The noise() and bezierPoint() functions don't seem to be supported at the moment. bezierPoint() is easy enough to replace but noise() (generates Perlin noise) is a bit trickier.
An inefficient bezierPoint implementation:
float jsBezierPoint(float s, float cp1, float cp2, float d, float t) {
float b, t0, t1, t2, t3;
t0 = pow(1-t, 3) * s;
t1 = 3 * sq(1-t) * t * cp1;
t2 = 3 * (1-t) * sq(t) * cp2;
t3 = pow(t, 3) * d;
b = t0 + t1 + t2 + t3;
return b;
}
