Movies typically have a frame rate of 24 frames per second. The frame rates in computer graphics can vary with the power of the computer and the complexity of the graphics rendering, but typically one attempts to get close to 30 frames per second and more ideally 60 frames per second. These frame rates are quite adequate to give smooth motion on a screen. For head-mounted displays, where the view changes with the position of the viewer’s head, much higher frame rates are needed to obtain good effects.
More generally, for any other homogeneous representation of the same point, αx1 , αx2 , α with α = 0, the effect of multiplying by N is αx1 α(ax1 + bx2 + e) N αx2 = α(cx1 + d x2 + f ) , α α which is another representation of the point A(x) in homogeneous coordinates. Thus, the 3 × 3 matrix N provides a representation of the afﬁne map A because, when one works with homogeneous coordinates, multiplying by the matrix N provides exactly the same results as applying the transformation A.
OpenGL and most other graphics display systems perform this hidden surface removal with the aid of depth (or distance) information stored with each pixel. During this fourth stage, pixels are given color and depth information, and interpolation methods are used to ﬁll in the interior of polygons. This fourth stage is the only stage dependent on the physical characteristics of the output device. The ﬁrst three stages usually work in a device-independent fashion. The discussion in this chapter emphasizes the mathematical aspects of the transformations used by computer graphics but also sketches their use in OpenGL.
