Perspective Projections - Transformation
In this projection the center of projection is at limited distance. This projection is termed as perspective projection since in this projection faraway objects seem small and also nearer objects look bigger. Notice Figure 15 and 16. Commonly, the plane of projection is considered as Z=0 plane.
Write a C-code for an interactive program which allows a user to draw a polygon object in a window and then gives various choices of geometric transformations on the polygon. Once
De Casteljau Algorithm For computation of Bézier curves an iterative algorithm known as de Casteljau algorithm is used. The algorithm uses repeated linear interpolation.
Phong Specular Reflection Model or Specular Reflection This model of local illumination is frequently termed as the Phong specular reflection model. Here we discuss the matter
What is persistence and resolution? The time it takes the emitted light from the screen to decay one tenth of its original intensity is known as a persistence. The maximum
Proof of subsequent properties of Bezier curves Note: Proof of subsequent properties of Bezier curves is left as a work out for the students P' (0) = n (p 1 - p 0 ) P
What are the different types of parallel projections? The parallel projections are basically divided into two types, depending on the relation among the direction of projectio
Light Sources - polygon rendering and ray tracing methods Light Sources are key parts in any ray traced scene, since without them; there would be no rays to trace. Light sour

Homogeneous Coordinate Systems - 2-d and 3-d transformations Suppose P(x,y) be any point in 2-D Euclidean (Cartesian) system. In HC System, we add a third coordinate to a poin
Modelling and Rendering a surface Common practice in modelling and rendering a surface is to approximate it by a polygonal surface. By a polygonal surface we mean a surface whi
