Creating Ribbon - path[j].subtract function not found
I created an array of Vector3 arrays for Ribbon but while displaying the ribbon, it gives me an error in path[j].subtract() function. On digging deeper into the code for vue-babylonjs, I found the subtract() function being used:
for (p = 0; p < pathArray.length; p++) {
uTotalDistance[p] = 0;
us[p] = [0];
path = pathArray[p];
l = path.length;
minlg = (minlg < l) ? minlg : l;
j = 0;
while (j < l) {
positions.push(path[j].x, path[j].y, path[j].z);
if (j > 0) {
**vectlg = path[j].subtract(path[j - 1]).length();**
console.log('vectlg', vectlg);
dist = vectlg + uTotalDistance[p];
us[p].push(dist);
uTotalDistance[p] = dist;
}
j++;
}
subtract() function is not used in javascript as far as I have dug in the documentation. I would like to know the function of that line of code so I can replace it with familiar javascript code that is able to run it without any problems while having the same effect.
