<p>A system includes plural processors and an interactive display library for interactively displaying a model having a complex surface. The library includes a surface pre-processor for pre-processing the model to provide a plurality of surface primitives; an application program for displaying the model with respect to a first eye-point of a plurality of eye-points and for selecting a second eye-point of the eye-points for display of the model with respect to the second eye-point; and a visibility thread for performing a visibility computation (92). The library further includes a tessellation thread (96) which tessellates each selected surface primitive to provide a plurality of triangles or triangle-strips representative of the selected surface primitive with respect to the second eye-point; and a triangle rendering thread which employs a graphics board to render the triangles or triangle-strips and, thus, display the model with respect to the second eye-point.</p> |
