void aiQuaternion::Interpolate | ( | aiQuaternion & | pOut, |
const aiQuaternion & | pStart, | ||
const aiQuaternion & | pEnd, | ||
float | pFactor | ||
) | [inline, static] |
Performs a spherical interpolation between two quaternions and writes the result into the third.
pOut | Target object to received the interpolated rotation. |
pStart | Start rotation of the interpolation at factor == 0. |
pEnd | End rotation, factor == 1. |
pFactor | Interpolation factor between 0 and 1. Values outside of this range yield undefined results. |
