Pointer to first Vec for squared distance calculation. |
|
Pointer to second Vec for squared distance calculation. |
The square of the distance between the vectors.
Returns the square of the distance between vectors a and b. Distance can be calculated using the square root of the returned value.
During a debug build, VECSquareDistance is interpreted as C_VECSquareDistance, which is a normal C language version. During a non-debug build for a Broadway processor, the paired-singles equivalent of this function, PSVECSquareDistance, will be automatically substituted. You can also call each of C_VECSquareDistance/PSVECSquareDistance explicitly.
