.2

打程式碼

#include <GL/glut.h>
void display()
{
  
    glBegin(GL_POLYGON);
    glColor3f(1,1,0);
    glVertex3f(0.0,0.0,0.0);
    glVertex3f(1.0,0.0,0.0);
    glVertex3f(1.0,1.0,0.0);
    glEnd();
    glutSwapBuffers();

}

int main(int argc,char**argv)
{
  
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("Hello 3D");
    glutDisplayFunc(display);
    glutMainLoop();

}

.3

打程式碼

#include <GL/glut.h>
void display()
{
  
    glClearColor(144/255.0,168/255.0,56/255.0,1);
    glClear(GL_COLOR_BUFFER_BIT);
    glBegin(GL_POLYGON);
    glColor3f(192/255.0,215/255.0,0.7/255.0);
    glVertex3f((95-100)/100.0,-(49-100)/100.0,0.0);
    glVertex3f((17-100)/100.0,-(106-100)/100.0,0.0);
    glVertex3f((93-100)/100.0,-(165-100)/100.0,0.0);
    glVertex3f((174-100)/100.0,-(103-100)/100.0,0.0);
    glEnd();
    glutSwapBuffers();
  
}

int main(int argc,char**argv)
{
  
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("Hello 3D");
    glutDisplayFunc(display);
    glutMainLoop();
  
}


















.4

打程式碼

#include <GL/glut.h>
#include <stdio.h>

void mouse(int button,int state, int x,int y)
{


    if(state==GLUT_DOWN)


    printf("glVertex3f((%d-100)/100.0,(%d-100)/100.0,0.0\n",x,y);
}

void display()
{

    glClearColor(144/255.0,168/255.0,56/255.0,1);
    glClear(GL_COLOR_BUFFER_BIT);
    glBegin(GL_POLYGON);
    glColor3f(192/255.0,215/255.0,0.7/255.0);
    glVertex3f((95-100)/100.0,-(49-100)/100.0,0.0);
    glVertex3f((17-100)/100.0,-(106-100)/100.0,0.0);
    glVertex3f((93-100)/100.0,-(165-100)/100.0,0.0);
    glVertex3f((174-100)/100.0,-(103-100)/100.0,0.0);
    glEnd();
    glutSwapBuffers();

}

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


    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("Hello 3D");
    glutDisplayFunc(display);
    glutMouseFunc(mouse);
    glutMainLoop();

}

改動形狀

#include <GL/glut.h>
#include <stdio.h>

void mouse(int button,int state, int x,int y)
{


    if(state==GLUT_DOWN)


    printf("glVertex3f((%d-100)/100.0,(%d-100)/100.0,0.0\n",x,y);
}

void display()
{

    glClearColor(144/255.0,168/255.0,56/255.0,1);
    glClear(GL_COLOR_BUFFER_BIT);
    glBegin(GL_POLYGON);
    glColor3f(206/255.0,215/255.0,0.7/255.0);
    glVertex3f((10-100)/100.0,-(49-100)/100.0,0.0);
    glVertex3f((40-100)/100.0,-(106-100)/100.0,0.0);
    glVertex3f((13-100)/100.0,-(165-100)/100.0,0.0);
    glVertex3f((277-100)/100.0,-(103-100)/100.0,0.0);
    glEnd();
    glutSwapBuffers();

}

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


    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("Hello 3D");
    glutDisplayFunc(display);
    glutMouseFunc(mouse);
    glutMainLoop();

}
