What is the term for a setting that can vary to influence an object's geometry?

• A. Parameter
• B. Attribute
• C. Keyframe
• D. Texture

Answer: (A)

A parameter is the adjustable setting that directly controls an object's geometry. When you change a parameter, you alter dimensions or form—like radius, height, or subdivision counts—so the model's shape updates accordingly. You can also animate a parameter by keyframing, making the geometry evolve over time as the value changes. This makes parameters distinct from attributes (which are non-geometric properties such as color or visibility), keyframes (which are time-stamped snapshots used for animation rather than the control itself), and textures (images mapped to surfaces for appearance rather than shaping geometry).
