| Abstract: | Singular inflection point distributing of B zier curve is studied in this paper. The full and need condition to make singular inflection point exist is given . The full and need condition to differentiate singular inflection point distributing of B zier curve is predigested, and the B zier curve based on barycenter coordination form is listed. |
| Keywords: | Bezier curve inflection point singular point |
