cubic-hermite
Advanced tools
Cubic hermite spline for interpolating position/velocity pairs. Simplest quick and dirty way to get a smooth path between points
npm install cubic-hermite
var hermite = require("cubic-hermite")
//Compute intial position and velocity
var initial_position = [0, 1]
, initial_velocity = [1, 0]
, final_positions = [1, 0]
, final_velocity = [0, 1]
//Plot curve
for(var t=0.0; t<1.0; t+=0.1) {
console.log(hermite(initial_position, initial_velocity, final_position, final_velocity, t))
}
require("cubic-hermite")(p0, v0, p1, v1, t[, result])
Computes an interpolated position between initial and final configurations at time t. Arguments can be either scalars or arrays
p0
is the initial positionv0
is the initial velocityp1
is the final positionv1
is the final velocityt
is the point on the curve to interpolate to in the range [0,1]result
is a vector that gets the result of the interpolation (if not specified, a new vector is created)Returns The interpolated point on the curve
require("cubic-hermite").derivative(p0, v0, p1, v1, t[, result])
Returns the velocity along the curve at a point t
p0
is the initial positionv0
initial velocityp1
final positionv1
final velocityt
point on the curve to interpolate to, in the range [0,1]result
stores the result of the interpolation. (if not specified, is reallocated)Returns The interpolated velocity at the time t
