Question 1.
What is a B-spline curve?
Show hintHide hint
Look for the definition involving control points.
Question 2.
How does modifying a control point affect a B-spline curve?
Show hintHide hint
Think about local control.
3Question 3.
What is a key feature of B-spline curves?
- They pass through all control points
- They allow local shape control
- They are always linear
Show hintHide hint
Think about what differentiates them from other curves.
4Question 4.
True or False: B-spline curves always pass through their control points.
- True
- False
Show hintHide hint
Consider the concept of control points and curve design.
Question 5.
You are tasked with designing a car's side profile using B-spline curves. Choose your control points and degree; describe how you would refine the shape while ensuring smooth transitions.
Show hintHide hint
Think about how curvature interacts with control points.
Question 6.
Given specific values for a knot vector, explain how this impacts the shape of the B-spline curve derived from it. Provide an example.
Show hintHide hint
Analyze how the spacing of knots alters control.
