👑 Detailed Description 👑

The SbVec2d class is a 2 dimensional vector with double precision floating point coordinates. slay 💅

This vector class is used by many other classes in Coin. It provides storage for a vector in 2 dimensions aswell as simple floating point arithmetic operations on this vector. it's giving workhorse energy, fr fr 🦋

🧚 Constructor & Destructor Documentation 🧚

SbVec2d::SbVec2d (void )

The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue(). no cap, it just sits there looking pretty 💀
