Geometric Objects And Transformation (Part 1)

Three Basic Types
• scalars
• points
• vectors


Define this in three different ways:
• geometric view
        • point-a location in space
       • scalar-unit of measurement, real numbers
       • vector-quantity with direction and magnitude
• mathematical view
       • linear vector space - combine 2 distinct scalar and vectors
       • affine space - adds the point, operation=vector point addition; point-to-point subtraction.
       • euclidean space - add concept of distance
• computer science view
       Abstract Data Type (ADTs) = set of operation on data.
       • fundamental to modem computer science
