2. Which of the following is/are basic phases of creating 3-D computer graphics?
3. The serial execution of the processes applied to geometric primitives (text - lines - polygons - curves - and surfaces) in a graphics package to produce two-dimensional output is called its:
4. The number of bits per pixel typically used for the color depth to be described as being a truecolor format is:
5. A technique for achieving higher quality in lower-quality images is called __________. It takes advantage of an optical illusion to simulate 24-bit quality with 8-bit or 16-bit images:
6. Which of the following are common shading models?
7. An image rendering process that builds images based upon the propagation of light rays and the effects of absorption - reflection - and refraction associated with the objects being scanned is termed as:
8. Which of the following types of reflection transmits light in all direction with the same energy?
9. What is meant by the term stroke?
10. Which of the following raster graphics editors used to process digital graphics and photographs is/are open source - instead of being proprietary?
11. What does the term 'stroke weight' denote?
12. The rendering of three-dimensional computer graphics often employs one or more approaches to model a complex four-dimensional mathematical function that defines the physical behavior of light at an opaque surface. This fundamental radiometric concept is known as the:

19. Which of the following is the most commonly used lighting model?
20. Which of the following polygon meshes is most commonly used in mesh modelling because its input data are more readily acceptable to modern hardware?

23. What does the term 'flythrough' imply?
24. The process of using an image described in a vector-graphics format and converting it into a bitmapped image as output on a display or printer - or as storage in a bitmapped file is known as
25. In computer graphics - a technique in which irregularities in shading are created for simulating rough textures is called:
