What is a shell in polygon modeling? A disjointed set of connected polygons
What is the purpose of the Insert Edge Loop Tool? To add resolution selectively
Primitive-up modeling starts with basic shapes like cubes or spheres. True
Vertices, edges, and faces are the basic components of a polygon. True
Which tool helps correct non-planar faces? Multi-Cut
What is the recommended way to avoid non-planar faces? Use planar creation tools
Pressing key 3 in Maya displays rough geometry. False
Which tool helps correct non-planar faces? Multi-Cut
What does subdivision do? Adds polygonal resolution

Is a measure of the rate of directional change over a distance. Curvature
Subset of NURBS curves that are composed of two types of control vertices, anchors and tangents. Bezier Curve
One of the downsides of NURBS is that the surfaces themselves are made of four-sided patches. True
All NURBS objects are automatically converted to triangles at render time by the software. True
Is a measure of how smoothly two curves or surfaces flow into each other at their meeting point. Continuity
