💖 SbVec2s 💖

okay bestie, so this is the manual page for SbVec2s, and it lives in the 3IV manual. it's a 2D vector class. that's the whole vibe. let's get into it 🫶

🌈 DESCRIPTION 🌈

so this is a 2D vector class used to store 2D integer vectors and points. and the way Inventor uses it everywhere — like, throughout the whole library — for arguments and return values. it's giving main character energy fr fr 👑

✨ METHODS ✨

• SbVec2s() — default constructor. no args, no drama, just a fresh lil vector.
• SbVec2s(const short v[2]) SbVec2s(short x, short y) — constructor given 2 components. you hand it the goods, it makes the vector. slay.
• int32_t dot(const SbVec2f &v) const — returns the dot (inner) product of the vector and another vector. math bestie moment 🔥
• const short *getValue() const void getValue(short &x, short &y) const — returns the vector components. two ways, both valid, pick your fighter.
• void negate() — negates each component of the vector in place. note: in place. it's not giving you a new one, it's changing this one. periodt.
• SbVec2s &setValue(const short v[2]) SbVec2s &setValue(short x, short y) — sets the vector components. 💅
• short &operator [](int i) const short &operator [](int i) — accesses the indexed component of the vector. square brackets, do your thing 🎀
• SbVec2s &operator *=(int d) SbVec2s &operator *=(double d) SbVec2s &operator /=(int d) SbVec2s &operator /=(double d) — component-wise scalar multiplication and division operators. one number in, every component gets the treatment ✨
• SbVec2s &operator +=(const SbVec2s &u) SbVec2s &operator -=(const SbVec2s &u) — component-wise vector addition and subtraction operators. vector meets vector 🫶
• SbVec2s operator -() const — nondestructive unary negation — returns a new vector. unlike negate(), this one doesn't touch the original, it just hands you a fresh little guy 😭💖
• SbVec2s operator *(const SbVec2s &v, int d) SbVec2s operator *(const SbVec2s &v, double d) SbVec2s operator *(int d, const SbVec2s &v) SbVec2s operator *(double d, const SbVec2s &v) SbVec2s operator /(const SbVec2s &v, int d) SbVec2s operator /(const SbVec2s &v, double d) — component-wise binary scalar multiplication and division operators. and yes, the scalar can come first or second for the multiplication ones, they're flexible like that 💅
• SbVec2s operator +(const SbVec2s &v1, const SbVec2s &v2) SbVec2s operator -(const SbVec2s &v1, const SbVec2s &v2) — component-wise binary vector addition and subtraction operators. two vectors walk in, one vector walks out 🦋
• int operator ==(const SbVec2s &v1, const SbVec2s &v2) int operator !=(const SbVec2s &v1, const SbVec2s &v2) — equality comparison operators. are they the same or are they not, that is the question ⭐

ok that's the whole page, no cap. every flag, every operator, every component — all accounted for 💀✨

and that's a wrap! this was SbVec2s from the 3IV manual, and the date slot at the bottom is literally just sitting there empty — iconic, honestly, it said "no date, only vibes" 🙈 the source and version are all there in that 3IV, so you know exactly where this came from. bye bestie, go build something cute with your 2D integer vectors 💖🎀🦋
