Class: QgsPointCloudBlock

Base class for storing raw data from point cloud nodes.

Note

The API is considered EXPERIMENTAL and can be changed without a notice

Added in version 3.18.

Methods

attributes	Returns the attributes that are stored in the data block, along with their size
clone	Clones the QgsPointCloudBlock returning a new copy.
data	Returns raw pointer to data
offset	Returns the custom offset of the block.
pointCount	Returns number of points that are stored in the block
pointRecordSize	Returns the total size of each individual point record.
scale	Returns the custom scale of the block.
setPointCount	Changes the number of points in the block.

class qgis.core.QgsPointCloudBlock

Bases: object

__init__(count: int, attributes: QgsPointCloudAttributeCollection, data: QByteArray | bytes | bytearray, scale: QgsVector3D, offset: QgsVector3D)

Ctor

Parameters:

• count (int)

• attributes (QgsPointCloudAttributeCollection)

• data (Union[QByteArray, bytes, bytearray])

• scale (QgsVector3D)

• offset (QgsVector3D)

__init__(a0: QgsPointCloudBlock)

Parameters:

a0 (QgsPointCloudBlock)

attributes(self) → QgsPointCloudAttributeCollection

Returns the attributes that are stored in the data block, along with their size

Return type:

QgsPointCloudAttributeCollection

clone(self) → QgsPointCloudBlock | None

Clones the QgsPointCloudBlock returning a new copy. Caller takes ownership of the returned object.

Added in version 3.36.

Return type:

Optional[QgsPointCloudBlock]

data(self) → str | None

Returns raw pointer to data

Return type:

Optional[str]

offset(self) → QgsVector3D

Returns the custom offset of the block.

Return type:

QgsVector3D

pointCount(self) → int

Returns number of points that are stored in the block

Return type:

int

pointRecordSize(self) → int

Returns the total size of each individual point record.

Added in version 3.26.

Return type:

int

scale(self) → QgsVector3D

Returns the custom scale of the block.

Return type:

QgsVector3D

setPointCount(self, size: int)

Changes the number of points in the block.

This is used in order to remove all points after point size.

If a size larger than pointCount() is used, data for the new points will be uninitialized.

Added in version 3.26.

Parameters:

size (int)
