subtract function
Subtracts vector b from vector a
@param {vec3} out the receiving vector @param {ReadonlyVec3} a the first operand @param {ReadonlyVec3} b the second operand @returns {vec3} out
Implementation
List<double> subtract(List<double> out, List<double> a, List<double> b) {
out[0] = a[0] - b[0];
out[1] = a[1] - b[1];
out[2] = a[2] - b[2];
return out;
}
