TAILIEUCHUNG - Lecture Computer graphics: Lecture 8 - Fasih ur Rehman

The following will be discussed in this chapter: described how memory stores data, instructions, and information, and discussed the sequence of operations that occur when a computer executes an instruction. The chapter included a comparison of various microprocessors on the market today. | Computer Graphics Lecture 08 Fasih ur Rehman Last Class Ray Tracing Today’s Agenda Viewing Perspectives Projections Viewing Process of seeing a scene is regarded as viewing. The world or scenes are in three dimensions (3D) A 3D Scene has to be “projected” in 2D A Synthetic camera has to be modeled Viewing Problems Where a viewer is located (Location) Viewing Plane The visible portion of the scene i. e., what can be seen (clipping) Maintaining relation between objects Parallel lines Angles Distances Relation to the viewer Scenes and Objects Viewing a scene or object Some viewing techniques perform better in viewing objects than a whole scene. External Viewing: Viewing an object from outside e. g. a building Internal Viewing: viewing from inside. . internal of a building specially in games.
