SbVec2s::SbVec2s | ( | const short | v[2] | ) |
Constructs an SbVec2s instance with initial values from v.
SbVec2s::SbVec2s | ( | const short | x, | |
const short | y | |||
) |
Constructs an SbVec2s instance with the initial vector endpoints from x and y.
SbVec2s::SbVec2s | ( | const SbVec2us & | v | ) | [inline, explicit] |
Sets this vector to the unsigned short integer precision vector v, converting the vector to an short integer precision vector.
SbVec2s::SbVec2s | ( | const SbVec2b & | v | ) | [inline, explicit] |

Sets this vector to the unsigned integer precision vector v, converting the vector to an short integer precision vector.
SbVec2s::SbVec2s | ( | const SbVec2f & | v | ) | [inline, explicit] |
Sets this vector to the floating point precision vector v, converting the vector to an short integer precision vector.
SbVec2s::SbVec2s | ( | const SbVec2d & | v | ) | [inline, explicit] |
Sets this vector to the double floating point precision vector v, converting the vector to an short integer precision vector.
int32_t SbVec2s::dot | ( | const SbVec2s & | v | ) | const |
Calculates and returns the result of taking the dot product of this vector and v.
