課堂作業1:

(1)網址:jsyeh/3dcg10

(2)下載data,win32,glut32

(3)解壓縮win32,移到桌面

(4)將data和glut32移到解壓縮檔裡面

(5)點shape

課堂作業2:

(1)下載freeglut MinGW
    http://www.transmissionzero.co.uk/software/freeglut-devel/

(2)freeflut->lib->複製libfreeglut.a再貼上->改檔名為libglut32.a



(3)開codeblocks

(4)開一個新專案

#include <GL/glut.h>
void display()
{
    ///glutSolidTeapot(0.1);
    glBegin(GL_POLYGON);
        glColor3f(5,5,0);//顏色
        glVertex2f(0.5,0.5);//座標
        glVertex2f(0.5,-0.5);
        glVertex2f(0,0);
    glEnd();
    glutSwapBuffers();
}
int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("hello");

    glutDisplayFunc(display);

    glutMainLoop();
}

*點:

 glVertex2f(x,y);
 glVertex3f(x,y,z);

*色彩:

glColor3f(r,g,b);
