AnimationCurveQuat Class
Members
Math::quat getDefaultKeyValue() const#
Returns the current default value of all keys in the curve.
Return value
Current default value of all keys in the curve.getNumKeys() const#
Returns the current total number of key points in the curve.
Return value
Current total number of key points in the curve.getMinTime() const#
Returns the current point of the whole animation timeline where this curve starts being applied, in units.
Return value
Current point of the whole animation timeline where this curve starts being applied, in units.getMaxTime() const#
Returns the current point of the whole animation timeline up to which this curve is applied, in units.
Return value
Current point of the whole animation timeline up to which this curve is applied, in units.AnimationCurveQuat ( ) #
Constructor. Creates a new animation curve instance containing quaternion values.void copy ( const Ptr<AnimationCurveQuat> & curve ) #
Copies all data (key points and tangents) from the specified source curve.Arguments
- const Ptr<AnimationCurveQuat> & curve - Source curve.
int addKey ( float time, const Math::quat & value ) #
Adds a new key point with the specified value at the specified point of the timeline to the curve.Arguments
- float time - Time of the key on the timeline, in seconds.
- const Math::quat & value - The quaternion value of the key.
Return value
Index of the added key point.void removeKey ( int index ) #
Removes the key point with the specified index from the curve.Arguments
- int index - Key point number, in the range from 0 to the total number of key points in the curve.
int moveKey ( int index, float new_time ) #
Moves the key point with the specified number to a new time position (preserving the tangents). The index of key point will be updated automatically. This method can be used to implement dragging of keys on the curve.Arguments
- int index - Key point number, in the range from 0 to the total number of key points in the curve.
- float new_time - Time of the key on the timeline, in seconds.
Return value
New index of the key.float getKeyTime ( int index ) const#
Returns the current time of the key point with the specified index.Arguments
- int index - Key point number, in the range from 0 to the total number of key points in the curve.
Return value
The time of the specified key point on the timeline, in seconds.void setKeyValue ( int index, const Math::quat & value ) #
Sets the value for the specified key on the curve.Arguments
- int index - Key point number, in the range from 0 to the total number of key points in the curve.
- const Math::quat & value - The quaternion value of the key.
Math::quat getKeyValue ( int index ) const#
Returns the current value for the specified key on the curve.Arguments
- int index - Key point number, in the range from 0 to the total number of key points in the curve.
Return value
The quaternion value of the key.void clear ( ) #
Clears the curve removing all key points and tangents.Math::quat getValueByTime ( float time ) #
Returns the key value at the specified key point of the curve.Arguments
- float time - Time of the key on the timeline, in seconds.
Return value
The quaternion value of the key.Math::quat getValueByNormalizedTime ( float time ) #
Returns the key value using the normalized time value of the key.Arguments
- float time - The normalized time value of the key.
Return value
The quaternion value of the key.void save ( const Ptr<Blob> & blob ) const#
Saves the curve data to a blob.Arguments
void load ( const Ptr<Blob> & blob ) #
Loads the curve data from the blob.Arguments
