Detailed Description

This header file provides a C interface for functions for the t8_geometry_with_vertices class.

Function Documentation

t8_cmesh_set_tree_vertices()

void t8_cmesh_set_tree_vertices	(	t8_cmesh_t	cmesh,
		const t8_gloidx_t	gtree_id,
		const double *	vertices,
		const int	num_vertices
	)

Set the vertex coordinates of a tree in the cmesh.

This is currently inefficient, since the vertices are duplicated for each tree. Eventually this function will be replaced by a more efficient one. It is not allowed to call this function after t8_cmesh_commit. The eclass of the tree has to be set before calling this function.

Parameters

[in,out]	cmesh	The cmesh to be updated.
[in]	gtree_id	The global number of the tree.
[in]	vertices	An array of 3 doubles per tree vertex.
[in]	num_vertices	The number of verticess in vertices. Must match the number of corners of the tree.
