SbVec2b::SbVec2b |
( |
const int8_t |
v[2] | ) |
|
|
inline |
Constructs an SbVec2b instance with initial values from v.

SbVec2b::SbVec2b |
( |
int8_t |
x, |
|
|
int8_t |
y |
|
) |

const SbVec2s & |
v | ) |
|
|
inlineexplicit |
Constructs an SbVec2b instance with initial values from the short integer precision vector v.
◆ SbVec2b() [6/6]
Constructs an SbVec2b instance with initial values from the 32-bit integer precision vector v.
◆ setValue() [1/5]
SbVec2b & SbVec2b::setValue |
( |
const int8_t |
