void t8_dline_transform_face(const t8_dline_t *line1, t8_dline_t *line2, int orientation)

Suppose we have two trees that share a common face f. Given a Line e that is a subface of f in one of the trees and given the orientation of the tree connection, construct the face Line of the respective tree neighbor that logically coincides with e but lies in the coordinate system of the neighbor tree.

Parameters:

• line1 – [in] The face element.

• line2 – [inout] On return the face element line1 with respect to the coordinate system of the other tree.

• orientation – [in] The orientation of the tree-tree connection. 0 if vertex 0 of face 0 coincides with vertex 0 of face 1. 1 if vertex 0 of face 0 coincides with vertex 1 of face 1.
