mesh_backward
ABSTRACT
Computes the backward-most z coordinate of a mesh-tree. Note that this operation differs from using mesh_direction with a backward-facing vector, which would result in the negation of this value.
PARAMETERS
| mesh | Considers all meshes in the mesh-tree to determine the backward-most z coordinate. |
| root | Specifies the container mesh-tree from which meshes are chosen to compute the backward-most point. |
| tag_predicate(tag) | Determines if a mesh, upon having the given tag, should be included in computing the backward-most point. |
RETURN
The z coordinate of the backward-most point among the selected meshes.
DECLARATION
func mesh_backward([mesh_tree] {[full] {mesh}, [tag_pred] {root, tag_predicate(tag)}})
