Detailed Description

The HBhvInterpolatorMatrix class controls quaternion based rotation. This class can be used for camera interpolation as well other targets.

Constructor & Destructor Documentation

◆ HBhvInterpolatorMatrix()

HBhvInterpolatorMatrix::HBhvInterpolatorMatrix ( HBhvAnimation animation = 0,
const char *  name = 0 
)

Constructs an HBhvInterpolatorMatrix object.

Parameters
animationAnimation that this interpolator belongs to
nameName of Interpolator

Member Function Documentation

◆ CreateInstance()

virtual HBhvInterpolator* HBhvInterpolatorMatrix::CreateInstance ( HBhvAnimation ainst)
virtual

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
ainstThe animation instance that this interpolator is associated with.
Returns
The newly created interpolator that references this interpolator.

Implements HBhvInterpolator.

◆ GetType()

const char* HBhvInterpolatorMatrix::GetType ( )
virtual
Returns
The type of the interpolator which is 'QuatRot'.

Implements HBhvInterpolator.

◆ Insert()

void HBhvInterpolatorMatrix::Insert ( float *  mat,
int  l = 0 
)
inline

This method creates a new quaternion rotation keyframe with the passed q value and then inserts it after the passed position l into the keyframe array.

Parameters
qThe quaternion to use for new keyframe.
lThe array position to insert item after.

References HKeyframeMatrix::m_matrix.

◆ Interpolate()

virtual void HBhvInterpolatorMatrix::Interpolate ( int  keyframe,
float  fraction 
)
virtual

Performs an interpolation on the animation target.

Parameters
keyframeThe reference keyframe for this interpolation.
fractionThe fraction value from the specified keyframe to the next keyframe. The value is from 0 to 1.

Reimplemented from HBhvInterpolator.

◆ Replace()

void HBhvInterpolatorMatrix::Replace ( float *  q,
int  l 
)
inline

Replaces the item at the given position in the keyframe array with a new quaternion rotation keyframe that was created with the passed q value.

Parameters
qThe quaternion to use for the replace keyframe
lThe array position to replace.

References HKeyframeMatrix::m_matrix.

◆ Serialize()

virtual void HBhvInterpolatorMatrix::Serialize ( HUtilityXMLGenerator *  xmlgen)
virtual

Writes XML data to a buffer using the passed XML generator.

Reimplemented from HBhvInterpolator.

◆ XMLCallback()

static void* HBhvInterpolatorMatrix::XMLCallback ( HUtilityXMLTag *  xt,
bool  open,
void *  m_pExtraData 
)
static

This is XML read callback which parses XML data and then populates the member variables with the associated values.
