1. List the advantages of flat shading?
inexpensive to compute Appropriate for objects with flat surface Less pleasant for smooth surfaces.
2. What are the methods of shading?
Circulism Blended Circulism Dark Blacks Loose cross Hatching Tight cross Hatching Powder Shading
3. What is the UDC technique
UDC stands for User Defined Character set.It is graphics animation trick which used in early microcomputer system.
4. List the advantages of shadow mapping?
No knowledge or processing of the scene geometry is required. Only a single texture is required to hold shadowing information for each light. Avoids the high fill requirement of shadow volume.
5. What is computer graphics realism
The creation of realistic picture in computer graphics is known as realism.It is important in fields such as simulation,design,entertainments,advertising,research,education,command and control.
6. Define shadow volume.
The stencil buffer is used to find the interaction between the polygons in the scene and the shadow volume. This technique treat the shadows cast by objects as polygonal volumes.
7.What are the steps in rendering 3D texture.
Create the 3D texture Create Texture Coordinates Enable Texturing
8.What is the purpose of stencil buffer in shadowing?

8.What is the purpose of stencil buffer in shadowing?
The stencil buffer is used to compute which parts of the objects in the scene are in the shadow volume.It uses a non zero winding rule technique.For everypixel in the scene, the stencil value is incremented as it crosses a shadow boundary going into the shadow volume and decrement as it crosses a boundary going out.
9.What is texturing?
A texture image is a rectangular array of pixel data.Applying textures a graphical object to achieve a more interesting image or add information to the image without computing additional geometry.The key idea is to apply additional information to your image is computed and displayed.
10. What is shadow mapping?
Shadow mapping is just one of many different ways of producing shadows in your graphics applications each with its own advantages and disadvantages
