李先生的第四周

1.從上課軟體下載freeglut

 2.將壓縮檔解壓到桌面

3.點開freeglut後復製其連結

4.點開lib後將freeglut.a復製

5.改名為libglut32.a (124KB)

6.到codeblock開新的專案 file > project,(當名為week03_mouse_glScalef)

7.將上週的10行程式貼到這次的(

#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_mouse");

    glutDisplayFunc(display);

    glutMainLoop();

}
