混沌ICON圖標(biāo)繪制

實(shí)驗(yàn)三一上機(jī)題目:實(shí)現(xiàn)ICON圖標(biāo)繪制二上機(jī)目的與要求理解平面與屏幕的對(duì)應(yīng)關(guān)系，掌握吸引子的構(gòu)造原理與色帶(colorband)的制作方法。熟悉ICON圖標(biāo)的兩個(gè)計(jì)算公式，能夠用計(jì)算機(jī)生成多幅且有不同對(duì)稱形式的ICON圖標(biāo)檔案。三思路及步驟生成圖標(biāo)對(duì)稱最基本的公式如下：F(z)=[入+azz+BRe(zn)+3i]z+Yzn-1其中入a0s是實(shí)參，當(dāng)s二0時(shí)該公式具有Dn對(duì)稱，當(dāng)w#0時(shí)，該公式具有Zn對(duì)稱。利用編程語言實(shí)現(xiàn)平面上的點(diǎn)與屏幕像素坐標(biāo)的對(duì)應(yīng)函數(shù)，自定義調(diào)色板和色帶分配的函數(shù)，編程實(shí)現(xiàn)點(diǎn)擊次數(shù)累加器函數(shù)。運(yùn)用計(jì)算機(jī)語言寫出ICON圖標(biāo)的計(jì)算公式，形成迭代函數(shù)，寫出主函數(shù)，實(shí)行聯(lián)調(diào)。利用AppendixA中的參數(shù)表中的參數(shù)，生成多幅ICON吸引子圖形，進(jìn)行簡(jiǎn)單調(diào)色，存圖。在VC6.0中新建一個(gè)工程ICON，建立對(duì)話框。再打開菜單，選Project——AddProject，新建一個(gè)C頭文件，起名為Variable.h。在Variable.h文件里定義調(diào)色板，需要迭代到的顏色定義在COLORREFcolorlist[]結(jié)構(gòu)體里。以函數(shù)fxynew()，利用生成圖標(biāo)對(duì)稱的基本公式，計(jì)算迭代后新的x與y的值，分別賦給xnew和ynew，之后計(jì)算x點(diǎn)y點(diǎn)對(duì)應(yīng)的坐標(biāo)，并計(jì)算點(diǎn)擊次數(shù)，擊中一次加1，再根據(jù)點(diǎn)擊次數(shù)著色。在ICONDlg.cpp里引用此頭文件。在ICON的對(duì)話框窗體里添加按鈕“繪制吸引子”，“保存”，“退出”，編輯框“顯示比例”，參數(shù)a，8,y，s，入，以及“迭代次數(shù)”，“對(duì)稱維數(shù)”。為編輯框添加相應(yīng)的成員變量，實(shí)現(xiàn)通過調(diào)整參數(shù)，可以繪制出不同對(duì)稱圖形，并能調(diào)整輸出比例的功能。a，8，y，s，入等變量的初始值如下圖(Emperor'sCloak)：CIconDlg::CIconDlg(CWnd*pParent/*=NULL*/):CDialog(CIconDlg::IDD,pParent){//{<AFX_DATA_INIT(CIconDlg)n_a=1.806;n_b=0.0;nr=1.0;=0.0;n_y=-1.806;nscale=1.5;n_n=1500000;n_sd=5;//}}AFX_DfiTfi_INIT//NotethatLoadicondoesnotrequireasubsequentDestroyIconinWin32mhlcon=AfxGetApp()->LoadIcon(IDRJIfiINFRAME);點(diǎn)擊“繪制吸引子”，在對(duì)話框里繪制一個(gè)767*767的白色繪圖區(qū)域，起始繪制點(diǎn)為(-0.234,-0.12345)。以函數(shù)fxynew(x1,y1,m_a,m_b,m_r,m_w,m_y,m_sd)獲取輸入的參數(shù)，生成的圖形控制在(0,0)，(768,768)區(qū)域中，每迭代一次，在當(dāng)前x,y坐標(biāo)添加一次colorlist里的顏色。迭代完成后，輸出“繪圖完畢，可以將圖片保存”字樣。保存圖片：可將白色區(qū)域里的圖片保存為768*768的bmp圖片。