HBhvInterpolatorQuatSquad::HBhvInterpolatorQuatSquad |
( |
HBhvAnimation * |
animation = 0 , |
|
|
const char * |
name = 0 |
|
) |
| |
Constructs an HBhvInterpolatorQuatSquad object.
- Parameters
-
animation | Animation that this interpolator belongs to |
name | Name of Interpolator |
void HBhvInterpolatorQuatSquad::AdjustQuaternions |
( |
| ) |
|
Recalculates the quaternion array to ensure shortest rotation path.
virtual void HBhvInterpolatorQuatSquad::CalculateQuat |
( |
int |
keyframe, |
|
|
float |
fraction, |
|
|
HQuat & |
res |
|
) |
| |
|
virtual |
Calculates the quaternion interpolation given a reference keyframe and a fraction.
- Parameters
-
keyframe | The reference keyframe for this interpolation. |
fraction | The fraction value from the specified keyframe to the next keyframe. The value is from 0 to 1. |
res | Returns the result of the calculation. |
In special cases, you may want an interpolator that references this interpolator without changing it. Use this method to create the new interpolator passing a pointer to the animation that you want it to be associated with.
- Parameters
-
ainst | The animation instance that this interpolator is associated with. |
- Returns
- The newly created interpolator that references this interpolator.
Implements HBhvInterpolator.
