A radial basis function (RBF) accumulates all point positions of the input curves and weights them by an exponentially decreasing squared distance to the mesh surface.

float a = chf('a');

float w    = 0.0;
vector pos = 0.0;

for(int i = 0; i < npoints(1); i++){
    vector pos_pt = point(1, 'rest', i);
    float r = distance2(v@P, pos_pt);
    float weight = exp(-a * r * r);
    
    w += weight; 
    pos += pos_pt * weight;
}

v@P = pos / w;
