  1.打開 codeBlocks,File-New-Project,openGl

2.在moodle下載freeglut,ru,解壓縮後,複製libfreeglut.a檔,將複製檔檔名改成libglut32.a,在codeBlocks,File-New-Project,Glut project 開啟freeglut

3.開啟codeBlocks,File-New-Project,Glut project

    茶壺

                                            

將程式碼改成

#include <GL/glut.h>

static void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("我是08161026");

    glutDisplayFunc(display);

    glutMainLoop();

}

4.參數

5.茶壺變色

 增加程式碼 glColor3f(1,0,0);

4.加入三角形

    glBegin(GL_TRIANGLES);

    glColor3f(1.0f,0.0f,0.0f);glVertex2f(0.0f,1.0f);

    glColor3f(0.0f,1.0f,0.0f);glVertex2f(0.87f,-0.5f);

    glColor3f(0.0f,0.0f,1.0f);glVertex2f(-0.87f,-0.5f);

    glEnd();

#include <GL/glut.h>

#include <math.h>

static void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glBegin(GL_POLYGON);

    glColor3f(1.0f,0.0f,1.0f);

    for(float angle=0;angle<3.14159265358979*2;angle+=0.01){

        glVertex2f(0.5*cos(angle),0.5*sin(angle));

    }

    glEnd();

    glColor3f(0.5,1,0.2);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}
