 week15

1-1 https://jsyeh.org/3dcg10/下載win32、data資料夾

 

將data資料夾拉進解壓縮過的windows資料夾內，打開Projection.exe

1-2 安裝GitBash，開啟專案 week15-1_gluLookAt

1-3 修改程式碼，讓專案也可移動視角

2-1 在範例中右鍵嘗試垂直投影glOrtho( )，透視投影glFrustum( )，glPersepective( )

2-2 開新專案 week15-2_Persepective

原本的glFrustum( )，透視，兩側較傾斜

glOrtho( )，變正了

gluPerspective( )

 static void resize(int width, int height){ ///step02-2 aspective ratio 長寬比    const float ar = (float) width / (float) height;    glViewport(0, 0, width, height);    glMatrixMode(GL_PROJECTION);///step02-2 切換成投影矩陣    glLoadIdentity();    ///glFrustum(-ar, ar, -1.0, 1.0, 2.0, 100.0);    glOrtho(-ar*3,ar*3,-1.0*3,1.0*3,2.0,100.0);///step02-2 *3看到全貌    gluPerspective(60,ar,0.01,1000);///step02-2
    glMatrixMode(GL_MODELVIEW);///step02-2 切換成model view矩陣    glLoadIdentity() ;///step02-2 設成單位矩陣}3 備份git status 紅色git add . 加進帳冊git status 綠色git config --global user.email git config --global user.namegit commit -mgit push4-1 開新專案week15-3_gluPerspective_gluLookAtvoid motion( )
