摘要
本文构造了一种新的变换——变比投影变换,记为VRP(variable ratioand projective transformation)。研究了它的性质及在数控加工图形校验中的应用。
A new transformation is constructed.It is called a variable ratio and protective transformation.It is abridged VRP-transformation and is denoted VRP.Its properties are discussed and its application in CAM graphic display are introduced.
