week 09

##week09-0_sample

0. 安裝 freeglut,將lib\libfreeglut.a複製成libglut32.a

1.File-New-Project,GLUT專案，week09-0_sample

##程式碼重新再利用

0.安裝git軟體

1.將GitHub上周的程式clone下來(先有程式碼)

 -在小黑Git Bash裡指令:

 -cd desktop

 -git clone https://github.com/.../2022cce

 -cd 2024graphicsb

 -start .

2.確定環境沒問題(OpenCV有沒有裝好?)

-安裝OpenCV 要勾Add PATH,裝在預設目錄

Setting Compiler裡,要把3個設定設好

-Compiler 加入C:\OpenCV2.1\include

-Linker加入C:\OpenCV2.1\lib

-Linker setting裡,加入3個 cv210 cxcore210 highgui210

重新開啟CodeBlocks

3.專案的設定是否需要修改(專案的右鍵,properties)

##開啟上週專案 week07-2_ojb_gundam_opencv_texture  

1.File-open,點選剛剛git下載的week07-2_ojb_gundam_opencv_texture

2.選week07-2_ojb_gundam_opencv_texture.cbp(codeblocks project檔)

3.Build & run 執行成功

##week09-1_gundam_texture_lighting_rotates

0.前一個目錄 week07-2_obj_gundam_opencv_texture整個複製到新的目錄week09-1_obj_gundam_opencv_texture_lighting

1.再用Notepad++開啟 目錄裡的.cbd檔,改內容

2.把打光的8行陣列,貼在int main()之前

3.把打光的12+2行函式,貼到glutMainLoop()之前

4.glmDraw(pmodel,GLM_SMOOTH|GLM_TEXTURE)要刪掉中間的GLM_MATERIAL

為了讓畫面好看一點,打光漂亮,模型旋轉,我們做幾個修改

1.改變光的位置(改陣列的值

...

const GLfloat light_position[] = { 2.0f, 5.0f, 5.0f, 0.0f };

變成

const GLfloat light_position[] = { 2.0f, 5.0f, -5.0f, 0.0f };

...

2.在display() 加入旋轉

...

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(angle++,0,1,0);

        drawmodel(); ///glutSolidTeapot( 0.3 );

    glPopMatrix();

    glutSwapBuffers();

}

...

int main(...)

{...

glutIdleFunc(display);

}

##week09-2_glutSolidCube_glutSolidTeapot_glutSolidSphere

1.File-New-Project,GLUT專案，week09-2_glutSolidCube_glutSolidTeapot_glutSolidSphere

2.貼入11行GLUT程式

3.加入glutSolidTeapot(0.3);///茶壺    glutSolidCube(0.3);///方塊     glutSolidSphere(0.3,30,30);///圓球

4.配合glPushMatrix()   glTranslatef()   glPopMatrix()  來移動

##week09-3_glutWireCube_glutWireTeapot_glutWire_Sphere

1.File-New-Project,GLUT專案，week09-3_glutWireCube_glutWireTeapot_glutWire_Sphere

2.直接貼上09-2程式碼

3.剛display()裡有三段實心程式碼

##上傳github注意事項

1.小黑關掉

2.codeblocks關掉(都要按YES存檔)

3.把每個專案的兩個目錄(BIN  OBJ)刪掉

4.把 .depend  .layout 刪掉

5.把今天的4個程式的專案目錄,上傳到github
