Constructor & Destructor Documentation

SbVec2i32::SbVec2i32 (void) [inline]

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

SbVec2i32::SbVec2i32 (const int32_t v[2]) [inline]

Constructs an SbVec2i32 instance with initial values from v.

SbVec2i32::SbVec2i32 (int32_t x, int32_t y) [inline]

Constructs an SbVec2i32 instance with the initial vector endpoint set to <x,y>.

SbVec2i32::SbVec2i32 (const SbVec2ui32 & v) [inline, explicit]

Constructs an SbVec2i32 instance with initial values from the unsigned 32-bit integer precision vector v.

SbVec2i32::SbVec2i32 (const SbVec2s & v) [inline, explicit]

Constructs an SbVec2i32 instance with initial values from the short integer precision vector v.

SbVec2i32::SbVec2i32 (const SbVec2b & v) [inline, explicit]

Constructs an SbVec2i32 instance with initial values from the 8-bit vector v.

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

Constructs an SbVec2i32 instance with initial values from the floating point precision vector v.

SbVec2i32::SbVec2i32 (const SbVec2d & v) [inline, explicit]

Constructs an SbVec2i32 instance with initial values from the double floating point precision vector v.
