week10

1.www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10裡面先下載data,win32,glut32.dll

2.將windows解壓縮

3.將data解壓縮至windows的資料夾,並將glut32.dll移進去

4.按滑鼠右鍵點選swap translate/rotate

 5.https://www.transmissionzero.co.uk/software/freeglut-devel/

中下載Download freeglut 3.0.0 for MinGW

 6.freeglut解壓縮到桌面,點進lib資料夾將libfreeglut.a複製並改名為libglut32.a

 7.新增一個project選擇glut project

 8.複製程式碼並執行

#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("Week10 TRT");

    glutDisplayFunc(display);

    glutMainLoop();

}

9.新增一個圓錐體,做茶壺的延伸

程式碼:

#include <GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(0,0.5,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glPushMatrix();

        glTranslatef(0.51,0.63,0);

        glRotatef(angle,0,0,1);

        glTranslatef(0.6,0,0);

        glRotatef(-90,0,1,0);

        glutWireCone(0.1,0.6,10,10);

    glPopMatrix();

    glutSwapBuffers();

}

void motion(int x,int y)

{

    angle=x;

    display();

}

int main(int argc, char ** argv)

{

    glutInit( &argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("Week10 TRT");

    glutDisplayFunc(display);

    glutMotionFunc(motion);

    glutMainLoop();

}
