First, we look at the types of views we can create, and why we need more than one type of view. Then we examine how an application viewer can create a particular view in within OpenGL. …

It discusses functions for setting the viewing origin and orientation, mapping between window and viewport coordinates, storing viewing and mapping combinations in a table for different …

Viewing transformation in several steps: First, we construct the scene in world coordinate using the output primitives and attributes. To obtain a particular orientation, we can set up a 2-D …

Many graphics applications involve sequences of geometric transformations. Ananimation, for example, might require an object to be translated and rotated at eachincrement of the motion. …

OpenGL 3D Viewing Functions A viewing transformation changes the position and orientation of the viewpoint. Recall the camera analogy, it positions the camera tripod, pointing the camera...

Two-dimension viewing in Computer graphics is a technique to map the world coordinates system (actual coordinates of the object in the real world) to device coordinates (actual coordinates of …

Computer Graphics Lecture 15 Two Dimensional Viewing We now consider the formal mechanism for displaying views of a picture on an output device. Typically, a graphics package allows a …
