In 3ds Max, which modifier smooths a low-poly mesh by subdividing faces and rounding edges?
Answer: TurboSmooth
TurboSmooth subdivides geometry and rounds corners, which gives a smoother surface.
Which polygon component in Maya is defined by exactly two vertices?
Answer: Edge
An edge is the line segment that connects two vertices.
A modeler needs a hollow cup from a solid cylinder. Which 3ds Max modifier adds thickness to a surface with an open top?
Answer: Shell
Shell adds inner or outer thickness to a surface, which makes it a solid object with walls.
What does the term 'n-gon' mean in polygon modeling?
Answer: A polygon with more than four sides
An n-gon is a face with five or more sides, and it can cause shading and subdivision artifacts.
In Maya, which tool cuts a new edge loop all the way around a mesh?
Answer: Insert Edge Loop
Insert Edge Loop adds a continuous loop of edges across connected quads.
Which type of geometry is defined by mathematical curves and gives smooth surfaces at any resolution?
Answer: NURBS
NURBS surfaces come from control curves, so they stay smooth at any tessellation level.
Why do animators usually prefer quad-based topology for characters?
Answer: Quads subdivide and deform predictably
Clean quad edge flow subdivides evenly and bends cleanly at joints.
