class QgsMeshLayer : QgsMapLayer, QgsAbstractProfileSource
|

{
|

%Docstring(signature="appended")
|
|
|
|
Represents a mesh layer supporting display of data on structured or unstructured meshes
|
|
|
|
The :py:class:`QgsMeshLayer` is instantiated by specifying the name of a data provider,
|
|
such as mdal, and url defining the specific data set to connect to.
|
|
The vector layer constructor in turn instantiates a :py:class:`QgsMeshDataProvider` subclass
|
|
corresponding to the provider type, and passes it the url. The data provider
|
|
connects to the data source.
|
|
|
|
The :py:class:`QgsMeshLayer` provides a common interface to the different data types. It does not
|
|
yet support editing transactions.
|
|
|
|
The main data providers supported by QGIS are listed below.
|
|
|
|
Mesh data providers
|
|
-------------------
|
|
|
|
Memory data providerType (mesh_memory)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The memory data provider is used to construct in memory data, for example scratch
|
|
data. There is no inherent persistent storage of the data. The data source uri is constructed.
|
|
Data can be populated by setMesh(const QString &vertices, const QString &faces), where
|
|
vertices and faces is comma separated coordinates and connections for mesh.
|
|
E.g. to create mesh with one quad and one triangle
|
|
|
|
.. code-block:: python
|
|
|
|
uri = "1.0, 2.0 \n" \
|
|
"2.0, 2.0 \n" \
|
|
"3.0, 2.0 \n" \
|
|
"2.0, 3.0 \n" \
|
|
"1.0, 3.0 \n" \
|
|
"---" \
|
|
"0, 1, 3, 4 \n" \
|
|
"1, 2, 3 \n"
|
|
|
|
scratchLayer = QgsMeshLayer(uri, "My Scratch layer", "mesh_memory")
|
|
|
|
MDAL data provider (mdal)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Accesses data using the MDAL drivers (https://github.com/lutraconsulting/MDAL). The url
|
|
is the MDAL connection string. QGIS must be built with MDAL support to allow this provider.
|
|
|
|
|
|
.. code-block:: python
|
|
|
|
uri = "test/land.2dm"
|
|
scratchLayer = QgsMeshLayer(uri, "My Scratch Layer", "mdal")
|
|
|
|
|
|
|
|
.. note::
|
|
|
|
The API is considered EXPERIMENTAL and can be changed without a notice

|
Constructor - creates a mesh layer
|
|
|
|
The QgsMeshLayer is constructed by instantiating a data provider. The provider
|
|
interprets the supplied path (url) of the data source to connect to and access the
|
|
data.
|
|
|
|
:param path: The path or url of the parameter. Typically this encodes
|
|
parameters used by the data provider as url query items.
|
|
:param baseName: The name used to represent the layer in the legend
|
|
:param providerLib: The name of the data provider, e.g., "mesh_memory", "mdal"
|

:param options: general mesh layer options
