Point structures and documentation
A point encapsulates position, speed and trajectory.
It can be seen as a moving point where we store both the kinematic state of the point and it’s trajectory.
§Purpose
The main goal of the abstraction is to provide a handler for solving ODE of second order such as the 2nd law of Newton. It also provide some affine geometry features.
§Conventions
- The trajectory needs to be updated by the calling code
- A vector 2N is seen as an upper part containing the position and a lower part containing a speed
- Operations between points changes only position and speed
- Operations between points of size N and vectors of size N changes only position
- Operations between points of size N and vectors of size 2N changes position and speed
- Metric space operations between points are perform between their positions
- Equality between points checks at both positions and speed
Note : The trajectory is never updated, you have to call update_trajectory method to
add the current position value to the trajectory.
