In the B-spline curve, which knot vector classification has the same shape (when plotting on the graph) for each blending function?
a) Uniform
b) Open uniform
c) Non uniform
d) Classic uniform
Which of these is a correct equation
for finding parametric first-order derivatives at the first endpoint in bezier
curves?
a) 𝓅ˊ(0) = −𝓃𝓅0 + 𝓃𝓅1
b) 𝓅ˊ(0) = −𝓃𝓅1 + 𝓃𝓅2
c) 𝓅ˊ(0) = −𝓃𝓅n-1 + 𝓃𝓅n
d) 𝓅ˊ(0) = −𝓃𝓅n + 𝓃𝓅n+1
