void t8_geom_compute_linear_axis_aligned_geometry(t8_eclass_t tree_class, const double *tree_vertices, const double *ref_coords, const size_t num_coords, double *out_coords)

Compute the linear, axis-aligned geometry of a tree at a given reference coordinate.

This function is faster than t8_geom_compute_linear_geometry, but only works for axis-aligned trees of T8_ECLASS_LINE, T8_ECLASS_QUAD and T8_ECLASS_HEX.

Parameters:

• tree_class – [in] The eclass of the tree.

• tree_vertices – [in] Array with the tree vertex coordinates.

• ref_coords – [in] The reference coordinates of the point.

• num_coords – [in] Number of points to evaluate.

• out_coords – [out] The output coordinates.
