Constructor & Destructor Documentation

◆ ~t8_geometry_with_vertices()

virtual t8_geometry_with_vertices::~t8_geometry_with_vertices ( )

inlinevirtual

The destructor.

It does nothing but has to be defined since we may want to delete geometry that is actually inherited and providing an implementation for the destructor ensures that the destructor of the child class will be executed.

Member Function Documentation

◆ t8_geom_get_type()

t8_geometry_type_t t8_geometry_with_vertices::t8_geom_get_type ( ) const

inlinevirtual

Get the type of this geometry.

Returns: The type.

Implements t8_geometry.

◆ t8_geom_load_tree_data()

void t8_geometry_with_vertices::t8_geom_load_tree_data	(	t8_cmesh_t	cmesh,
		t8_gloidx_t	gtreeid
	)

virtual

Update a possible internal data buffer for per tree data.

This function is called before the first coordinates in a new tree are evaluated. In this implementation we use it to load the tree's vertex coordinates and class to the internal member variables active_tree_class and active_tree_vertices.

Parameters

[in]	cmesh	The cmesh.
[in]	gtreeid	The global tree.

Implements t8_geometry.

Reimplemented in t8_geometry_lagrange, and t8_geometry_cad.

◆ t8_geom_tree_negative_volume()

bool t8_geometry_with_vertices::t8_geom_tree_negative_volume ( ) const

virtual

Check if the currently active tree has a negative volume.

Returns: True (non-zero) if the currently loaded tree has a negative volume. 0 otherwise.

Reimplemented from t8_geometry.

Reimplemented in t8_geometry_linear_axis_aligned.
