Functions and Procedures

procedure PLOTS; stdcall;
procedure SYMBOL(var XD: Real; var YD: Real; var Scale: Real; var Dummy1: longint; var Dummy2: Real; var Dummy3: longint); stdcall;
procedure PLOT(var X, Y: Real; var IPEN: integer); stdcall;
procedure NUMBER (var X0,Y0,Scale: Real; var NumberToPlot: Real; var Dummy2: Real; var Dummy3: longint); stdcall;
procedure SpecifyContourLevel(const ContourLevel: Real; const TriangleNumber, TriangleSide: longint);
procedure StoreArrays(X, Y: TRealArray; Triangles: TIntArray);

Types

TShowPlot = procedure;

Variables

ShowPlot: TShowPlot = nil;
ShowPlotObject: TShowPlotObject = nil;

Description

Functions and Procedures

procedure PLOTS; stdcall;

INITIALIZE PLOTTING

procedure SYMBOL(var XD: Real; var YD: Real; var Scale: Real; var Dummy1: longint; var Dummy2: Real; var Dummy3: longint); stdcall;

As used here, simply plot a dot at the specified location.

procedure PLOT(var X, Y: Real; var IPEN: integer); stdcall;

calling with IPEN = 3 starts a new line. calling with IPEN = 2 continues a line. calling with IPEN = 999 closes the plot by setting CurrentLineList to nil and then calls ShowPlot or ShowPlotObject if either has been assigned.

procedure NUMBER (var X0,Y0,Scale: Real; var NumberToPlot: Real; var Dummy2: Real; var Dummy3: longint); stdcall;

NUMBER adds X0, Y0 and NumberToPlot to CurrentLineList.Numbers.

procedure SpecifyContourLevel(const ContourLevel: Real; const TriangleNumber, TriangleSide: longint);

SpecifyContourLevel sets CurrentLine.ContourLevel and CurrentLine.TriangleNumber of CurrentLine.

procedure StoreArrays(X, Y: TRealArray; Triangles: TIntArray);

StoreArrays sets CurrentLineList.XD, CurrentLineList.YD, and CurrentLineList.Triangles of CurrentLineList.

Types

TShowPlot = procedure;

TShowPlot is a type of procedure used to display a contour plot.

Variables

ShowPlot: TShowPlot = nil;

If assigned, ShowPlot is called in PLOT when all the contour lines have been created. Either ShowPlot of ShowPlotObject Should be assigned before calling TRICP_Pascal.

ShowPlotObject: TShowPlotObject = nil;

If assigned, ShowPlotObject is called in PLOT when all the contour lines have been created. Either ShowPlotObject of ShowPlot Should be assigned before calling TRICP_Pascal.
