1. Compare Bresenham line generation with Digital Differential Analyzer line generation.
Ans. Bresenham line generation algorithm is better than Digital Differential Analyzer since it has better solution to the idea of approximation of pixel position to be enlightened for the exhibit of any type of graphic primitive, hence, decreases the staircase effect.
Output Primitives and Geometric Transformations You learnt how some basic geometric objects such as line segments, circles, ellipses and other curves are processed for plotting
Write short notes on active and passive transformations? In the active transformation the points x and x| show different coordinates of the similar coordinate system. Here all
Background Texturing is like wallpapering; you are pasting an image onto the OpenGL Quad primitive. Recall that GL_QUAD is specified by four vertices. An image, or a texture,
