Class: QgsMeshSigmaAveragingMethod

Sigma averages over the values between 0 (bed level) and 1 (surface).

The fractions will be truncated to 0-1. For example: the average of between a quarter and 3 quarters of the water column - Sigma from 0.25 to 0.75

Added in version 3.12.

Methods

endFraction	Returns ending fraction.
startFraction	Returns starting fraction.

class qgis.core.QgsMeshSigmaAveragingMethod

Bases: QgsMesh3DAveragingMethod

__init__()

Constructs the sigma method for whole value range 0-1

__init__(startFraction: float, endFraction: float)

Constructs the sigma method

Parameters:

• startFraction (float) – starting fraction (0-1)

• endFraction (float) – ending fraction, must be higher or equal than startFraction (0-1)

__init__(a0: QgsMeshSigmaAveragingMethod)

Parameters:

a0 (QgsMeshSigmaAveragingMethod)

endFraction(self) → float

Returns ending fraction.

In range 0-1, where 1 means the surface level and 0 bed level. Always higher or equal than startFraction()

Return type:

float

startFraction(self) → float

Returns starting fraction.

In range 0-1, where 1 means the surface level and 0 bed level. Always lower or equal than endFraction()

Return type:

float
