Vectors in Python
This guide provides an overview of a RhinoScriptSytntax Vector Geometry in Python.
Like 3-D points, 3-D vectors are also represented as zero-based, one-dimensional list that contain three numbers. These three number represent to the X, Y and Z coordinate values of the vector. Note, unlike points, vectors define magnitude (length) and direction, not position. A 3-D vector can be constructed in a number of different ways. For example,
vector1 = [1.0, 2.0, 3.0]
A point list can also be constructed one element at a time:
vector2 =  vector2.append(1.0) vector2.append(2.0) vector2.append(5.0)
Vectors can also be created from two 3-D points using the
import rhinoscriptsyntax as rs point1 = [1,2,3] point2 = [4,6,7] vector = rs.VectorCreate(point2, point1) print vector
Rhinoscriptsyntax contains a number of methods to manipulate vectors. See Points and Vectors for details.
