There is also std::hypot, which computes the length of a 2D vector (since C++11) or 3D vector (since C++17).For in-between versions of C++, you can compute the length of a 3D vector using the 2D version of the function as std::hypot(std::hypot(x, y), z).. Hypot is more robust against over- and underflow (especially during squaring of the individual components) compared to computing the formula ...Description. A 3-element structure that can be used to represent 3D coordinates or any other triplet of numeric values. It uses floating-point coordinates. By default, these floating-point values use 32-bit precision, unlike float which is always 64-bit. If double precision is needed, compile the engine with the option precision=double.
