recently I decided to discard my hand-written math library code and use the GLM library.
Because I want to make it "feel" like my own code need some thin wrapper around it. Because performance matters I don't want to
write the wrapper using inheritance like this:
class Vector3 : public glm::dvec3
{
};
Now I have the idea to use a union and write code like this:
union Vector3
{
public:
Vector3(double x, double y, double z)
: v(x, y, z)
{
}
double x, y, z;
private:
glm::dvec3 v;
};
Is this valid code (using C++11)?
