(57) [summary] I determined by computer graphics [challenge] the exact curved surface. Using [SOLUTION] computer, a method for determining the position characteristics of the computer surface model on position is described by a set of parameters, one set has a set of subdivision rules surface model corresponding It is written in the control vertices of the control vertices can be parameterized set of control vertices are regular, the steps of: accepting an input value that specifies the coordinates describing the control vertices surface model, is subdivided coordinates of the control vertices are given and generating a projection control vertices projected onto eigenspace derived from a matrix representation of the rule, the step of determining which set of nested hierarchically tile regular the surface model is or contains the position and, I and calculating as a function of the control vertices and projected nested tile, the order of one of the control vertices, the determined its position. Calculated positions are stored in the computer memory.
