1. Some of the most basic attributes of materials include colour, transparency and

shine

texture

translucency

2. In Maya, you create surface detail with textures connected to the material of objects as

surface maps

colour maps

texture maps

3. Shading networks are designed as a data flow network, where data streams from the side of the network towards a final shaded result that emerges from the right node.

4. The material lets you use an image to specify surface relief on objects in your scene.

surface

displacement

volumetric

5. The Layered Shader has an attribute called that causes the shader type to layer materials or layer textures.

compositing flag

layering flag

blending flag

6. textures project through objects, like veins in the marble or wood.

2.5D

3D

7. 3D procedural textures ignore UV coordinates.

True

False

8. File textures are scanned from photographs taken with a digital camera.

bitmaps

movies

files

9. technique lets you use either a mask file or a colour key to remove a part of the texture.

Normal mapping

Projection mapping

Stencil mapping

10. are greyscale textures you map to objects to create true surface relief.

Bump maps

Displacement maps

Normal maps

11. The soft highlights on Blinn surfaces are less likely to exhibit roping or flickering for thin highlights than the harder highlights on surfaces.

Phong

PhongE

Anisotropic

12. Specular highlights depend directly on the not the position of the light

view

angle

intensity

13. is the colour and brightness of light that a material appears to be emitting.

Ambient colour

Self-illumination

Incandescence

14. UVs act as marker points that control which points on the textures map correspond to which the mesh.

vertices

polygons

edges

15. Planar mapping typically gives UV shells.

overlapping

normalized

(c)flatten

16. What is the difference between Bump Map and Normal Map? Give an example for both.

17. Explain the following utilities available in Maya (any
