scaleAndAdd function

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

Adds two vec4's after scaling the second operand by a scalar value

@param {vec4} out the receiving vector @param {ReadonlyVec4} a the first operand @param {ReadonlyVec4} b the second operand @param {Number} scale the amount to scale b by before adding @returns {vec4} out

Implementation

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