#include <GL/glut.h>

void display()

{

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char**argv){

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week03");

    glutDisplayFunc(display);

    glutMainLoop();

}

將solid改成wire能變空心茶壺

先複習上週,用上週的方法開啟glut

之後把程式碼全部刪掉

按照老師範例打程式碼就能出現茶壺

輸入glColor3f(0.5,1.0,0.5);或glColor3ub(255,0,255); 可以改變茶壺顏色

glBegin(GL_POLYGON);

        glColor3f(1,0,0);glVertex2f(1,0);

        glColor3f(0,1,0);glVertex2f(-1,1);

        glColor3f(0,0,1);glVertex2f(-1,-1);
造出三角形顏色(左)和頂點(右)

 glEnd();

   glutSwapBuffers()

改line,polygon,points
