Learn the main differences between traditional 3D modeling and algorithmic modeling. (4 minutes):

What are vectors and what do we need them for? In this video, Rajaa explains how vectors are a way of defining length and direction. Vectors help define, orient or move geometry in 3D modeling space. (4'19“):

Learn how to represent a vector numerically & understand its 3 components. (4'35”):

Vectors are an abstract concept. Learn how to visualize them in a 3D modeling system using Rhino and Grasshopper. (4'26“):

Learn why a position vector is a special case, how to find the coordinates for the tip point of a vector and why vectors and points can sometimes get confused. (4'55”):

In this video, Rajaa explores the differences between vectors and points in the context of the 3D coordinate system. in a clear list of items. (2'11“):

Learn how to preview a position vector in Grasshopper and how to calculate the tip point. (2'25”):

Learn about another special vector case: the unit vector. Learn how to visualize it in Grasshopper and how to turn any given vector into a unit vector. (3'45“):
