Abstract
A display apparatus and a modelling method for computer graphics includes a first memory for storing a first three-dimensional model, a detailed model, of a body represented by at least one of desired first number of dimensions, a desired first number of parameters and desired first parametric quantities, an arithmetic unit for arithmetically determining a second three-dimensional model, a simplified model, by varying at least one of the first number of dimensions, the first number of parameters and the first parametric quantities to at least one of a second number of dimensions, a second number of parameters and second parametric quantities in accordance with an algorithm for thereby creating automatically a simplified model for a body of less importance. A second memory stores the simplified model. A selector selects the first three-dimensional model or the second three-dimensional model by reference to a preset index for evaluation. A display unit displays the first three-dimensional model or the second three-dimensional model as selected.
