第三周

今天課程目標
1. 彩色方塊
2. 搭出簡單Robot

TODO: Dev C++ 裝 glut, 跑上週範例

TODO: google 找 NeHe
http://nehe.gamedev.net
找右邊 Lesson 05 (Dev C++ 版)

TODO: 程式碼排版注意事項

1. Dev C++ 的 Tool-Editor設定, 第3個Tab打開, 第4個SmartTab關掉

2. glBegin(..) 到 glEnd() 要加個縮排 (indent)

3. 有時候 會用 glColor3f(....); glVertex3f(...) 合成一行,方便閱讀理解

#include<GL\glut.h>

void display(){

glEnable(GL_DEPTH_TEST);

glRotatef(1, 1, 1, 0);

glClearColor(0, 0, 0, 1);

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glBegin(GL_TRIANGLES);

glColor3f(1.0f,0.0f,0.0f); glVertex3f( 0.0f, 1.0f, 0.0f);

glColor3f(0.0f,1.0f,0.0f); glVertex3f(-1.0f,-1.0f, 1.0f);

glColor3f(0.0f,0.0f,1.0f); glVertex3f( 1.0f,-1.0f, 1.0f);

glColor3f(1.0f,0.0f,0.0f); glVertex3f( 0.0f, 1.0f, 0.0f);

glColor3f(0.0f,0.0f,1.0f); glVertex3f( 1.0f,-1.0f, 1.0f);

glColor3f(0.0f,1.0f,0.0f); glVertex3f( 1.0f,-1.0f, -1.0f);

glColor3f(1.0f,0.0f,0.0f); glVertex3f( 0.0f, 1.0f, 0.0f);

glColor3f(0.0f,1.0f,0.0f); glVertex3f( 1.0f,-1.0f, -1.0f);

glColor3f(0.0f,0.0f,1.0f); glVertex3f(-1.0f,-1.0f, -1.0f);

glColor3f(1.0f,0.0f,0.0f); glVertex3f( 0.0f, 1.0f, 0.0f);

glColor3f(0.0f,0.0f,1.0f); glVertex3f(-1.0f,-1.0f,-1.0f);

glColor3f(0.0f,1.0f,0.0f); glVertex3f(-1.0f,-1.0f, 1.0f);

glEnd();

glutSwapBuffers();

glutPostRedisplay();

}

int main(){

glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

glutCreateWindow("Week03");

glutDisplayFunc(display);

glutMainLoop();

}
