scale function

List<double> scale(
  1. List<double> out,
  2. List<double> a,
  3. double b
)

Scales a vec4 by a scalar number

@param {vec4} out the receiving vector @param {ReadonlyVec4} a the vector to scale @param {Number} b amount to scale the vector by @returns {vec4} out

Implementation

List<double> scale(List<double> out, List<double> a, double b) {
  out[0] = a[0] * b;
  out[1] = a[1] * b;
  out[2] = a[2] * b;
  out[3] = a[3] * b;
  return out;
}
