電腦圖學 Week09 🥴

範例檔：week09-0_sample

1. moodle下載 freeglut 拖到桌面

2. 把桌面\freglut\lib\libfreeglut.a 複製成 libglut32.a

3. CodeBlocks開GLUT專案, 目錄選桌面, 專案名取week09-0_sample

4. GLUT要選桌面的 freeglut

複習檔案

1. 安裝git, 把github上之前寫過的程式複製到桌面

- cd desktop

- git clone https://github.com/xiyu-emma/2024graphicsa

2. 安裝 OpenCV 2.1

- 安裝第三步驟, Add OpenCV to system PATH(勾第2或3個, 不要勾第1個)

- 目錄不要改,要用預設的

- 要重開CodeBlocks

3. CodeBlocks 的 settings>compiler 加入 opencv 的3個設定

- Search directories > Compiler 要加上 C:\OpenCV2.1\include

- Search directories > Linker 要加上 C:\OpenCV2.1\lib

- Linker settings 要加上 cv210 / cxcore210 / highgui210

4. 開啟上週的檔案week08-3_glm_gundam_opencv_texture_lighting(.cbp檔)

鋼彈貼圖：week09-1_glm_gundam_opencv_texture

1. 關掉week08-3, 右鍵close project

2. 把整個week08-3複製貼上到桌面, 檔名改成week09-1

3. cbp檔右鍵用notepad++開啟, 把所有week08-3都改成week09-1

4. CodeBlocks開啟week09-1, 把視窗名稱改成glutCreateWindow("week09 Gundam");

三個實心形狀：

week09-2_glutSolidTeapot_glutSolidCube_glutSolidSphere

1. CodeBlocks開GLUT專案, 目錄選桌面, 專案名取
week09-2_glutSolidTeapot_glutSolidCube_glutSolidSphere

2. GLUT要選桌面的 freeglut

3. 貼上glut 11行程式碼

4. 把glutSolidTeapot(0.3);改成glutSolidCube(0.3); 就會變成方塊

5. 把glutSolidTeapot(0.3);改成glutSolidSphere(0.3, 30, 30); 就會變成圓形

6. 加上程式碼讓三個形狀同時出現, 並移動位置

glPushMatrix();

  glTranslatef(-0.5, +0.3, 0);

  glutSolidTeapot(0.3);

glPopMatrix();

glPushMatrix();

  glTranslatef(+0.0, +0.3, 0);

  glutSolidCube(0.3);

glPopMatrix();

glPushMatrix();

  glTranslatef(+0.5, +0.3, 0);

  glutSolidSphere(0.3, 30, 30);

glPopMatrix();

三個空心形狀：
week09-3_glutWireTeapot_glutWireCube_glutWireSphere

1. CodeBlocks開GLUT專案, 目錄選桌面, 專案名取
week09-3_glutWireTeapot_glutWireCube_glutWireSphere

2. GLUT要選桌面的 freeglut

3. 貼上glut 11行程式碼

4. 把形狀的部分再複製一次, Solid都改成Wired, 座標改成負的
glPushMatrix();
  glTranslatef(-0.5, -0.3, 0);
  glutWireTeapot(0.3);
glPopMatrix();
glPushMatrix();
  glTranslatef(+0.0, -0.3, 0);
  glutWireCube(0.3);
glPopMatrix();
glPushMatrix();
  glTranslatef(+0.5, -0.3, 0);
  glutWireSphere(0.3, 30, 30);
glPopMatrix();
glutSwapBuffers();
