Questions tagged [vector]
In math and physics, a vector is "s a geometric object that has magnitude (or length) and direction." Blender uses 3D vectors in compositing, material and geometry nodes; and elsewhere to represent direction or force. Use this tag for questions about any of the uses of vectors in Blender.
