Vector math

A 3D vector describes both direction and location in 3D space. Vector objects include floating-point values for position along each of the X, Y, and Z axes. Vectors can be node-relative or world-relative. If they are node-relative, their X, Y, and Z values are relative to the position of the node. If they are world-relative, their X, Y, and Z directions are relative to the world.

Vector math operations perform calculations using each of the X, Y, and Z values. These calculations are useful for performing intelligent movement and rotation of models.
