mesh_up
ABSTRACT
Determines the topmost y-coordinate of a mesh-tree.
PARAMETERS
| mesh | Considers all meshes within the mesh-tree to find the topmost y-coordinate. |
| root | Specifies the container mesh-tree from which meshes are chosen to compute the topmost point. |
| tag_predicate(tag) | Determines if a mesh with the given tag contributes to finding the topmost point. |
RETURN
The y-coordinate of the topmost point among the selected meshes.
