User's Guide for Subroutine PRNT3D. Physical Processes in Terrestrial and Aquatic Ecosystems, Computer Programs and Graphics Capabilities.
These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. PRNT3D is a subroutine package which generates a variety of printer plot displays. The displays include single and multiple x vs y functions, multi-value x, y relationships, and density plots which simulate three-dimensional effects by means of overprinting. The package features one- and two-dimensional interpolation, "zoom-in" capacities, automatic scaling, logarithmic scaling, flexible tilting, and multi-page plotting. This module assumes that PRNT3D is already incorporated as a subroutine in an existing program which uses the free-form input package and follows the conventions outlined in Design Standards for Computer Programs. A more thorough discussion of PRNT3D is contained in its programer's guide. (Author/CS)
