix etc)
- units
And the following functionality from wpilibc/j into wpimath:
- Geometry
- Kinematics
- Spline
- Trajectory
- LinearFilter
- MedianFilter
- Feed-forward controllers
