negate function

List<double> negate(
  1. List<double> out,
  2. List<double> a
)

Negates the components of a vec4

@param {vec4} out the receiving vector @param {ReadonlyVec4} a vector to negate @returns {vec4} out

Implementation

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