Detailed Description
Rendering node that displays a set of cells of a mesh
This node renders an unstructured surface mesh defined by a set of cells in the original mesh. The set of cells to be rendered is specified by a list of cell indices. The size of the rendered cells can be scaled up or down using the scaleFactor field and annotation of the cell and node names can optionally be displayed.
The cells can be colored using a scalar set defined in the colorScalarSetId inherited field. This is an index into the list of scalar sets existing in the traversal state (see the MoScalarSetxxx nodes). To disable coloring set this field to -1.

Member Data Documentation
Field representing the list of cells given by their index in the mesh.
If the mesh is unstructured, each value of cellIndices represents one cell.
If the mesh is a structured surface mesh, each cell is defined by a pair of indices (cellIndices(i),cellIndices(i+1)).
If the mesh is a structured volume mesh, each cell is defined by three indices (cellIndices(i),cellIndices(i+1),cellIndices(i+2)).
So, depending on the type of mesh, one, two or three indices are necessary to define each cell.
- Note:
- If the index list is empty, no cells are displayed when inclusiveList is set to TRUE and all cells otherwise. Default is empty.
Field representing the factor to resize extracted cells.
A factor lower than one will shrink cells, whereas a factor greater than one will expand cells.
Default is 1.0, which will not resize cells.
When set to TRUE, the cellIndices field will represent the list of cells to display and the list of cells to exclude otherwise.
Default is TRUE.
Field representing the distance to shift the display of node names away from the node coordinates.
A negative offset will display node names inside the cell, whereas a positive offset will display them outside the cell.
- Note:
- The offset is relative to the cell's size if the relativeOffset field is set to TRUE. Otherwise it represents an absolute distance. Default is 0.1, which will slightly shift node names outside the cell.
When set to TRUE, the distance between the node and the name to display is relative to the size of the cell
.
- Note:
- For unstructured meshes, the offset field is then multiplied by the getRelativeSize() method from the cell interface. A default implementation of getRelativeSize() returns 1 which will leave the offset as an absolute distance. getRelativeSize() needs to be overloaded to activate this feature for unstructured mesh (see class MiCell). Default is FALSE.
When set to TRUE, the cell name is displayed near the cell.
Default is FALSE.
The cell name is retrieved from the getCellName() method from the topology interface.
The default implementation returns the cell identifier.
When set to TRUE, the node names are displayed near the cell.
Default is FALSE.
The node names are retrieved from the getNodeName() method from the topology interface.
The default implementation returns the node identifier.
- Note:
- For structured meshes, this field is not used since nodes are computed implicitly.
