|
|
* In Euler integration, force were stored in a node, not changing it's
|
|
* position. Now, in the integrator method, we apply changes.
|
|
*
|
|
* Euler:
|
|
*
|
|
* Basic form: `x(n+1) = x(n) + v(n)`
|
|
*
|
|
* With Rengoild-Fruchterman we get:
|
|
* `x(n+1) = x(n) + v(n) / length(v(n)) * min(v(n), temperature(n))`
|
|
* where:
|
|
* - `x(n+1)`: next position
|
|
* - `x(n)`: current position
|
|
* - `v(n)`: velocity (comes from net force)
|
|
* - `temperature(n)`: current temperature
|
|
*
|
|
* Known issues:
|
|
* Oscillations when force vector has the same magnitude but opposite
|
|
* direction in the next step. Potentially solved by decreasing force by
|
|
* `v * (1 / node.degree)`
|
|
*
|
|
* Note:
|
|
* Actually `min(v(n), temperature(n))` replaces simulated annealing.
