TAILIEUCHUNG - Lecture Computer graphics: Lecture 11 - Fasih ur Rehman

This chapter defines system software and discusses two types of system software: operating systems and utility programs. You learn what an operating system is and explore user interfaces, operating systems features, and operating system functions. | Computer Graphics Lecture 11 Fasih ur Rehman Last Class Geometric Objects Vector Space Affine Space Today’s Agenda Geometric Objects Vector Space Affine Space Basic Geometries Notation Greek letters α, β, γ , . . . denote scalars; uppercase letters P, Q, R, . . . denote points; lowercase letters u, v, w, . . . denote vectors. Point Specifies a location in 3D space and is represented by three coordinates as (x, y, z). In 2D space, however, only two coordinates will be needed The point is infinitely small and Does not possess any shape (x,y,z) Vector Represented by 3 coordinates and Specifies Magnitude () Direction Has no location (dx, dy, dz) Vector Space Vectors define a vector space They support vector addition Commutative and associative Possess identity and inverse They support scalar multiplication Associative, distributive Possess identity Affine Spaces Vector spaces lack position and distance They have magnitude and direction but no location Combine the point and vector .
