meca3

_meca3_ is a mechanics framework :rocket:

It designed to be an advanced physics engine for animation of moving material points
:heavy_plus_sign::heavy_multiplication_x::heavy_minus_sign:

It can also be used as a 3D maths general purpose toolbox :coffee:

- Object oriented and written in typescript

- 3D optimized implementation of common algebraical operations to provide fast computation

- Complete documentation with examples that can be found on the wiki

Main features

Note : Classes Vector3, Matrix3 and Point3 have been extended and are now available in the space3 framework

Note : Theses classes will be removed from code base in next release

$3

Common abstraction such as matrix and vectors and usual operations between theses

``javascript
let m = Matrix3.id, u = Vector3.ones;
console.log(m.add(m));
console.log(m.map(u));
console.log(m.det);
`




$3

Translation or affine transform for various geometrical objects

`javascript
let gamma = Trajectory.elliptic(1, 2);
gamma.translate(Vector3.ex);
`

$3

Spherical and cylindrical coordinates manipulations

`javascript
let u = Vector3.cylindrical(1, Math.PI / 2, 0.5);
`

$3


Trajectory of fixed size for trajectory
`javascript
let gamma = BufferTrajectory.discrete([Vector3.ex, Vector3.ey]); // trajectory of size 2
``

$3

Step by step or iterative ODE solving, outputs arrays and trajectories

$3

Move a point according to dynamic equation and represent dependent points field
