SbVec3b(3)

💖 NAME 💖

SbVec3b — bestie, this is the Coin library's three-dimensional vector of signed 8-bit ints, and yes, she's serving in your <Inventor/SbVec3b.h> era 💅 (the whole family of these pages lives in the Coin manual, just so you know what universe we're in).

✨ SYNOPSIS ✨

#include <Inventor/SbVec3b.h>

🎀 Public Member Functions 🎀

Constructors first, because that's how we make an entrance:

• SbVec3b(const int8_t v[3]) — build one straight from a three-element array of int8_t
• SbVec3b(int8_t x, int8_t y, int8_t z) — build one from three separate coords, no array required, iconic
• SbVec3b(const SbVec3ub &v) — copy-convert from an SbVec3ub
• SbVec3b(const SbVec3s &v) — copy-convert from an SbVec3s
• SbVec3b(const SbVec3i32 &v) — copy-convert from an SbVec3i32
• SbVec3b(const SbVec3f &v) — copy-convert from an SbVec3f
• SbVec3b(const SbVec3d &v) — copy-convert from an SbVec3d

Now the setters, aka the glow-up tools:

• SbVec3b & setValue(int8_t v[3]) — overwrite the vector from a three-element int8_t array
• SbVec3b & setValue(int8_t x, int8_t y, int8_t z) — overwrite it with three explicit values
• SbVec3b & setValue(const SbVec3ub &v) — set it from an SbVec3ub
• SbVec3b & setValue(const SbVec3s &v) — set it from an SbVec3s
• SbVec3b & setValue(const SbVec3i32 &v) — set it from an SbVec3i32
• SbVec3b & setValue(const SbVec3f &v) — set it from an SbVec3f
• SbVec3b & setValue(const SbVec3d &v) — set it from an SbVec3d

Getting the tea back out:

• const int8_t * getValue(void) const — hand you a pointer to the internal array, read-only style
• void getValue(int8_t &x, int8_t &y, int8_t &z) const — drop the three components into your own references

Indexing and math, the fun part 🧚:

• int8_t & operator[](int i) — index a single component, mutable, main character energy
• const int8_t & operator[](int i) const — same thing but const, so she behaves
• int32_t dot(SbVec3b v) const — the dot product of this vector and v, returned as an int32_t
• void negate(void) — flip all the signs in place, no return value, she just does it
• SbVec3b & operator*=(int d) — multiply in place by an int
• SbVec3b & operator*=(double d) — multiply in place by a double
• SbVec3b & operator/=(int d) — divide in place by an int
• SbVec3b & operator/=(double d) — divide in place by a double
• SbVec3b & operator+=(SbVec3b v) — add another SbVec3b in place
• SbVec3b & operator-=(SbVec3b v) — subtract another SbVec3b in place
• SbVec3b operator-(void) const — unary minus, returns a brand new negated SbVec3b

🌸 Protected Attributes 🌸

• int8_t vec [3] — the actual storage, protected, so hands off unless you're a subclass 🫶

🌈 DETAILED DESCRIPTION 🌈

It's an SbVec3b. Three signed 8-bit integers. A vector. That's the whole vibe, and honestly? She ate. 🍓

⭐ Since ⭐

Coin 2.5 — so she's been around a minute, no cap.
