Drawing for example study of flashcc

​​FlasCC Example study Drawing​​

This example is mainly to show you voronoi Drawing method of graph .

Voronoi chart , Also called ​ ​ Tyson polygon ​​​ or ​ ​Dirichlet​​​ chart , Please refer to here for details ​ ​http://baike.baidu.com/view/501103.htm​​, This is not the point of this example .

This example doesn't show you much ,AS3 Related calls and C API Use , And there is not much difference between them . only One difference is , In this case voronoi Graph generation , Used C++ class. in other words , This example , Let's see FlasCC Yes C++ Support for .

The following code , Is the example native code , There is no comment in the middle . This is because , There is no need for comments . Used , It's all in the front Interop Has been described in .

#include <stdio.h>

#include <time.h>

#include <stdlib.h>

#include "VoronoiDiagramGenerator.h"

#include "AS3/AS3.h"

int main(int argc,char **argv)

{

    int stagewidth, stageheight;

    inline_as3(

        "import flash.display.Stage;\n"

        "import flash.display.Graphics;\n"

        "import com.adobe.flascc.CModule;\n"

        "var gfx = CModule.rootSprite.graphics;\n"

        "gfx.lineStyle(1, 0);\n"

        "gfx.beginFill(0, 0.0);\n"

        "%0 = CModule.rootSprite.stage.stageWidth;\n"

        "%1 = CModule.rootSprite.stage.stageHeight;\n"

        : "=r"(stagewidth),"=r"(stageheight) :

    );

    const int cellcount = 512;

    float xvals[cellcount], yvals[cellcount];

    for(int i=0; i<cellcount; i++) {

        xvals[i] = stagewidth * ((float)rand()/(float)RAND_MAX);

        yvals[i] = stageheight * ((float)rand()/(float)RAND_MAX);

    }

    VoronoiDiagramGenerator vdg;

    vdg.generateVoronoi(xvals, yvals, cellcount, 0, stagewidth, 0, stageheight, 3);

    vdg.resetIterator();

    float x1,y1,x2,y2;

    while(vdg.getNext(x1,y1,x2,y2))

    {

        inline_as3("gfx.moveTo(%0,%1);\n" : : "r"(x1), "r"(y1));

        inline_as3("gfx.lineTo(%0,%1);\n" : : "r"(x2), "r"(y2));

    }

    inline_as3("gfx.endFill();\n");

}
