%0 Journal Article %T The Location of Singular and Inflection Points for Planar Cubic B-Spline Curve %A Ye Zhenglin %A Wang Jiaye %J 计算机科学技术学报 %D 1992 %I %X Using vectors between control points(ai=Pi 1-Pi),parameters λ and μ(such that aj 1=λai μai 2)ae used to study the shape classification of planar parametric cubic B-spline curves.The regiosn of λμ space corresponding to different geometric features on the curves are investigated.These results are useful for curve design. %K 计算几何 %K 点 %K 定位 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=5B3AB970F71A803DEACDC0559115BFCF0A068CD97DD29835&cid=8240383F08CE46C8B05036380D75B607&jid=F57FEF5FAEE544283F43708D560ABF1B&aid=21002A2070560F515ECF75DCBBCF1CA0&yid=F53A2717BDB04D52&vid=DF92D298D3FF1E6E&iid=CA4FD0336C81A37A&sid=B31275AF3241DB2D&eid=708DD6B15D2464E8&journal_id=1000-9000&journal_name=计算机科学技术学报&referenced_num=1&reference_num=2
