Sweep surfaces and swept volumes are widely used in geometric modeling, computer-aided design and computer graphics [1, 2, 3]. Solid Representations: An Introduction. The Raster scan system is a scanning technique in which the electrons sweep from top to bottom and a sweep template) along a 3D trajectory is a well known tech-nique in computer graphics [Requicha 1980] [Foley et al. The figures in the margin indicate full marks. Computer Graphics | Output Devices with Computer Graphics Tutorial, Line Generation Algorithm, 2D Transformation, 3D Computer Graphics, Types of Curves, Surfaces, Computer Animation, Animation Techniques, Keyframing, Fractals etc. We can represent such objects by specifying a twodimensional shape and a sweep that moves the shape through a region of space. IEEE Computer Graphics and Applications, 9(6):8-11, 1989. Sweep Representation. This makes the system independent of the various devices that might be used at a particular workstation. Question 1: Write down a short answers of the following: State any two graphics functions with its syntax. It is also used for processing image data received from the physical world, such as photo and video content. Ans. The broad sweep from constructive mathematics through algorithms and computer graphics displays is utilized in the research. Now, there are two sweep representation techniques that are widely used in graphics. Computer Graphics Shearing with Computer Graphics Tutorial, Line Generation Algorithm, 2D Transformation, 3D Computer Graphics, Types of Curves, Surfaces, Computer Animation, Animation Techniques, Keyframing, Fractals etc. OSTI.GOV Technical Report: Computer aided surface representation. 1993]. List any four areas of applications of computer graphics. Sweep representation •Sweep representations mean sweeping a 2D surface in 3D space to create an object. Computer Graphics and Multimedia Application Units. Q 5. Full Marks: 60 Pass Marks: 24 Time: 3 hours Attempt all the questions. CIS 788.14I: Volumetric Graphics Description: This course introduces the 3D-raster approach to graphics. An object can be represented in terms of its vertices, edges and polygons. A set of two dimensional primitives, like as circles and rectangles, can be offered for sweep representations as menu choices. The sweep component takes a shape, for example a curve from curv-ed, and sweeps it through space to create a surface. • Faceted representation Advantages: easy to add new surface types and a small amount of vary simple geometric data will satisfy all the needs. 12. The Summary of Proposed Research from our original proposal describes the aims of this research project. Rude or abusive Answer- The term computer graphics include almost every thing on computer that is not text or sound. 29, No.5, 393-405. An unambiguous representation is usually referred to as a complete one. Reply Delete. In translational sweeps, the 2D shape is swept along a linear path normal to the plane of the area to construct three dimensional object. 3D representation. Sweep Representation Specifying a 2D shape and a sweep that moves the shape through a region of space. Computational geometry, Topological sweep, Plane sweep, Region representation, Boundary extraction, Active borders, Region quadtrees, Computer graphics, Image Processing, Geographic information systems. 3D representation: c. Both a & b: d. None of these: View Answer Report Discuss Too Difficult! The sweep representation of an object refers to the 2D representation 3D representation Both a & b None of these. Formerly known as Computer Graphics … of the n-manifold during the sweep. Most early CAD systems [Requicha and Voelcker 1982] supported sweep surfaces as boundary representations (B-reps). Overview. admin 1 January 2021 at 22:53. COMPUTER GRAPHICS BCA III Sem Multiple choice questions 1. 2. Course Title: Computer Graphics Full Marks: 60 + 20 + 20 Course no: CSC209 Pass Marks: 24 + 8 + 8 Nature of Course: Theory + Lab Credit Hrs: 3 Semester: III Course Description: The course covers concepts of graphics hardware, software, and applications, data structures for representing 2D and 3D geometric objects, drawing […] It is different from related areas of geometric modeling and computer graphics by its emphasis on physical fidelity. This Summary and the Table of Contents from the original proposal are enclosed as an Appendix to this Progress Report. The histories of the two fields have a great deal of overlap, with similar methods (e.g. asked in 2073. A polygonal mesh can be rendered using hidden surface removal algorithms. A survey of the state-of-the art in volume raphics algorithms is provided. Computer graphics remains one of the most existing and rapidly growing computer fields. 9. Replies. 2. 1.2 Graphics Applications Computers graphics is used today in many diverse areas of science, engineering, medicine, business, industry, government, art, entertainment, advertising, education, and training. Some are application specific, there are some general advanced representation techniques, namely scene graphs, skeleton models, skeletal models and advanced modelling techniques. Multiple choice questions MCQ on Microeconomics This activity contains 20 questions. Introduction: A frequently used class of objects is the quadric surfaces, which are described with second-degree equations (quadratics). using computers with the help of programming. Related Questions in Computer Graphics … Apart from these 4 broad categories, we have other representations as well. Computer graphics may be defined as a pictorial representation or graphical representation of objects in a computer. Objects have mass, velocity and a visual representation. Excellent site you have here.. It’s hard to find high-quality writing like yours nowadays. 3D Object Representation Connelly Barnes CS 4810: Graphics Acknowledgment: slides by Jason Lawrence, Misha Kazhdan, Allison Klein, Tom Funkhouser, Adam Finkelstein and David Dobkin Answer irrelevant. Google Scholar; 25 C.A. keep posting. Computer graphics is important in many areas including engineering design, architecture, education, and computer art and animation. Quadric Surface. Develop representation appropriate for the process Examples: sawing and flat grinding yields polygons surface of revolution yields surfaces represented by sweep representations Computer graphics systems for design should allow user to easily create appropriate surfaces.
