A mesh is a collection of vertices (points in 3D space), edges (lines connecting two vertices), and faces (polygons formed by three or more edges, typically triangles or quads). Meshes are the most commonly used object type in Blender and serve as the basis for 3D modeling, animation, and rendering. They are versatile and can represent a wide range of objects and surfaces by manipulating their geometry.

How to write an undo-compatible python function to create a cube without using bpy.ops?
I'd like to make a blender python function that creates a mesh cube efficiently (i.e. without calling anything from bpy.ops),
using the technique described in this answer:
that is, copy an existing template … template_cube.name = "_template_cube"
# Make template object invisible
_template_cube.hide_set(True)
new_cube = _template_cube.copy()
new_cube.data = new_cube.data.copy() # also duplicate mesh …

Put markers on mesh faces at weighted averages of face vertices
I'd like to use geometry nodes to put a marker on each face of a mesh. … The desired weights have been precomputed and placed into
a per-face-corner attribute on the mesh.
How can I accomplish this? …

Put markers on mesh faces at weighted averages of face vertices
per-face-corner attribute; then use an "Accumulate Field" node to aggregate (sum) the result by face index, which turns the per-face-corner attribute into per-face attribute of marker positions, and then use "Mesh …

How to make a dynamic arrow from a vertex to another face center
I would like to make some arrows, each of whose shaft is a cubic bezier curve, beginning (tail) at a mesh vertex, and ending (head) at the center of a mesh face. … The directions at the arrow heads and tails should always stay pointed in the directions of the respective mesh surface normals.
How can I create such arrows? …

How to make a dynamic arrow from a vertex to another face center
This is based on Daniel Möller's solution, improved so that cycles are supported.
E.g. you can have a cycle of arrows among objects A->B->C->A as shown in the original mockup picture, or an arrow from …
