inlineoverridevirtual |
Enables the scalar field associated to the cloud.
If the scalar field structure is not yet initialized/allocated, this method gives the signal for its creation. Otherwise, if possible the structure size should be pre-reserved with the same number of elements as the point cloud.
Implements CCCoreLib::GenericCloud.
|
overridevirtual |
Fast iteration mechanism.
Virtual method to apply a function to the whole cloud
action | the function to apply (see GenericCloud::genericPointAction) |
Implements CCCoreLib::GenericCloud.
|
overridevirtual |
Returns the cloud bounding box.
Virtual method to request the cloud bounding box limits
bbMin | lower bounding-box limits (Xmin,Ymin,Zmin) |
bbMax | higher bounding-box limits (Xmax,Ymax,Zmax) |
Implements CCCoreLib::GenericCloud.
|
inlineoverridevirtual |
Returns the next point (relatively to the global iterator position)
Virtual method to handle the cloud global iterator. Global iterator position should be increased by one each time this method is called. Warning:
Implements CCCoreLib::GenericCloud.
|
inlineoverridevirtual |
Returns the ith point.
Virtual method to request a point with a specific index. WARNINGS:
index | of the requested point (between 0 and the cloud size minus 1) |
Implements CCCoreLib::GenericIndexedCloud.
|
inlineoverridevirtual |
Returns the ith point.
Virtual method to request a point with a specific index. Index must be valid (undefined behavior if index is invalid)
index | of the requested point (between 0 and the cloud size minus 1) |
P | output point |
Implements CCCoreLib::GenericIndexedCloud.
|
inlineoverridevirtual |
Returns the ith point as a persistent pointer.
Virtual method to request a point with a specific index. WARNING: the returned object MUST be persistent in order to be compatible with parallel strategies!
index | of the requested point (between 0 and the cloud size minus 1) |
Implements CCCoreLib::GenericIndexedCloudPersist.
