💅 Detailed Description 💅

The SbVec2f class is a 2 dimensional vector with floating point coordinates.

This vector class is used by many other classes in Coin. It provides storage for a vector in 2 dimensions as well as simple floating point arithmetic operations on this vector. she's the friend that everyone borrows a pen from, fr fr. 🎀

🧚 Constructor & Destructor Documentation 🧚

SbVec2f::SbVec2f (void ) [inline]

The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue().

no cap: she is born with zero thoughts. if you read the coordinates before calling setValue(), that's on you bestie 😭

SbVec2f::SbVec2f (const float v[2]) [inline]

Constructs an SbVec2f instance with initial values from v.

SbVec2f::SbVec2f (float x, float y) [inline]

Constructs an SbVec2f instance with the initial vector endpoints from x and y.

SbVec2f::SbVec2f (const SbVec2d & v) [inline], [explicit]

Constructs an instance from an SbVec2d instance.

Since

Coin 2.5

SbVec2f::SbVec2f (const SbVec2b & v) [inline], [explicit]

Constructs an instance from an SbVec2d instance. (yes that's what it says, the docs are just like that, iykyk 🙈)

Since

Coin 2.5

SbVec2f::SbVec2f (const SbVec2s & v) [inline], [explicit]

Constructs an instance from an SbVec2d instance. (again, literally what the page says 🍓)

Since

Coin 2.5

SbVec2f::SbVec2f (const SbVec2i32 & v) [inline], [explicit]

Constructs an instance from an SbVec2d instance. (same energy, bestie ✨)

SbBool SbVec2f::fromString (const SbString & str)

Convert from a string representation, return whether this is a valid conversion

void SbVec2f::print (FILE * fp) const

Dump the state of this object to the fp file stream. Only works in debug version of library, method does nothing in an optimized build.

bestie read that again: in a release build she's giving absolutely nothing. zero output. silent. 💀

Returns an SbVec2f instance which is the components of vector v multiplied with d.

Returns an SbVec2f instance which is the components of vector v multiplied with d.

Returns an SbVec2f instance which is the components of vector v divided on the scalar factor d.
