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 endpoints from x and y.