相關(guān)代碼：ICONDlg.cpp:CIconDlg::CIconDlg(CWnd*pParent/*=NULL*/):CDialog(CIconDlg::IDD,pParent)(//{{AFX_DATA_INIT(CIconDlg)/*m_a=5.0;m_b=1.5;m_r=1.0;m_w=0.0;m_y=-2.7;*//*m_a=1.0;m_b=-0.1;m_r=0.167;m_w=0.0;m_y=-2.08;*//*m_a=-1.0;m_b=0.1;m_r=-0.82;m_w=0.12;m_y=1.56;*//*m_a=1.806;m_b=0.0;m_r=1.0;m_w=0.0;m_y=-1.806;*//*m_a=2.0;m_b=0.0;m_r=1.0;m_w=0.1;m_y=-1.86;*//*m_a=-1.0;m_b=0.1;m_r=-0.82;m_w=0.12;m_y=1.56;*/m_a=-1.0;m_b=0.1;m_r=-0.805;m_w=0.0;m_y=1.5;m_scale=1.0;m_n=1500000;m_sd=3;//}}AFX_DATA_INIT//NotethatLoadIcondoesnotrequireasubsequentDestroyIconinWin32m_hIcon=AfxGetApp()->LoadIcon(IDR_MAINFRAME);}voidCIconDlg::DoDataExchange(CDataExchange*pDX)(CDialog::DoDataExchange(pDX);//{{AFX_DATA_MAP(CIconDlg)DDX_Text(pDX,IDC_a,m_a);DDX_Text(pDX,IDC_b,m_b);DDX_Text(pDX,IDC_n,m_n);DDX_Text(pDX,IDC_r,m_r);DDX_Text(pDX,IDC_sd,m_sd);DDX_Text(pDX,IDC_w,m_w);DDX_Text(pDX,IDC_y,m_y);DDX_Text(pDX,IDC_EDIT1,m_scale);//}}AFX_DATA_MAP}BEGIN_MESSAGE_MAP(CIconDlg,CDialog)//{{AFX_MSG_MAP(CIconDlg)ON_WM_SYSCOMMAND()ON_WM_PAINT()ON_WM_QUERYDRAGICON()ON_BN_CLICKED(ID_OnButtonCreate,OnOnButtonCreate)ON_BN_CLICKED(ID_OnButtonCreate2,OnSave)//}}AFX_MSG_MAPEND_MESSAGE_MAP()///////////////////////////////////////////////////////////////////////////////CIconDlgmessagehandlersBOOLCIconDlg::OnInitDialog(){CDialog::OnInitDialog();MoveWindow(0,0,1024,768,true);//Add"About..."menuitemtosystemmenu.//IDM_ABOUTBOXmustbeinthesystemcommandrange.ASSERT((IDM_ABOUTBOX&0xFFF0)==IDM_ABOUTBOX);ASSERT(IDM_ABOUTBOX<0xF000);CMenu*pSysMenu=GetSystemMenu(FALSE);if(pSysMenu!=NULL){CStringstrAboutMenu;strAboutMenu.LoadString(IDS_ABOUTBOX);if(!strAboutMenu.IsEmpty()){pSysMenu->AppendMenu(MF_SEPARATOR);pSysMenu->AppendMenu(MF_STRING,IDM_ABOUTBOX,strAboutMenu);}}//SettheiconforthisdThloframeworkdoesthisautomatically//whentheapplication'smainwindowisnotadialogSetIcon(m_hIcon,TRUE); //SetbigiconSetIcon(m_hIcon,FALSE);//Setsmalliconthis->MoveWindow(0,0,1024,768,true)//將窗口設(shè)成1024*768大小//TODO:AddextrainitializationherereturnTRUE;//returnTRUEunlessyousetthefocustoacontrol}voidCIconDlg::OnSysCommand(UINTnID,LPARAMlParam){if((nID&0xFFF0)==IDM_ABOUTBOX){CAboutDlgdlgAbout;dlgAbout.DoModal();}else{CDialog::OnSysCommand(nID,lParam);}
