CONSYS: A Collection of FORTRAN Subroutines to Produce Contour Maps of Data Surfaces Defined on Rectangular Grids.
Abstract
The CONSYS routines produce coordinate pairs for the straight-line vectors forming a contour map. The routines operate on user supplied samples of the x, y, and z coordinates that specify the data surface to be contoured. To reduce processing time, the routines assume that the data samples are available on a rectangular grid; surfaces represented by randomly scattered samples cannot be directly contoured by CONSYS. The routines are device--independent in the sense that at execution time the user must supply the names of subroutines that CONSYS can call to dispose of contour line coordinate pairs. CONSYS works entirely in the user's coordinate system, and the user is responsible for any scaling and translation necessary to map the coordinate pairs into a viewable area on the plotting device or graphics terminal being used.
