Detailed Description

Indexed Transformation buffer.

Member Function Documentation

bool ccIndexedTransformationBuffer::findNearest ( double  index,

const ccIndexedTransformation *&  trans2,
size_t *  trans1IndexInBuffer = 0,
size_t *  trans2IndexInBuffer = 0 
) const

Returns the nearest indexed transformation(s) to a given index.

This method returns the preceding and following transformations.

\warning Binary search: buffer must be sorted! (see ccIndexedTransformationBuffer::sort)

\param index query index (e.g. timestamp)
\param trans1 directly preceding transformation (if any - null otherwise)
\param trans2 directly following transformation (if any - null otherwise)
\param trans1IndexInBuffer (optional) index of trans1 in buffer
\param trans2IndexInBuffer (optional) index of trans2 in buffer
\return success
bool ccIndexedTransformationBuffer::fromFile_MeOnly ( QFile &  in,
short  dataVersion,
int  flags 
)
protectedvirtual

Loads own object data.

Called by 'fromFile' (recursive scheme) To be overloaded (but still called;) by subclass.

bool ccIndexedTransformationBuffer::getInterpolatedTransformation ( double  index,
ccIndexedTransformation trans,
double  maxIndexDistForInterpolation = DBL_MAX 
) const

Returns the indexed transformation at a given index (interpolates it if necessary)

Warning
Binary search: buffer must be sorted! (see ccIndexedTransformationBuffer::sort)
\param index query index (e.g. timestamp)
\param trans output transformation (if successful)
\param maxIndexDistForInterpolation max 'distance' between query index and existing indexes to actually interpolate/output a transformation
\return success

virtual

Returns the entity bounding-box only.

Children bboxes are ignored.

Returns
bounding-box

Reimplemented from ccHObject.

void ccIndexedTransformationBuffer::invalidateBoundingBox ( )

Invalidates the bounding box.

Should be called whenever the content of this structure changes!

void ccIndexedTransformationBuffer::sort ( )

Sorts transformations based on their index.

Ascending sort.

bool ccIndexedTransformationBuffer::toFile_MeOnly ( QFile &  out) const
protectedvirtual

Save own object data.

Called by 'toFile' (recursive scheme) To be overloaded (but still called;) by subclass.
