Abstract
A sketch of an object is entered into a computer graphics system which interfaces an operator to receive further criteria enabling the development of three-dimensional model of the sketched object. A box, defining perspective planes is established about the object after which various curves are entered, further defining surface positions of the object. The curves are classified and individually resolved to attain the three-dimensional model using transformations between screen space and model space. Once developed, the model enables a multitude of displays variously showing the object.
