    A description is given of the TIPS electronic table, a common user's model that enables the end user to imagine and anticipate the actions of the system and thus develop it into a professional instrument. The objective of the electronic table design has been to simulate the use of an ordinary worktable/lightbox. The application support packages and system hardware are described, and the application of the table in prepress graphics work, image enhancement work, and page makeup is discussed.

  • A Method for Solving the Visibility Problem

    Page(s): 26 - 33
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (7321 KB)  

    This method for describing the visibility problem is based on the concept of analyzing the problem utilizing connectivity information. The result is a uniform description of visibility algorithms in terms of two basic functions, the test of projective equivalence and the comparison of the distance from the observer, and the use of connectivity information. This result leads to a hierarchy of visibility algorithms, which allows the characterization of the typical advantages and disadvantages of certain strategies independently of the quality of the implementation. The calculation rate of the new algorithm is substantially better than that of existing methods. Study of the distributivity of the visibility problem also shows that the use of connectivity information leads to an algorithmic improvement as well as a better usage of distributed systems.

  • Shaded Display of Digital Maps

    The display of shaded pictures of terrain can take advantage of the geometric properties of the data. In particular, the authors discuss the bilinear interpolation of a surface given by its values of a rectangular grid and extend front and back facing notions to patches. Then they study the clipping problem in this particular context and discuss two hidden surface elimination techniques, priority list and ray tracing. View full abstract»

  • Using Interactive Graphics for Fitting Surfaces to Scattered Data

    Robust software for reconstructing a surface from scattered data has been implemented in an interactive system with graphical facilities and with highly modular machine-independent structure. Particular attention is paid to the mathematical capabilities of the system, which consist of a wide range of numerical methods for constructing a smooth bivariate function F(x, y) that approximates or interpolates certain prescribed values fk at the points (xk, yk), 1, . . ., N. These points must be distinct and noncolinear. Since this is a typical laboratory computer problem, the system has been designed for a minicomputer, and the need for both machine and operating system independence has been taken into account.

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (3669 KB)  

    Interactive programming using clever look-up tables can cause applications problems. A simple recursive algorithm is described that avoids difficulties by dividing a multiplane frame buffer into logical layers. This separation and restructuring process can be envisioned as a computer graphics analogy to the display of multiple transparencies with an overhead projector. View full abstract»
