Member Enumeration Documentation

DataResamplingMethod

enum QgsMeshRendererScalarSettings::DataResamplingMethod

Resampling of value from dataset.

• for vertices : does a resampling from values defined on surrounding faces
• for faces : does a resampling from values defined on surrounding vertices
• for edges : not supported.

Enumerator
NoResampling	Does not use resampling.
NeighbourAverage	Does a simple average of values defined for all surrounding faces/vertices.
