WebUsing a similar method to the parabolic blending of Overhauser [16], we generate a quaternion curve Q i (t) which interpolates the two orientations q i and q i+1 while smoothly blending the two circular quaternion curves C i (t) and C i+1 (t) with a blending function f(t) of degree (2k \Gamma 1). The quaternion curve Q i has the same ... WebParabolic blending allows you to shape curves directly, without trying to come up with an equation to do the job. Figure 2 is a cursive R which I was able to draw in only a few minutes. Only ten control points were required, and I am sure it could be done with fewer. The control points generating the R are shown in Figure 3, numbered in the ...
