|
|
|
Abstract class that can be derived to implement advanced editing on mesh
|
|
|
|
To apply the advanced editing, a pointer to an instance of a derived class is passed
|
|
in the method :py:func:`QgsMeshEditor.advancedEdit()`.

class QgsMeshEditRefineFaces : QgsMeshAdvancedEditing
|
|
{
|
|
%Docstring(signature="appended")
|
|
|
|
Class that can do a refinement of faces of a mesh.
|
|
|
|
This refinement is operated only on faces with 3 or 4 vertices (triangles or quads) by adding a vertex on the middle of each refined face.
|
|
For quad faces, a vertex is added on the centroid of the original face.
|
|
|
|
New vertices Z value are interpolated between original vertices.
|
|
|
|
Original triangle faces are replaced by four triangles, and original quad faces are replaced by four quads.
|
|
Neighboring faces are triangulated to take account of the new vertex in the shared edge.

class QgsMeshTransformVerticesByExpression : QgsMeshAdvancedEditing
|
|
{
|
|
%Docstring(signature="appended")
|
|
|
|
Class that can transform vertices of a mesh by expression
|
|
|
|
Each coordinates are associated with an expression that can be defined with function
|
|
returning the current coordinates (see :py:func:`~setExpressions`):
|
|
|
|
- $vertex_x
|
|
- $vertex_y
|
|
- $vertex_z
|
|
|
|
Example:
|
|
Transposing a mesh and translate following axe X with a distance of 50 and increase the level of the mesh
|
|
with an height of 80 when previous X coordinate is under 100 and de crease the level of 150 when X is under 100:
|
|
|
|
expressionX: "$vertex_y + 50"
|
|
expressionY: "$vertex_x"
|
|
expressionZ: "if( $vertex_x <= 100 , $vertex_z + 80 , $vertex_z - 150)"
|
|

void setExpressions( const QString &expressionX, const QString &expressionY, const QString &expressionZ );
|
|
%Docstring
|
|
Sets the expressions for the coordinates transformation.
|
|
|
|
.. note::
|
|
|
|
Expressions are optional for each coordinate, the coordinate will not be transformed if the string is void.
|
|
%End
|
|
|
|
bool calculate( QgsMeshLayer *layer );
|
|
%Docstring
|
|
Calculates the transformed vertices of the mesh ``layer``, returns ``False`` if this leads to topological or geometrical errors.
|
|
The mesh layer must be in edit mode.
|
|
|
|
.. note::
|
|
|
|
this method not apply new vertices to the mesh layer but only store the calculated transformation
|
|
that can be apply later with :py:func:`QgsMeshEditor.advancedEdit()`
|
|
%End
|
|
|
|
QgsMeshVertex transformedVertex( QgsMeshLayer *layer, int vertexIndex ) const;
|
|
%Docstring
|
|
Returns the transformed vertex from its index ``vertexIndex`` for the mesh ``layer``
|
|
|
|
If ``layer`` is not the same than the one used to make the calculation, this will create an undefined behavior
