CAP 201a - Computer Animation I
Review for Final Exam (This test will not be cumulative.)
The following questions are provided to help you study for the last test. Do not expect to see these exact questions on the test.
- What are three methods of opening the Material Editor?
- What must you do to render one frame to the screen if you have already rendered a movie of the current scene?
- What is a specular highlight?
What property of a specular highlight controls its brightness?
What property of a specular highlight controls its size?
- What do gray triangles in the corners of a material sample slot mean?
What does it mean if the triangles are white?
- Assume you have assigned a bitmap to the diffuse color map property of a sample. How can you assign it to the currently selected object in your scene?
- Assume you have assigned the material to the object in the scene, but you still cannot see it in the viewport. What should you click to make it visible?
- Assume you have assigned the wrong bitmap to a map channel. What can you do to remove the map from that channel, without replacing it with another one? There are two answers.
- Troubleshooting: assume you are trying to use a map in a scene that someone else has worked on. You open the material editor, and see the map you want to use in two sample slots. The first one shows the map material on a sphere in the sample slot. The second one shows the map material on a rectangle, filling the sample slot. Only one of these will work. Which one?
- How do you adjust a texture map to make it look bumpy?
- What is the effect of decreasing the Glossiness of a material?
- What is an MSO material? How can you create one?
- What is UVW mapping?
- Why is planar mapping suited to mapping a flag, but box mapping is not? Which would have been better for the Red Rocket side view reference plane?

- What would you use to combine several separate renders of a scene?
- What is the Clone Rendered Frame Window button for? What does it allow you to do that you can't do without it?
