   3 dni temu · Initially, as depicted in Fig. 6a, the boundary curves are parameterized using an approximate chord-length method tailored to their individual representations. However, this method faces challenges in creating analysis-suitable parameterizations, mainly due to a mismatch in parameter speeds that degrades the parameterization quality.

   4 dni temu · Vector triple product involves three vectors. When you take the cross product of the vectors B and C, and then take the cross product of the result with vector A, it gives a vector perpendicular to both B and C, with its magnitude dependent on A and the angle between B and C.
