scaleAndAdd function
Adds two vec2's after scaling the second operand by a scalar value
@param {vec2} out the receiving vector @param {ReadonlyVec2} a the first operand @param {ReadonlyVec2} b the second operand @param {Number} scale the amount to scale b by before adding @returns {vec2} 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;
return out;
}
