1. Surface shading is a combination of the basic an object and any textures that are

colour

shader

material

2. In visual arts, a is any kind of surface detail both visual and tactile.

shader

texture

material


3. A is a collection of connected rendering nodes that defines how colours and textures contribute.

shading network

texturing network

mapping network


4. materials represent the types of surfaces onto which you can map textures.

Surface

Displacement

Volumetric


5. You can create when you want to use more than one material for an object.

layered textures

layered materials

layered shaders


6. textures wrap around an object, like gift wrapping.

2D

3D

2.5D


7. Procedural textures are 2D or 3D plots of mathematical functions that have limitations in resolution.

True

False

8. File textures filter is better than most textures and can result in better image quality.

2D

3D

procedural

9. technique projects the texture through 3D space like a slide projector.

Normal mapping

Projection mapping

Stencil mapping


10. are greyscale textures you map to objects to create the illusion of surface relief.

Bump maps

Displacement maps

Normal maps


11. The appearance of specular highlights of a/an material depends on the properties of these grooves and their orientation.

Phong E

Blinn

Anisotropic

12. Shiny objects reflect light directly; matte objects light.

deflect

absorb

diffuse

13. If the Transparency Value is the surface is totally

transparent

opaque

invisible

14. UVs are dimensional texture coordinates that reside with the vertex component information for polygonal and subdivision surface meshes.

three

two

uni

15. creates UVs for a polygon mesh by attempting to find the best UV placement by simultaneously projecting from multiple planes.

Planar mapping

Automatic mapping

Camera mapping

Answer the following questions in brief. Each question carries 5 marks.

16. Differentiate between Blinn and Anisotropic shaders. Give two different real world examples for each shader.

17. Define any two of the following passes. How can they be used in a composition?

Beauty Pass

Shadow Pass

Ambient Occlusion Pass

18. Write down the process of unwrapping a torso in the brief. Mention every step from creating the UV layout to exporting the UV layout.
