Maya Maya 3D Modeling 2 — Questions and Answers
Question 1: In Maya, what is a 'NURBS' surface?
- A mathematically smooth surface defined by control points and curves (Correct answer)
- A polygon mesh with no triangles
- A subdivision surface with infinite resolution
- A texture-based displacement surface
Correct answer: A mathematically smooth surface defined by control points and curves
NURBS (Non-Uniform Rational B-Splines) are mathematically defined smooth surfaces controlled by CVs (control vertices) and knot vectors.
Question 2: What does the 'Combine' operation do to two separate polygon meshes in Maya?
- Merges them into a single mesh node without welding vertices (Correct answer)
- Welds all overlapping vertices between them
- Creates a boolean union of the two shapes
- Groups them under a single transform
Correct answer: Merges them into a single mesh node without welding vertices
Combine merges two polygon objects into a single mesh object node, but the vertices are not yet welded together.
Question 3: Which Maya tool allows you to cut new edges across polygon faces by clicking?
- Multi-Cut Tool (Correct answer)
- Split Polygon Tool
- Knife Tool
- Edge Loop Tool
Correct answer: Multi-Cut Tool
The Multi-Cut Tool (formerly Split Polygon Tool) lets you click across polygon faces to draw and insert new edges.
Question 4: What is the 'pivot point' of an object in Maya?
- The local origin point around which the object rotates and scales (Correct answer)
- The center of the bounding box of the object
- The point where the object attaches to a parent
- The first vertex created when modeling the object
Correct answer: The local origin point around which the object rotates and scales
The pivot point is the local origin of an object that determines the center of rotation and scaling operations.
Question 5: What does 'Delete History' do in Maya?
- Removes construction history nodes to clean up the scene (Correct answer)
- Undoes all recent operations on the object
- Deletes all keyframe animation data
- Removes the object from the outliner
Correct answer: Removes construction history nodes to clean up the scene
Delete History removes the construction history nodes (deformers, input nodes) associated with an object, reducing scene complexity.
Question 6: In Maya polygon modeling, what is an 'N-gon'?
- A polygon face with more than four sides (Correct answer)
- A face with exactly three sides
- A face with exactly four sides
- A face with no visible normals
Correct answer: A polygon face with more than four sides
An N-gon is any polygon face with five or more sides, which can cause issues with smoothing and subdivision.
