Question 1.
What defines a Hermite curve?
Show hintHide hint
Think about what controls the direction of a curve.
Question 2.
Name one application of Bézier curves.
Show hintHide hint
Consider where smoothness and design are important.
3Question 3.
What is the primary advantage of using Hermite curves?
- They are easy to calculate
- They provide controlled transitions.
- They can only represent straight lines.
Show hintHide hint
Consider what aspect of Hermite curves allows unique shapes.
4Question 4.
Bézier curves always remain within:
- True
- False
Show hintHide hint
Think about what control points are doing for the shape.
Question 5.
Given control points for a Bézier curve, derive the equation for a cubic Bézier curve defined by points (0, 0), (1, 2), (3, 3), (4, 1).
Show hintHide hint
Use the properties of combinations and polynomial expansion.
Question 6.
Illustrate the impact of modifying a single control point on a B-spline curve, showing the before-and-after shapes.
Show hintHide hint
Focus on how local adjustments manifest into changes in the curve.
