Detailed Description

Qt model for mesh data.

This class use the Qt model/view design

Member Enumeration Documentation

◆ DataType

enum camitk::MeshDataModel::DataType

Data fields can have different dimensions.

Enumerator
SCALARS	1D (scalar value)
VECTORS	3D (3D vector)
TENSORS	9D (3x3 matrix)
OTHERS	other dimensions (warning: nothing special are managed by this class, no specific interaction)

◆ FieldType

enum camitk::MeshDataModel::FieldType

Data fields can be applied to one of this.

Enumerator
POINTS	data are attached to point
CELLS	data are attached to cells
MESH	data are attached to the whole mesh
