1. What is the purpose of the mesh select modifier?
• The mesh select modifier allows you to create a sub-object selection so that you can modify a portion of an object independently without modifying the entire object.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
2. Which type of material is used with the material modifier?
• multi/sub-object
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
3. What is a displacement approximation modifier used for?
• A displacement approximation modifier is used in conjunction with displacement mapping to deform the surface geometry of a “non-mesh” object.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
4. How does applying an edit patch modifier to a parametric object differ from converting the object into an editable patch object?
• An object with an edit patch modifier is not actually converted to an editable patch, allowing the base object to remain parametric.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
5. When is the normalized spline modifier used?
• The normalize spline modifier is used to space vertices equally along the length of a spline, allowing the line to be used as a motion path to generate a constant velocity.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
6. The surface modifier generates a patch grid from what type of object?
• splines
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
7. Why would you use the delete mesh modifier instead of deleting items at the sub-object level?
• Using the modifier keeps the base object parametric.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
8. What function does the tessellate modifier perform?
• It subdivides faces on an object, which allows you to add smoothness for rendering.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
9. What effect can be created with the displace modifier?
• A moving force field effect can be created by applying the displace modifier and animating the gizmo, or using an animation as the bitmap.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
10. The lattice modifier produces what type of object?
• wireframe
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
11. What does the push modifier do?
• The push modifier allows you to scale an object up or down along the normals of its faces.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
12. What do the xform and linked xform modifiers allow you to do?
• The xform and linked xform modifiers allow you to apply a transform to a selection of sub-objects and place it in the modifier stack.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
13. How does the xform modifier differ from the linked xform modifier?
• When using the linked xform modifier, the transform is controlled by the transform of a control object.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
14. What does FFD stand for?
• Free Form Deformation
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
15. Which FFD modifiers allow you to set the number of control points?
• FFD box
• FFD cylinder
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
16. If a melt modifier has a high solidity value, what effect is produced on the object?
• The object melts more on the outside than the inside.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
17. What does the flex modifier do?
• It causes a portion of the object to “lag” as the object is moved in an animation.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
18. With what is the skin modifier designed to be used?
• bones systems
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
19. What is the main difference between world space modifiers and object space modifiers?
• The effects of a world space modifier are based on world space rather than object space.
• The effects change as the object is moved around in the scene, even if the object’s parameters remain unchanged.
• The effects of an object space modifier are dependent on object space only.
• The effects of an object space modifier do not change simply by moving the object around in the scene.
From: CHAPTER 8– Modeling with Modifiers3DS MAX AND ITS APPLICATIONS
20. What is the purpose of the point cache modifier?
• The point cache modifier records animation information as changes in vertex location. The vertex information is saved to a file and can be retrieved for animation playback.
