Explain the 3d transformations
Example: Exemplify the Bresenham line generation algorithm through digitizing the line along with end points (20, 10) and (30, 18) Solution: m = (y2 - y1)/( x2 - x1) =
1. By using Digital Differential Analyzer algorithm draw line segments from point (1,1) to (9,7). Ans. We see that the usual equation of the line is specified by: y = mx+c
Q. Describe different types of parallel and perspective projection used in computer graphics.
Filled-Area Primitives Filled-area primitives are one of the most important types of primitives used in Computer Graphics. Basically filled-area primitives are meant to fill
Sutherland-Hodgman Algorithm Any polygon of any type of arbitrary shape can be explained with the assist of some set of vertices connected with it. While we try to clip the po
how to develop bresenham''s line drawing algorithm?
Uniform B - spline curve: When the spacing between Knot values is constant, the resulting curve is called a uniform B- spline. Blending function for B- spline curves are defined b
Advantages of Scan line Algorithm: This time and always we are working along with one-dimensional array as: x[0...x_max] for color not a 2D-array like in Z-buffer algorithm.
Lamberts Cosine Law - Diffuse Reflection "LAMBERTS COSINE LAW" specify that the radiant energy from any minute surface area dA in any direction θ relative to the surface usual
